Thank you for taking the time to use the schematic. The schematic is priceless now days, and learning NEVER stops! Semper FI, USMC.

[@OnlineMechanicTips]

Yes, and thanks for watching. Remember to thumbs up the videos for me, thanks

[@dsacksphat]

Well explained my guy.. Researching why I'm not getting a spark from Ignition Coil..

[@thisguysgarage]

Thanks for keeping me in the know JT

Hi, thank you very much for your videos, in this one you explain very well the situation. I have a two questions: 1) I have the same problem, with a Dodge Avenger 2008 2.4 L 4 cylinders (very common on chrysler huuu), but in this case is the P2305, any way, this misfire problem is intermittent, it does not misfiring all the time, just randomly, I have replace the spark plugs and the coils (all 4), and some times the engine misfire, and I have change the ignition coil connectors because they burned down (4 of them), and when I move the connectors or the harness, the engine vibrates and one of those related codes appears. Do you thing the harness is open in some point? is the resistance high and because of that the ignition coils are getting very hot and as a consequence the ignition coil connectors are burning down? 2) My second question is what web page (or software) is that? where you can see the schematics... I have the same information but in PDF, and I have a subscription on ALLDATAdiy for my vehicle, but I've never seen those schematics. Thank you very much in advance.

[@dugy40]

do i have to test coil one or can i test any coil to see if the pcm is cycling?

[@dugy40]

if truck is running no need to check middle pin right? where can i buy a subscription to where u got that diagram? ty

[@sarahobrien3379]

Did you make the video on doing a load test?

[@ChrisFloX]

Have the exact same problem with my '07 jeep patriot and is currently at the dealership.

[@LaughingChaos]

please let us know what the problem was when you find out.

[@dwiththev6159]

What was the problem

[@hairlyfeyanni3044]

I’m having the same issue p2305 I turned my car on one day left it to warm up a few mins later I come out to the check engine light on and smelled burnt wires smell, I pop the hood and see the 2nd coil smoking white, when I try to take it out it’s stuck it melted, I got a new valve cover and gasket new coils and had to order a pin connect currently waiting on that but the car still won’t start it’s a dodge caliber as well I have to try to check all the fuses like you said and hoping that the broken pigtail fixes it

[@scuzzyfpv]

I have a 2012 Wrangler with 3.6L. I have been chasing my ass with an issue that doesn't occur very often. Randomly I will get cylinder 6 misfire with a P2317 - Ignition Coil 6 Secondary Circuit - Insufficient Ionization. I have replaced coils, plugs, and PCM and cannot get this to go away. Sometimes it comes back every few months, sometimes it takes a whole year before it shows itself agian. Each time it would randomly go away on its own. Any thoughts?

[@jessicalafave946]

hey buddy i have an old truck, 2003 dodge ram 2500 with a hemi, looking for help to figure out the problem bank 4 gives code p0354, did a pcm swap like you showed on your channel married key pcm and the ignition little black box to truck, truck starts all good but still spark from coil not there giving code again p0354 i checked the power at coil plug and its got power with test light any ideas thanks

[@user-lc2nj3fd9j]

Gracias

[@nigelnkunzi6414]

I do hv the same problems on my dodge caliber at first when I did engine overall I started the engine cylinder 1 was firing good cylinder 2 and 3 are not firing then cylinder 4 is firing so I switch off remove the batteries put it back now the first cylinder n firth which were firing are not firing the second and third are the ones firing I swapped coil packs jus to confirm if they are not working they are working if I can put spark plugs while the coil packs are out side all of them are firing well but if I put them back 2 cylinder will not fire either 1 or 4 my not fire or 2 and 3

[@servantofyahuwah2486]

I have a 2003 ram 2500 5.7 hemi with a code po353 #3 cylinder misfire. I put new spark plugs swapped coils and wires and nothing changed. I thought it was the pcm. So I bought a refurbished pcm and hooked it up. Then it showed a po352 # 2 cylinder misfire. With the refurbished pcm. So they sent me another refurbished pcm and i hooked it up and it showed a #6 cylinder misfire. Any ideas? Thanks.

