A 2018 SD Premium video - Ford F150 4.2L Waste Spark Ignition, One Coil Not Firing

[@onemechca]

This video looks like it was before Caleb as camera man. Lol. . It really doesn't matter. I have been watching you for 8 years at least .This is my 1st time responding to your videos. As usual this video is informative and educational like all the videos you and Caleb produce. Your explanation on how circuits work is phenomenal (circuit design)......BAR NONE.......BAR NONE Anybody that gives you a thumbs down needs to have their head examined. I am a former auto tech ( Mazda) for 25 years that eventually quit because of flat rate. I am now working in the forklift industry. I wish I found you while I was still in automotive. I apply your videos that I watch to troubleshooting a fault in a electrical ( 36 volt) forklift.. Your videos make me look like a hero for a new guy compared to the other guys in the shop. They come to me for advice when they have problems. I owe it all to you Paul. I wish I found you when I was in automotive. You would of made me look like a hero compared to our tech support idiots. Keep up the great content that you produce and God bless you and family. By the way..... tell your brother to start producing videos... I miss him and his approach to tackling problems. .

Great educational video Danner. Always a pleasure to watch. It's great to mention that before switching the computer to check for a shorted coil or wire. I once put a new computer to a Ford fusion that had a shorted coil. They put in all new coils and it was still misfiring. I changed the computer, worked great, charged him for a diag and new PCM, and went on my way. The next day the client called me pissed off that the computer didn't work. I returned and I saw that the client put in the original shorted coils back in and returned the new coils and got his money back. HUH? I put in another new computer and coil and charged him again, but collected the money up front.

[@ScannerDanner]

Lesson learned for him! Smh, some people man

[@DooMHaMMeR247]

I'm surprised you didn't use a current clamp to see the driver not grounding that circuit. Also surprised you didn't give the circuit a ground to see it spark happen when give it a ground. Love you videos you brought me up in this field 🙌

[@ScannerDanner]

yeah, I could have showed that too and it would have been a real good test from the fuse (damn, missed opportunity there for sure). As for the giving it a ground test, I've never been able to make ignition coils fire manually. Not 100% sure why. Some type of capacitance issue with the jumper wire, compared to a transistor circuit.

[@MR.KNOWITALL1982]

@@ScannerDanner Hi Teach!! The coil turn-off is super important for how the coil produces spark. That is why you can't fire a coil "manually". great video!!:)

[@spelunkerd]

This was really helpful. I never noticed, this design invites the ground side of the primary coil straight back into the PCM. So, if you have a bad plug you'll get an unexpected spike of voltage feeding right back into the computer. This audacious design opens the door to HUGE voltage spikes straight back into the PCM, defining the path to the crusher for vehicles as they age. Small wonder that more conventional designs put the transistor onto the coil, so the whole unit can be swapped out easily, and the PCM driver is protected.

No worries, Paul - I need all the review material I can get, because I just can't get certain things to stick! The older I get, the worse my memory retention gets. When I was 17, I used to soak this stuff up like a sponge and it would stick for life. Now everything has been turned on its head from those days with computers & fuel injection, and then OBD-II later on. Just like starting over again! That's how it feels for me at least. One day I'll get so frustrated I want to quit all of it, then the next, I T-pin a ground wire at an ignition plug and get an '04 Yukon running in minutes - it hadn't run in over a month! Roller coaster of my life, lol. Win some, lose many! LOL. Anyway, hope you guys all had a great Thanksgiving together, and have a Merry Christmas as well.

My cell phone has a FLIR camera inbuilt, it is such a great tool for finding faults on vehicles, right down to parasitic current draw, it enables getting right down to the heat output of individual wires to find circuits that are staying live.

[@djosbun]

Hello Paul, I've heard you explain this in the past but if you don't mind, I'd like a little refresher on why you SHOULD use an incandescent test light and why an LED test light SHOULD NOT be used when testing ECU circuits? Is it because the ECU has the transistor inside? Is it due to the amp draw of the LED test light being too high (although I would think it draws less amos than an incandescent test light)? Thank you for your reply, Paul. You're THE ABSOLUTE best teacher I've ever had the pleasure of knowing (even better than my college Micro Economics II teacher, and he was superb)!

