Ford Ignition Coil Primary Codes P0351-P0360 Diagnostic Walkthrough

[@hoganhogan952]

You are the best! A couple dollar noid light found the problem in 30 seconds that I struggled trying to solve for 2 days. Saved a trip to a shop for sure because I was ready to give up.

[@thepracticalvideocreator5932]

Thanks for another great diagnostic video. The P0353 code I experienced on my Mazda Tribute ended up being an issue with the Powertrain Control Module. At first I thought it was the #3 coil since I discovered it had a large crack in the plastic housing. I'm no expert and can only speculate, but I think the defective coli caused the PCM to fail. I found a company that rebuilds PCM's and their warranty is strictly void if you use any coils other than genuine Motorcraft. The defective coil on #3 was a cheap aftermarket part. I sent in my PCM for repairs and swapped out all six coils. Back on the road again!

[@robertstercraw9284]

Thanks for the video - used it on an older Ford ZX2 with a coil pack ignition that ran like crap and was throwing a P0352. Found one of coil trigger wires had rubbed through and was contacting the bracket at the rear of the cylinder head. Appreciate all the help you offer up!

[@Ed-xc5hi]

Nice video. I had the P0351 code pop up. I moved the #1 cylinder coil to the #2 cylinder and then I got the P0352 code. That's how you know if the coil is the actual problem. I would do that 1st since its less than 5 minutes and a really easy job.

[@jimallen7254]

Man, this is quality instruction. Thanks a lot for the info, it's much appreciated.

[@christhefistful]

Great walk through, Ford main office should offer you an instruction position.But of course we would want you to keep doing this for all of us.

[@FordTechMakuloco]

Thanks!

[@bradleyschwarz8458]

FordTechMakuloco I have a 2014 F150 3.5 with 120K. I had a misfire on number 5. Replaced all the plugs with motorcraft and gapped to .030. Replaced coil on 5 and all the boots to the other coils. While I was there I cleaned all 3 MAP sensors. Ran great for a week and now it runs even worse than before. Has two codes; P2300 and P2303. I checked all the pins in the coils and in the harness and checked all coil wires for chaffing. All looked good. Do you have any ideas?

[@mysteryboyee]

had a p0354 on my 98 expy, didn't find this video until today, but i did fix it already, for me the solution ended up being cutting off the old connector, and crimping on a new one, once started it immediately ran significantly better, so for anyone out there also getting primary ignition coil circuit codes, just because the coil and spark plug are both fine, doesn't necessarily mean that your PCM has gone bad either, it very likely could just be the connector itself has worn out

[@ivanlaney2336]

I have an 07 5.4 Expy, I've had a p0351 code. I have the constant hot side but I can't find a diagram to check the " pulse side" pcm pin to the #1 coil

[@TypeOneGuy03]

what pin/cable is it for P0354?

[@hectorgonzalez5258]

Watching his videos it's lake going to school at your favorite teacher thanks for sharing keep up the great work

[@todd3806]

Thanks!

[@lilypondgarage2968]

When I work on fords this guy is my go to

[@protege1962]

Got 3 party busses cutaway van buildouts, with v10s changing coils on those is a real pain no room to move or wrench. This helps so much. These busses talk to each other when one goes the other busses listen then they go also!

[@indyfosho5458]

Best diagnostic video I've ever seen. Hands down. THANK YOU!

[@shellyterrill5066]

Thanks for the video. We were trying to decide if we needed to replace the pcm as well as the ignition coils in our 2006 fusion, and it sounds as if we should go ahead and do that as long as we have to replace the coils. The side comments you made about the earlier fusion models were very helpfull

[@mariobueno3368]

Very thorough and precise as always Brian. Thanks for all the content you put out!

[@froggfather]

Awesome video man!! I don't think there's anybody that could do a tech/diagnostic video any.better than you do! Stay on it please!! Thanks!

[@mariagarcia9017]

[@Def1antone]

if you do not have a noid light, you can use a 194 light bulb. fold down the pins, and insert in the plug.