[@user-sp5bn6ye8y]

How about if the coil pack windings were cooked and blew out. Likened to the coil be supplied non-stop 12v and keeping it on at basically 100% duty? The high voltage (secondary) winding swelled it due to heat and overload. It's a 2009 Ford Flex. Cylinder 5. Destroyed 2 cools. Just replaced the pcm and new coil pack and its running. Just concerned it might happen again to that one coil. Wiring hasn't been touched or disturbed

[@dugy40]

my truck is running so you said if the middle pin is not cycling the pcm is bad. thats confuses me, of course its going to cycle because the truck is running. right?

[@vempatisivanarasimharao6620]

What will be the solution if one of my coil is getting continuous signal from ECM not flashing signal??????????? please respond

[@LaughingChaos]

@Online Mechanic Tips i did the 2 test with the 12v light for pin 1 ground all lights up for pin 2 no light flashing at all for all 4 of cylinders is that a bad thing?

[@LaughingChaos]

@Online Mechanic Tips Also i changed crankshaft and the 2 camshaft sensors afther that i cleared the codes took the car for a spin codes did not come back yet but problem is still there.

[@dugy40]

where can i get a copy of the diagram your using? ill be glad to pay for it. ty

[@renejacques8288]

So pin 2 is the signal in your example? And to see if the cpm is sending signals, I should make contact with B+ on my voltmeter and use the signal wire as ground to see if there is voltage? I have a '95 Nissan Maxima.

[@OnlineMechanicTips]

Depends, is this a 3 wire connector? Also are you subscribed to the channel?

[@renejacques8288]

@@OnlineMechanicTips It's a 3 wire connector. I was just wondering in your example if pin was the signal wire so I could try the same on my signal wire.

[@adanmagana2017]

Having a misfire issue on entire bank (bank 2). Vehicle is 2013 Jeep Wrangler. Will this work in my vehicle? My mechanic thought it was a bad pcm

[@adanmagana2017]

Also, it’s important to note that we ended up buying a new pcm and the issue persisted. We sent the replacement back and got another one. Same thing. I’m wondering if I can use this schematic to troubleshoot instead.

[@dbwiskus]

Can you do the same test light testing on a 2 wire coil?

[@frednice5539]

I’m trying to find this out as well, my dodge only has 2

[@NekuNuy]

i tested continuity with the car on, on one of the coil connectors it was duty cycling like normal, but on the cylinder mine kept melting it was constantly on, does this inherently mean pcm?

[@vempatisivanarasimharao6620]

did you find the solution i am also getting continuous signal what is the solution

[@NekuNuy]

@@vempatisivanarasimharao6620 i did find the solution, it was my pcm, after buying a new pcm from flagshipone and installed it the issues went away completely

[@tabobtavio3054]

I am confused when checking the CPM negative reference signal. Because, I see you use a test light connected to battery positive which is 12vdc !!! would not damage the PCM ?

[@OnlineMechanicTips]

What kind of car are you working on? Also are you subscribed to the channel?

[@tabobtavio3054]

@@OnlineMechanicTips my question is general...not subscribe yet....fist time watching your channel

[@jasonbender2459]

THE ANSWER is nope. thats what the factory manual says to do. if the pcm can handle the 12v from the coil it can handle 12v from the lamp.@@tabobtavio3054

[@joeshaffer97]

I got a 04 ram with the 5.7 it's telling me coil d primary circuit fault which cylinder is that?

[@fru7832]

Looking at it from the grill, it would be the 2nd coil from the front on the left side.

[@jasonbender2459]

4

[@dugy40]

Bud watched this again. Just because testing those pins says it’s good that doesn’t mean pcm is good. It could be intermittent problem on another coil.

[@OnlineMechanicTips]

Im not understanding this comment, or is this a question? What kind of vehicle is this? Also are you subscribed to the channel?

[@jessicalafave946]

sorry its a 5.7 hemi i just hope i didnt blow the new pcm again also no other codes just the one code shows up p0354 cylinder D thanks again