[@scientist100]

Higher resistance on the winding for incandescent test lights.

[@djosbun]

@@scientist100 Thank you!

[@ScannerDanner]

There are times for both. As for this video and why you must use an incandescent light: 1. The secondary KV that was jumping to my light when performing the cylinder drop test, would absolutely fry an LED test light 2. The coil control test, where we watched the light flicker, this too may cook and LED type bulb and/or test results can be misleading. To be honest, LED test lights have very little use and value when troubleshooting because of their inaccuracy and when I do use them, it is never during circuit testing, only to trigger low voltage circuits (like and ignition coil trigger signal on a COP)

[@djosbun]

@@ScannerDanner Thank you for the detailed explanation, Paul. I hope the family and Caleb's baby are doing well!

[@2secondslater]

It is a good idea to have a bit of knowledge about the load capacity of the transistors when it comes to testing transistor switched circuits in control units using test lights. A bulb type test lamp can blow up transistors.

[@throttlebottle5906]

I have seen spark on one terminal of a coil pair before, although it was pretty weak. it still fired enough to not set codes on that cylinder. seems to me it was always the ford 3.0L v6 in the aerostar, maybe because people abused them to death.

[@707061756c69]

Paul, just as a detail, it seems that the coil naming is based on firing order: 1+ companion cylinder = coil A, 4 + companion = coil B and 2+companion = coil C

I've got to get me one of those thermal imaging cameras. I don't know if you saw it Paul but Ivan from Pine Hollow recently did a video on a PT Cruiser and he used one of those to find a loose terminal issue. Looks like some of the cheaper ones run around 300 bucks.

[@hichamsaid9472]

thank you so much, does a computer cut off the control from the coil and injector when they are a mecanical problem like a sticking valve ?

[@ScannerDanner]

yes but only the injector, never the ignition coil. And it typically has to be a constant misfire for the injector to be shut off. It also needs to be a properly identified cylinder. So a random misfire code and issue would not result in an injector shut-down condition.

[@FILMINGLOL]

I was wondering since the vehicle shut down corresponding injectors on a ignition misfire will the oxygen sensors sense that dead air on those dead cylinders and make the fuel trims more positive because of the lean condition or does computer go into open loop because of misfire and disregard oxygen sensor data all together?

[@bartsarton2212]

Great question! Lambros asked that too. I want to know!

[@williamGSXR110]

I had a 2012 Focus where a slightly damaged flexplate cause a cylinder 1 intentional shutdown with a P0351.

[@geertvandenelsen6585]

Hi Paul, Great video, again! What I was thinking to eliminate a faulty coil B is to connect an wire to the negative side of the battery and with the other side at the driver side using the t-pin. As you already had an t-pin on the driver of the PCM. Disconnect the plugwires and make an, let's say, u wire with an opening in the middle on the coil. By tapping the wire, for a short period of time, you should see the coil fire right? Just an thought to try to prove that the coil B is functioning. That is an possible test with this disigned system right? Would like to hear you thoughts about this. Have a great weekend and kind regards from The Netherlands

[@ghost1225081]

Real cool on thermal imager

[@ALZWE-LIBYAN-CAR-ELECTRICIAN]

That's nice. You said (Don't see ignition coils being shut down intentionally). I see it before in Mercedes Benz W210 M111 engine. It had 2 waste spark ignition coils. Ignition coil for cylinder 2 & 3 just firing while starting Some seconds then shut down, but when I cranking the engine no compression in one cylinder, which is cylinder 3,so the ME (mercedes Benz ECM or PCM) Shut down ignition coil for 2 and 3, there is no problem in cylinder 2 just waste spark ignition system grind them hahaha. But I don't inspect in that time there is a pulse to injector or no. You talk about Nissan, Some of them when it had a timing misalignment shut down a coil intentionally waste or cop.