[@csaleen302]

Thanks so much for this info. You saved me alot of time with my p0355 code. Narrowed it down to Cyl 5 from a generic primary circuit fault.

[@vinniez2188]

What was the actual problem. Coil, wiring?

[@rakchazakamat6320]

Thanks man for showing step by step you explained everything good 👍👍👍 good job

[@richmhwd]

Great video. Thanks for mentioning the issues with the ford fusions.

[@DallasAutoDiag]

Im working on 13 3.7L that has all the coil p0351 through p0356 codes, yet the car runs but with a misfire.

[@Dxfactor24]

Car just started this after running out of gas.

[@RoOniGame]

I have this same problem you know whats its ?

[@waiting4aliens]

Thank you. Very well presented, and able to transfer your diagnostic approach to other problems.

[@AH-ky7xb]

Very clear and methodical explanation. Thank you.

[@billneville3405]

Great video. I've had a P0356 on and off for a year on my 2008 Taurus X. Have been hoping it was not the PCM. Now, I have hope.

[@oldawg8643]

Very good vid Mak...I've been fighting this prob and I've watched numerous vids and yours is by far best. Thanks a lot, it saved me some money and maybe a lot since it's a Navigator.

[@JasPlun]

I have a 2015 Fusion SE 2.5L ENGINE. I replaced all 4 coils,plugs, and injectors and still getting a periodic misfire in cylinder 3. I see you mention some of the newer model fusions sticking on. I have a Ford tech that started his own shop after the dealership he worked at for 20 years sold. Problem now is I cannnot get it to throw a code when it is misfiring and its periodic so getting it to actually misfire in front of him has been difficult. Visually inspecting the woires they all look good with no corrosion seen, but it could still be a wiring or other issue. This particular Fusion has been a lemon it has 50k miles on it now. At 22k miles it died and was towed in. Under warranty they had to replace the Head as they discovered 3 cracks from the forge. Its been 2 years since that repair and ran great until now. Checked the oil and there is no water found. All the plugs looked good when I replaced them saw no indication of water so I do not suspect anything from that repair. However I do remember them having an issue with an injector after the head was replaced, but they resolved it. I am now just waiting to get another engine code after he cleared everything so he can see if its consistant with same #3 cylinder. Thanks

[@G_Rapids]

Very informative, 99 f250 has a misfire on cyl#7, has signal all the way back to the PCM but i did not check what the ohm reading was..checking that as soon as i get home

[@leeburnley]

Just saved me from buying a pcm I didn't need, much thanks..

[@snyd3rcg]

Your stuff is great! I scan through your videos before I dive in! Very helpful and Great Job ! Keep it coming Man!

[@chadboatwright5752]

Hello yea I have a 5.4 2006 ford f150 it says all coils are bad but the new coil I bought yesterday can 7 coils go bad at once ?? Need help paid 900 at shop and still not fixed paid for upper Manafold said it was leaking seals was bad

[@garykipfer3004]

Thanks for the info on the Noid Light kit

[@bobwarman6706]

This is Omar's friend... I do not think of this noise as a "knock" but as a light "tapping" sound, you can best hear it when the sound is reflected off of a wall with the window open. Is present ONLY when accelerating, if I take my foot off the gas pedal it stops. It increases and decreases with engine speed and is present when engine is hot or cold. Thank you for your help. Bob

[@Mebob2001]

good video dude. in the Gm world i can say the newers cars are all testing circuits for you, there not perfect by any means but they do poiint you in the right direction! cept there usally generitc codes which will give u same diag if you didnt know it was open or whatever. like a c0045 sym 00 or o6 open or shorted and signal erratic, you would think WSS is bad when most of the time you see thos codes togethor its the harness itself that has a broken wire inside the insulation

[@1hlyGOD]

Lot of great info. But would like to see how diagnose a six cylinder....cause as you know intake covers the back coils.....can turn on to check pulse. I'm sure there is other ways to test. Great video again thanx for it!

