Ford Parts Cannon MISFIRE (Why you NEED a Scope!)

[@victormihov7855]

This exactly happen to me at the Ford shop where I work. Error P0302 another diagnostician changed twice coils twice spark plugs and twice injectors Ford Explorer failed to fix problems and gave it to me, in a second with a scope I knew it was just PCM. There are no professionals today, they don't even know how to read English, and not thinking. I tell everyone 1000 times: You don't know what the problem is, better don't change anything, give it to someone else to fix it. Greetings from Israel. Thank you Ivan, if i visit USA, i will come to meet you for 5 minutes for coffe, i am a big FAN:)

Agreed. Scoping is a must these days. Just this Monday I had a co-worker ask me about a misfire on a Chrysler. I told him to scope all the injectors and the coils to at least rule out some preliminary fault source. He pulled the oil cap and saw oil/water mix and called a faulty engine. I knew better than this but I'm not the shop foreman. So at that point it was out of my hands. But I know he was looking for anything else it could be because scoping the related components meant not knowing what to do or how to do it. So instead of taking the opportunity to learn. Her went with a guess. The customer declined so the outcome never happened. Point being that a lot of techs still don't know how to use a scope and even if you offer to teach they're not interested.

Ford Australia when they were manufacturing cars in Australia went to a similar direct fire ignition system to what the 3.8 litre Holden/Buick V6 engine was fitted with except the 3 driver transistors were in the computer whereas GM had fitted the ignition coil driver transistor."motherboard" into the ignition coil pack. Ford started doing it that way in the mid 1990's in the EF Falcon but they reverted back to the previous distributor ignition system which was fitted into the EA-ED Falcon into the next model - the EL Falcon. Too many EF Falcon taxis were coming in for ignition coil replacement under warranty because the ignition coils got cooked underneath the inlet manifold whereas the Buick (Holden) V6 engine which was mounted in rear wheel drive configuration in the Holden VN-VY Commodores (1988-2004 models) were mounted at the front of the car where the air cooled down the ignition coils. Ford Australia decided to refit the EF Falcon ignition system into the AU Falcon in 1998 while it was a different design of car the same problem still arose - cooked ignition coils. They revised that ignition coil in the series 2 AU Falcon but I don't know if that fixed the problem,by 2000 they built the DOHC naturally aspirated &; turbocharged "Barra" 4 litre DOHC powered 4 litre BA Falcon which suffered from failing ignition coils which were the Bosch/Motorcraft "pencil" type of coil (×6) which usually failed by 100,000 kilometres or 60,000 miles. Maybe because it was a big inline six the ignition coils got too hot,I don't know but my brothers old friend fixedl his BF Falcon station wagon up by replacing all of the ignition coils & spark plugs because the engine was only running on 2 cylinders. Yes, being an electrician makes it easier to understand & find faults in an EFI car but I upset a mechanic on Quora who said that I didn't know what I was talking about when I had a P0327 knock sensor code, a P0171 & P0174 code which was the cause of the check engine symbol turning on & off in my car. I had that go out whenever I would blip the throttle because I had low fuel pressure cause the lean codes but it would only turn on at idle or low speed - it was caused by a bad fuel pressure regulator !

[@vgbr88]

Ivan, thanks for referring Jake's channel. It makes sense that someone could repair the ECM in one of these if it's a common problem and who knows - it may be as easy as replacing a transistor. It's a terrible design by Ford but then again it can be avoided with some preventive maintenance. This was one of those cases where you saw the patient and immediately knew what was wrong with him based on experience.

[@Diagnosedan]

Clear diag! Its not the fix but i would have recommend to change the coils and plugs anyway before installing the repaired pcm. I hope the owner wants to go ahead with the repair or the money on those parts was wasted.

[@PineHollowAutoDiagnostics]

Hey Dan! All new coils and plugs and 2 injectors replaced before I looked at it ;)

i agree!! put the circuit driver inside the coil assembly... and, as you say, it's only a transistor. Coil IS in a HOT ENVIRONMENT, though.

I think the right parts were changed but for the wrong reasons. If #1 coil shorted out, the others were probably not far behind and those plugs had serious miles on them. It's too bad the owner hadn't replaced those parts, say, about 20k miles ago. As usual, Ivan. Another good informative video.