[@ScannerDanner]

For sure there are scenarios where we shut down ignition systems. I should have specified, that catalyst protection (which is what we are doing when shutting injectors down), cannot be achieved by shutting down an ignition coil in the same manner as you'd have raw fuel entering the exhaust.

[@xj31]

Great video, as usual. I just had a similar situation on a 2010 Jeep Wrangler with the old 3.8. 2 dead holes and the same thing, PCM not firing the coil and I used the old Verus Edge to verify the PCM failed. Same thing, flat 14 volts on the control circuit. Forgot about the test light trick, though.

[@jeromesmith3407]

Great video! What thermal imaging camera are you using?

[@Lambros_Stefaneas]

Another great video from you, SD .Learned something again. I have a question. When the ECM ,shut down the injector or injectors due to a problem as in this case, what happening with the short and long fuel trims?I can understand that the oxygen sensor will " sniff " more air (because the misfire cylinders will 'pump ' air to the exhaust system)in the exhaust, but it will spray more fuel in the healthy cylinders,trying to 'correct, what the lambda sensor reads?

[@bartsarton2212]

Great question! I believe you are correct, but let's see what the master says.

[@Lambros_Stefaneas]

@@bartsarton2212 Thanks Bart. I am waiting for the master ,to tell us/teach us ,what is happening in this case.

[@ScannerDanner]

From what I've seen, STFT will go to 0% corrections during the intentional shut-down period. So basically, a forced open loop condition.

[@thetinpin]

Out of curiosity, would the "injector fault" pid(s) be set as true while the intentional injector shutdown is active? Or is the ECM smart enough to leave that false? I wouldn't rely on that pid for diagnostics, I'm just curious. Great video my man!

[@solomonkeyn7628]

Hi Paul, great video. Please tell me about the light bulb in your test light.

[@ScannerDanner]

It is simply an incandescent filament style bulb, which is absolute required for this type of testing

[@solomonkeyn7628]

12v, 3w, 250 mA?

[@iozel4633]

Hi Paul, thanks as always for the video... A question: In the scenario where the injector is firing but no spark; I'm wondering why u said that would make the o2-2 indicate rich... cos I'm thinking if that fuel is not burning it should still cause a lean? ... or does the fuel burn in the cat cos it's hot? - Thanks :)

[@ScannerDanner]

First, I think this test is more valuable when you have an intermittent misfire. Second, the fuel that enters the cat, will deplete the cat of oxygen (a burn takes place) and this results in very little, if any remaining oxygen, so your O2 signal voltage will be high, not low

@@travisdore457 if you have immobilizer issues, you should have a code for that

I have a ford f150 4.2 liter engine It doesn’t start unless you are pressing the accelerator pedal down but dies as soon as you let up on the pedal

Not enough data to help

@@ScannerDanner 2001 f150 4.2 Truck will not start until the accelerator pedal is pressed and held all the way down but it will die as soon as you let off the pedal. . No codes.

​@user-ls6il5rt7p what is your ECT temperature on scan data with the engine cold? What is your fuel pressure? Does this 01 have a fuel psi regulator or damper on the fuel rail? Pull the vacuum hose off of it and see if there is fuel running out when you start it

Q: In waste spark ignition coil you can feed it by B+ and connect a test light to GND then touch the other pin for ignition to firing. And can do this to COP with 3 or 4 pins which is transistor inside it by connect test light to B+. Such As this from my channel kzbin.info/www/bejne/bYrGinuNo9-AZtU Why I can't do it with COP with 2 pins which is transistor in PCM? When I feed ignition coil COP 2 pins by B+ and connect my test light to GND then touch the other pin for COP, ignition coil didn't fire.???

[@ScannerDanner]

Because the ones you are able to fire, have the ignition coil driver as part of the coil and you are actually being the transistor trigger signal. On the ignition coils where the transistor is external to the coil, you'll never be able to manually fire them.

Thank you! Acts 4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.

Ok

[@ironcross420]

Why Ford why, seeing more trucks with leaking spark under 10k on the clock... Owner wont take to dealer warranty and no CEL. Got video of it.

they have intentional coil shut downs but theyll shut down the injector too.