[@GeneralMechanicGA]

Man love the info Now I’m having this problem on a 04 mustang v6 3.8 Just don’t have an idea of how go about the wiring on the coil connector since is only one and only 4 wires on it But I will try this and hopefully gives me a way to go from there if you had an idea on how to go about it it’ll be greatly appreciated

[@bobbyholmes3985]

Thanks for your helpful information. 🙂

[@sryth1]

Any problem with swapping the coil with its neighbor and seeing if the code follows it?

[@darebros610]

So the connector for cylinders one was not getting a pulse. Changed out not only the wiring harness but also put in a new PCM. Spark plug changed and ignition coil. Not sure why it’s still not sending a signal to the 1st ignition coil. Please help

[@zwilhelm]

Just had an issue where my 2012 f150 ecoboost was idling weird. I had just had all coils and plugs replaced and was scratching my head. Had P0351 and after visual inspection realized cylinder number 1 coil connector was not fully connected. Reconnected it and have no change in idle. I assume im looking at a PCM replacement now? I think I am going to have a hard time explaining this to them and making them pay for it. Any suggestions?

[@NicholasWM2044]

I've been getting p0354 code on my 08 focus se 220,000 miles with a very very rare random intermittent misfire that will only misfire sometimes for maybe 2 seconds or for 25 seconds, and then it goes back to running normal for 5 to 20 minutes until the next short musfire., . At first I found oil on the spark plug for cylinder 4 so I installed a new valve cover gasket. I also got all new spark plugs at that time. The issue continued so I got all new coils. The issue seemed fixed for about a week, but then came back. I did notice my fuel pump making noise so I got a new pump and will be installing this weekend but i wouldn't think the fuel pump would affect just one cylinder and only giving that one specific code that is directed towards and electrical problem. My question is, since it's rare for pcm's to fail, is it more likely that the wiring has an issue or the pcm. The misfire has been happening a lot more often lately slowly slowly misfiring more often. so I'm really trying to narrow this down. And my second question, IF a coil driver In the pcm were the culprit, could it be intermittent. Or would the coil driver just fail and stop pulsing. To be honest, it's the fact that it's so intermittent that is making this so difficult because the tests all come back normal unless I catch it at the exact moment of misfire.

[@JohnDoe-lt9sg]

If it misfires at idle you can wiggle the wires all around and see if the engine runs better or worse and can narrow down problems in the harness like that. Overall you don't want to run a misfiring engine long, esp if it's blinking the CEL because unburned fuel is going down the exhaust onto your o2 sensors and cats.

[@mikecont9742]

Great video walkthrough. Thanks for taking the time

[@blackriflex39]

thanks .. ive got a 2006 ford mustang gt that is throwing all 8 primary coil codes at once. its only noticeable at low rpm below 2,000 . i had a alternator melt at the power wire a month before this started ... think there is a connection? ive been told a bad alt will burn up a pcm

[@tanji9]

Where are you located friend...in Canada toronto ?

[@timwallace6486]

Thank you for this video. I am confused with the error codes and was hoping you could clarify the issue. I have a question about the P0303 error code. This code indicates a misfire at cylinder 3 but I found a website that states that a common mistake people make is that the P0303 code is referring to the third cylinder in the firing order, not cylinder number 3. The article states: "P0303 is a cylinder specific misfire code, which means that Cylinder 3 is misfiring and causing the code. An important thing to understand when finding the location of cylinder 3 is that it's going to be the 3'rd cylinder in the firing order of the vehicle, and not the 3'rd cylinder that you might see when looking at the engine." My 2006 Mercury Montego has a 3.0Liter v6 with a firing order of 1,4,2,5,3,6. The third cylinder in this firing order would be cylinder 2. Do I have a misfire in cylinder 2 or 3? Can you please clarify what is meant by cylinder 3? Thank You

[@deanm3464]

Very helpful yet again

[@BywaysnoHighways]

Followed all your steps and triple checked.. I re-wired from PCM to coil thinking intermittent break. Still No Joy! Being told the noise suppression capacitor can throw a PO35X code. I see corrosion on the capacitor terminals and about to remove test and clean them. Your thoughts?