Interesting. I got a 2010 MKZ from a friend mechanic who got it from a customer. it had 210k miles on it. front suspension bushing was squeaking wd40 gel lube resolved that lol. otherise car seemed fine. I immediately did plugs on it and realized they were the originals! they almost had nothing left on them! luckily no misfires however I found why no one wanted it. the torque converter was acting up. the usual bs for a ford. i downed the price to $500 assuming the tranny would have to come out eventually. I just added shudder fix which has mostly in control. fluid was recently changed by friend. I gave car to my daughter who passed it to another family member. 3 years later the thing is still going. I have no clue how or why. the original owner Im pretty sure all they did was oil changes. I assume the water pump is also ready to let go which on that engine is yeah lets water down the oil...

[@ferrumignis]

This is why pulling HT leads on a running engine to check which cylinder is misfiring is a bad idea, it really stresses the insulation within the coil and also stresses the coil driver which has to absorb all the energy from the coil.

[@jdtractorman7445]

Failures like this would not happen if people would perform the dreaded "preventative maintenance" to the vehicle. In my opinion, no vehicle will reach 100k on spark plugs. It's a commonly overstated number by vehicle manufacturers across the board. I would say 60k-70k at most for spark plugs. Also, when changing plugs, change the ignition coil boots too if they are replaceable separately. They are commonly overlooked when doing a tune up.

[@PineHollowAutoDiagnostics]

Iridium plugs will easily go 200k ;)

[@everettstilley6274]

What kind of test leads are those? They look like they are just clamping on and not actually contacting the wires.

[@theblackhand6485]

Maybe you can run the engine computer on a lower voltage (?). ...by some kind of converter or a simple resistor (?). Peak power can do destroy a lot!

[@tomtke7351]

just by your segment's title -- I'd agree that having/using an o'scope is UNAVOIDABLE. Car repair is heavily electronic and nothing is as valuable as a scope when troubleshooting such, although test lights are surprisingly valuable yet simple You repair guys (& dolls) are now electronic technicians too.

I have a friend that needs to replace an ABS module on a ford focus 2012. Does any know if the brakes need bleeding after module replacement and also does it need to be programmed to vin?

[@AT-wl9yq]

It depends on what you are replacing. The abs pump and module are bolted together on that car and you can either replace both of them as one unit, or do each individually. In most cases, both are done at the same time as one piece. Yes, you need to bleed the system, but you can't just bleed at the wheels. Air will be trapped inside the abs pump itself, so you need to have a scanner that has a service bleed function. This gets the air through the pump so you can then bleed the air out at the wheels. If your scan tool doesn't have a service bleed function, you can go into the PID's and manually open and close the valves inside the abs pump. However, unless you really know what you're doing, I wouldn't recommend doing it that way. If you are replacing the module, it has to be programmed. This is normally done by connecting a scan tool to the car before you start the job, and transfer the programming on the current module to the scan tool. Once the new unit is installed, you program it the stored data on your scan tool. If the current module is broken and can't communicate with the scan tool, you need to go to Fords website and download what's called "as built data". This is the original programming that was put on the module at the factory. Once as built data is installed on the new module, you would then update it to current software if needed.

[@Bizija123]

@@AT-wl9yq Thank you for taking the effort to let me know about this. I do have a ThinkTool mini that will do abs bleed I believe, but it's always a crapshoot with the module programming as I've seen on Ivan's videos with third party tools. Don't have the oem ford diag software of course. The old module is still functioning but the hill assist is throwing errors and abs lights on the car. The only code was U3000:48 abs control module supervision software error.

@Ivan - Excellent tutorial. The use/proper use of a scope would seem prudent and certainly definitive. Just a few questions: in lieu of a scope - (1) Continuity of coil wires to/from coil (DVM). (2) Continuity/resistance of coil itself. Isn't there a "filter", in the way of a capacitor (wouldn't a diode be best?), that prevents any errant current from going back to the computer if there's a short in the coil?

[@alf699]

Your diagnostic is 95% thorough and I am guessing that you checked the missing step without putting it on video. There is a small possibility that the signal cable at the pin of the wiring harness corroded off. By piercing the wires with the Fluke connectors, you didn't really proof it all the way to the ECM Pin.