[@zacharybinckley]

Had a p0352 on a 2000 6.8, did your steps here with no success. Noid light flashed and all. Ended up tracing it back to the pcm pin being slightly pulled out. What a pain, ford could've put a 1/4 in slack on those pcm wires. They're so tight.

[@David-xb4ew]

Hey man great video s and I followed your guide step by step but I’m still not finding the issue. So I have a 98 e350 5.4l. I’m getting codes p0354 p0355. All 8 of my coils are have the same ohms reading. Both cyl 4 and 5 have power on the positive side with the key on and I’m getting a great signal while running on the other wire. No grounding issues anywhere but still not running good at sll. It’s misfiring with low power. (Note that my number 5 coil is actually brand new). I’d love your input. Thanks in advance and thanks for the video!

[@greggyfree]

I'm getting p0352, p0353, p0355, p0356, p0357 on my crown Vic. I changed the pcm and the coils, still can't find the problem. Changed many other parts as well. Doing a compression check tomorrow. I guess I should rip apart the harness. I hope I find it.

[@HemiChrysler]

P0353 on a Ford 4.2 V6 is not so easy. It's ignition circuit C, which seems to correspond to the middle 2 towers of the 6 pack coil pack. The middle 2 towers should fire cylinders 2 and 6, but these cylinders are down because there's no output from the coil. I replaced the coil pack, no improvement, thus I suspect a broken wire somewhere between PCM and coil pack.

[@Gears.and.Gadgets]

I see it can be more involved than just switching coils to see if the error code followed to that cylinder. Thanks for pointing that out.

[@compuzen]

Hello sir, Thank you very much for this helpful video. My wife's 2011 Escape XLS 2.5 is getting the error for a misfire on Cylinder 1. I've replaced the ignition coil and spark plug, checked the common and signal wires, and that the injector is getting a pulse. All that checked out but the light came back on and it randomly runs and idles rough. I'm assuming the next step is to replace the fuel injector and fuel filter, but would greatly appreciate your thoughts on it. Thank you sir!

[@FordTechMakuloco]

+Dennis Johnson Was there oil in the plug well. Are you using a motocraft plug and coil?

[@compuzen]

Hello sir! Thanks for the reply. The old sparkplug looked dry and clean. I replaced the original with a Duralast C1658 and sparkplugs with Autolite Iridium XP. I replaced the fuel injector this morning and it idled well for a while. We'll see if the ECU finds a fault after we drive it for a while. Thank you again for your help!

[@compuzen]

+Dennis Johnson Hmm, the light came back on again on her way to work this morning. I'm not sure what it could be now. I've replaced the ignition coil, spark plug and injector. I also get a pulse on the plug for the injector and ignition coil.

[@RANS87IROCZ]

+Dennis Johnson I recent did same thing and checked everything I kid you not the spark plug I got from AutoZone was bad! after all I went through I ended up trying another new plug and bingo

[@davidsabin1186]

Worked perfect ,it helped me a lot, thanks

[@joecaci4122]

Nice video man. I have a 2001 transit connect with the 2.0 and it has a persistent p0354. New coil and connector on this thing and the code will intermittently set Customer says the van does in fact misfire sometimes but only for a few moments. I have tried to recreate this with several road tests and by moving the harness while in the bay. Never got it to misfire. Any advice on tracking it down in this situation? I am thinking about running a new wire for the control side to the pcm and trying it again.

[@MIdru313]

How would you diagnose this issue if it is a V6 engine and the code is P0351, P0353 or P0355 and the misfire issue is on the rear cylinder bank and is covered by the upper intake manifold?

[@whirlwind8825]

Would it be possible to take a metal plate with a bolt like terminal, then strap the coilpack to the metal plate and create a gap between the coilpack and the bolt. Then ground the body of the coilpack =bolt hole on coilpack to the plate.. Then run a 12 volt pos to the coil pack and then run a ground wire from the battery to the plate. Then run a switched ground wire from the battery to the coilpack neg side .... Then you could turn the ground on and off and see the coilpack fire.... Do you think this idea would work ?

[@juliobarrios2420]

Hi My 2006 Expedition is presenting that same code for all cylinders p0351 to p0358 before that she had a previous failure that did not go over 3 thousand rpm then it began to misfire to the point of not wanting to roll, so she got home and here she comes throwing smoke, and it didn't ignite anymore, when checking the only thing we saw was one of the detonation sensors cut off when correcting that it lit with all the coil codes p0351 to p0358 where do you recommend me to check I'm an enthusiast in mechanics but I know very little about automotive electronics

[@rkey1012]

Great Video, helped a ton in troubleshooting.

[@caper736]

I have an 2008 f150 with a P0358 code. I changed the coil ,plug and put a new pigtail connector on to the coil. I was still getting the code so i took it to my mechanic. He checked for constant power on the common side of the connector and put a noid light on and not getting a pulse. He checked for continuity from the coil connector to the pcm connector and said it was good. He thinks its a bad pcm. Is there anything else that should be checked before getting a new pcm? Thank you!!

[@RoadRunnerRV1972]

I have a transit connect 2013. Lost cylinder 1 and strangely air conditioning (at the same time) I’m leaning towards a pcm. 1 coil pack works on other cylinders when test at coil plug grounding signal isn’t steady and almost stays on or fluttering rather than steady with tdc. Ohm test I’m seeing .3 on a fluke 88 through harness. At this point I’m not sure what else to check.

[@broderp]

So you say bad PCM's are rare, but based on your video, (you have proper voltage to coil, proper coil resistance, proper ground pulse signal and continuity on the PCM wire from the connector to the PCM) you have a bad PCM. Maybe not so rare?

[@jerrybass6784]

Hetting a P0356 on a 3.5 Edge. I get good pulses with the noid light except for the offending #6 which stayed on and did not pulse. Bad PCM?

[@hawaiianf1504]

Is there a particular NOID set that you recommend for home garage use? What about a better set that can test other vehicles or are the NOID lights all the same as long as the plugs fit? I have 2009 Ford 150 4.6L 3V and a 2007 Toyota Camry V6 3.5L 2GR. I checked on Amazon and Ebay and there were too many that looked all the same. Not sure which is more reliable.

[@FordTechMakuloco]

HawaiianF150 2009-4/6-L3V They all work in the same way. I have a kit like this one that works for just about everything-www.amazon.com/gp/product/B0002KO4I2/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0002KO4I2&linkCode=as2&tag=fordt-20&linkId=WNXAXXZ37UL4JD2F

[@hawaiianf1504]

FordTechMakuloco Thanks! Have bought several of the items you have recommended in the many videos you've shared with us, Have not been disappointed in any tool purchase I've made because of your suggestions. In fact, my son wants some of the tools I've bought. (no way Jose;) Please see my comments in your new Milwaukee Tools video. No email received yet. Sent my direct email address twice. Box is ready to ship just need address where you want it delivered too. We really appreciate all of your videos. Best video's on You Tube. Easy to watch and follow. Very informative.

[@claughnernavy]

Love your stuff! And appreciate that you share the info. You said that on three prong coil systems the testing is different. It is, but some Late model trucks have three prongs but only 2 wires in the connector. Little tip for those who get discouraged seeing three hole connector. Look inside to see if three prongs pare present. If not this test will apply to you

[@mikehlrtfo1]

I have a definite head scratcher. I have codes for all 8 coils being primary circuit open on a 2013 f150. Would this be a bad ground, or a bad pcm?

[@brandongoreman7747]

I just went through all of this on my fusion. 500 for new coils, you must replace all of them! 500 for a new pcm. Tried to get orig repaired but it was bad. Now i need to tow it to the dealer for a "perimeter reset".

[@redeemedrides2528]

Got an 05 escape throwing the different cylinder malfunction codes like this and I used a test light getting a ground pulse but not like you got mine only pulses every 5 seconds or so

[@Hutchy45445]

Very good tutorial, as usual, gives me a direction to begin troubleshooting. However, I have the left bank not functioning at all, without codes coming up? I think I’m chasing a ground issue ;( Thanks again!

[@joehyundaitech7961]

Brian hi I bought a otc noid light for my 2003 ford focus 2.3 and it wont fit the pins are to wide when I go to plug it into the connector on my cop

[@SilveradoXST]

Ok, here's a crazy find. What's wrong when 3.18V is present on the ground side? '06 Tribute with misfires on 1/4 cylinders. All the common items in your video check out.

[@williamgonzalez487]

That’s a great instructional video. In having that issue (P0351) on my 2005 Expedition , but also I’m getting lean mixture fault. I replaced the modules, but would like to know the resistance for such . Also I heard that could be a vacuum leak. Thanks for your help.

[@juniormorales559]

Did you ever figure out your issue im having a p0351 as well i have a 02 expedition

[@williamgonzalez487]

All I had to replace all ignition modules, plus the throttle body

[@jameshill2188]

Well this code came up on my 2006 Ford Expedition and found that the coil was not properly seated on the plug. The plugs had been changed a few months ago, so I guess it just worked loose, although the bolt was tight! The code has not reappeared so far.

[@vallieresk9289]

I have a 2010 Ford fusion Hybrid and getting all coil codes, 351 351 353 and 354. I'm thinking it's likely pcm since they are all coming up. Is 2010 one of the years they were troubled?

[@slappy1475]

I have around 40 hours into this same problem and have replaced and troubleshot 90% of the system. Did you ever get a fix for this issue with all coil codes on a hybrid? Replaced PCM, then oem coils and plugs. My car still starts, idles rough then shuts off automatically. Thanks.

[@HardKnocksForge]

I've read on forums and seen other videos where they say that if you have a problem like this it's better to replace all coils and repair/replace the pcm. Their thoughts were that the short in the coil would damage the pcm. Also if the pcm were bad it would in turn short out the other coils on start up. What's your thoughts on that? Would it be a big deal to just replace one COP if that was the only problem? Could you swap COPs from one cylinder to another (say cyl 2 to cyl 4) in order to verify a bad COP (if all you had was a code reader and no DVOM)?

[@hectorruiz5821]

Hey your videos are great a lot of good info . I hope to see if you can help me out 1997 f150 4.2 code p0008 engine has no power and it only runs if I disconnect the mass air flow meter but it’s doesn’t run good. Thanks if you can get me started diagnosing .

[@justinbeam5103]

What if I’m getting the pulse with a noid light, I swapped ignition coils with another cylinder and I’m still getting p0360? Spark plug?

[@ccf3195]

Same problem. I changed my coil and spark plug to code p0357 and it still pops up. I also changed my harness because it was disconnecting but my vehicle is still idling and shaking. Confused

[@mikeblake6265]

How would this apply if it pulls a PO351 but also PO301and a PO304 and a PO316

[@browngal00]

If you have to replace one coil should you just replace all of them?

[@protege1962]

Thank you great job of explaining

[@cobracommander2007]

I have been shaking wires and testing fir continuity with no luck. Moving COP and spark plugs do not shift the problem. My mechanic says he does not see anything wrong but he does not specialize in PCM repair. What are my options? Car does not misfire on start. Load will trigger it but not always

[@fredsolomon3rd6969]

Hi I'm working on a 2003 Ford expedition. It keep blown coil packs , 1 every 4 months. It will be different ones. It been tuneup. I use dielectric grease. I'm using o'reillys grey and blay cool packs. Can you shed some light on this.?

[@MegaBobson123]

Do you think crown victoria is a good car?

[@FordTechMakuloco]

yes

[@TurdLocked]

Great car, I have 4 of them and just installed a fuel pump and lo and behold, P0351 code pops up. And the fuel tank straps are fighting my attempts to thread the bolts back onto the studs. Besides that, great cars!

[@pariahneiderleben3445]

Man I'm having this exact issue an I've followed along step by step,so far so good. But my codes were 351,352,353,354. In order to get to those,I had to disconnect and take off almost everything..how can I check the pulse power if I can't start the car?

[@cobravenum]

Is there any reason why multiple ones would come on. I had a code for cylinder one. Changed the coil and now getting P0351 through P0356 VOLVO CX60 TURBO still running rough

[@jonesgang]

So if I'm getting faults on P0352-P0356 but not for P0351, basically cylinders 2-6 but not on cylinder 1. Chances are my ECM is causing the problem.

[@JTucson]

Do you know if the 2011 Ford Fusion/ Lincoln MKZ Hybrids had PCM issues? I have an error code on all the cylinders 1-4 for an open circut.

[@kyleharn3920]

Hello, just recently replaced spark plugs on my 2011 f150 5.0. I installed ngk iridium plugs. Shortly after installing those I get a shake and a p0354 code comes on. I replaced the coil pack and that did not help. While I was doing the spark plug change I did break a connector and replaces the black portion that plugs into the coil pack. Do you k ow if the coyote motors are picky when it comes to spark plugs or do you think I messed something else up? Any help would be greatly appreciated, thank you.

[@adrianwaloshin7025]

Kyle Harn if you installed a new coil on plug and spark plug and it doesn't fix your problem. Then either there's a broken wire or you need a pcm. If the plug came unplugged while the engine was running. Then install and new pcm. It's a big No No to unplug the 3 wire coils while the engine is running. You'll get a voltage spike that takes out the coil driver in the pcm.

[@kyleharn3920]

Adrian Waloshin thanks for the reply! I am leaning more towards a broke wire since it is intermittent. Sometimes it will be okay and sometimes it misses

[@trknjoe]

I have an 04 F150 5.4 3v (11th gen) I’m getting 3 codes P0351, P0353, P0356 I replaced all coil packs and pigtails and still have problem. Ford has been testing now for 3 days with no luck. The codes are random. Sometimes all 3 at once , other times they rotate. When you clear the code it runs fine, a few minutes later it starts again. Any ideas or suggestions? Hoping you can help out a fellow Devil Dog!

[@RickyPisano]

I thought on a Duratec DOHC V-6 that the 1, 2 and 3 cylinders were left to right looking at the engine on the firewall side, Bank 1 and 4, 5 and 6 were in the front on Bank 2. Is that what you meant by front?

[@FordTechMakuloco]

Front of the engine on the firewall side is cyl 1.

@@FordTechMakuloco Thanks. That's what I thought you meant. I was scrolling the comments and saw that one guy telling you that you had the order wrong. I told him the order and that you were correct and he misunderstood you. You're the best at helping me with my 2005 3.0L Duratec V-6!!

[@w9x7cv3vg6]

I thought you had a problem,what was it,the power was going through to the end as shown on the noid light,but u did not show us the ohms found if u hit the right pin on the pcm connector..what was the problem here,did u need a coil or just what...thanks

I've got a 2006 Fusion 3.0l, with a P0353 code. I bought the car used with that code, so I replaced all 6 coils and plugs. I still have the same code showing up, engine missing also. What is the best way to unplug the #3 coil with out removing the intake?

[@tomasdusejovsky770]

What should I be looking for further on if all wires are ok and pcm sends P0351, P0352 ? Plugs, coil packs and connectors are all right (verified )

[@tompenick9368]

At 1:20 you say that the numbering goes from left to right and on the V6 and V8 engines it goes from front to back. This is NOT accurate. On the 3.0 V6 engine, the back three cylinders are 1,2,3 and the front three cylinders are 4,5,6. I had a P0352 Code in my 2008 fusion. Based entirely on your statement, I replaced my FRONT three coils/plugs at the same time I reinstalled a rebuilt PCM. Ran well for several minutes, then I fried coil number 1 and probably my PCM too. You might want to edit that statement about front to back cylinder sequence.

[@FordTechMakuloco]

Yes my information is accurate you misunderstood what I was saying. I would imagine after 10 years of Ford drivability I would know that cylinder order. Especially because every Ford engine is the same you really cannot mess it up they are always in numerical order starting on the right bank FRONT TO BACK then it picks up again on bank 2 FRONT TO BACK in numerical order. If you did not replace your pcm with an RM suffix part number then this will happen again. Anyone who has the ability to reprogram the pcm and PATS keys should know the cylinder ID for each cylinder vehicle they are working on along with applicable TSB's. I hope this helps!

[@csaleen302]

Criticize the free information you are getting. How about you do a little leg work yourself, double check the info, before you go blaming someone else for YOUR screw up. Not like you had to pay for any of this info. Its a starting point.... Or if you don't understand a firing order maybe you shouldn't be working on your own shit.... Just sayin

[@RickyPisano]

The 3 cylinders on the firewall side of a 3.0L V-6 are on Bank 1, the front of the engine left to right 1, 2 and 3 and on Bank 2 are 4, 5 and 6 left to right. The firewall side is the front.

I have 6 of these codes p0352 thru P0357. It misfires at stoplights and hesitates at times at low rpms. I've changed the computer and am pulling my hair out. Drives fine on the highway. Help please

Alvaro Silva like a bad intake/exhaust valve ? Was it bent? If so, how did you find out?

[@Whisky4Brekfest]

wanting to know before I take my PCM out to have it repaired, my #2 coil had melted, replaced with a new one, upon firing it up, it melted again almost immediately. is the pcm the culprit here?

[@FordTechMakuloco]

+Ronie Ochoa yes very common on the escape and fusion models the pcm driver gets stuck on

[@alvarosilva957]

@@FordTechMakuloco my ignition coil isnt working. And I noticed when I umplugged my ignition coil harness it didn't do anything. Should I be looking into the Pcm?

@@FordTechMakuloco Might have missed it in the video , will look again but How do you know a driver is stuck on? Had a 2005 e250 5.4 come in with a Cyl8/Coil H primary open. found the coil "exploded" Replaced coil all was good until a month later. Now Fuse #8 for ecm relay and coil power blown and van does not run. I unplugged the cyl8/coil H coil and the Van will run. Thats as far as I got with any diag.

[@mikeburrill779]

So would you have to know what the ohms would be on the coil if it wasn't open

[@youngmafi5609]

What happens if eveything is working including pcm? Then what do you do next?

[@willadcox9552]

I have a 03 2.0 sohc focus its has a p 0352 and I've put a new coil and spark plugs along with new wires and it still has the code. I found I have no fire at cylinder 2 and 3. should I be looking at the ecu next?

[@Makinson480]

I'm having the same problem this is the first time it gave a code for anything. on my 2001 Ford mustang gt I have a my code is p0355 I did all the test when I connected my noid light than started the car the cylinder 5 hardness there was ground no pulse could that be a large change the PCM is done for.

[@KrazyBear918]

Hey there quick question. I have a P0356 code. I have several spare coils and plugs (previous owner), can I just try swapping new ones in on the cylinder and hope it clears the issue? Will the rare possibility of the pcm being bad foul or damage the new coil/plug? Thanks!

[@Whisky4Brekfest]

Brother I can attest that it will damage the newly replaced coil if the pcm is at fault. I just replaced my #2 coil which had been fried and immediately upon startup I had a rough idle still, checked the newly replaced coil and it had again melted.

[@KrazyBear918]

It would be nice if there was a strait forward way to test the pcm. I ended up just replacing all my coils and plugs. Haven't had a CEL or issue since.
