This is an open circuit test procedure using a test light and a voltmeter. Just some simple tools and knowledge of the circuit is needed. Also the procedures shown in this video can be applied to ANY ground side switched circuit.
This video was taken from a 5 part training series I did for my students on various ways to identify a misfire and restricted exhaust testing. You can find this 5 part series here
www.scannerdanner.com/scanner...
For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.

Thanks for the great info! I have a injector wiring issue on my 2007 jeep wrangler. I have a cylinder #4 misfire. Its reading 14.0 -14.1 only on #4 cylinder. 1,2 3,5 and 6 injectors read 13.6 -13.8 and never reach 14.0. Where could my problem be?

Do you know of a great mechanic in the 92336 zip code area. I am in Southern California. I have a 2000 Ford mustang v6 with a crank no start, no spark. I have checked about everything, I think, and I am thinking it probably something simple that I am missing. Any help appreciated ¹

Thanks I just found out what the problem was thanks to your video on crankshaft sensor. I was getting no spark on ignition coil pack but did have voltage on the connector. So checked voltage on the fuel injector with a light probe. The control side was no lighting the probe when I cranked the engine. So I checked the crankshaft sensor by the harmonic balancer. As I was checking the connection, I noticed the teeth weren't underneath the crankshaft sensor and the belt seemed off. After further inspecting the harmonic balancer I notice it was coming out which got the teeth to not be underneath the crankshaft sensor. The bolt holding the harmonic balancer had broken off and balancer was coming off.

Paul, thanks for showing that, it is good info. Perhaps you should have explained how the injector circuits work, as i think that not many do understand. I'm a Chrysler dealer tech, and the way Chrysler designed their systems, the injectors get 12v all the time, the pcm turns the ground on/off to turn the injectors on/off. I don't know atm how all the other manufacturers design their injector circuits, but wanted to point that out in the event that there are different designs.

Great video on a simple open. This is the kind of stuff that takes maintenance skills to the next level separating the real wrenches from the parts changers. If you want to be a great mechanic who has families sending everyone they know to you and their kids and so on....Be like Paul Danner. He fixed this cat's ride for a fraction of the cost of the computer swap the guy before him did. This customer will be back again for honest service. Paul, keep up the great work, you are setting the example and helping make a good name for the trade.

Awesome instructional video, thank you for making it and sharing it. I had just completed the dreaded plenum plate and gasket repair on a Dodge 5.2, along with numerous other repairs and replacements while in there. I had one cracked fuel injector, so I bought a new one to replace it. It was a BWD (Borg Warner). Got everything put back together, and it was running like complete shit, bad idle, wanting do die, missing, etc. The computer finally kicked a code, P0208, which was the same cylinder that had the brand new injector. Found this video doing research, planning for the worst, even a possible broken valve spring. Well I checked the resistance on that injector, and there was none. Brand new, non working injector. Just replaced it and my truck is running the best it has since I've owned it! Lesson to be learned, don't ever count on brand new parts to be in working condition! Anyways, thanks again for the video!

If the plastic of the wires going to the injector plug is cracked open but not touching each other or the ground(Body of engine) could this still cause a small misfire during a cold idle? When I say small misfire I mean a misfire that does not register on the ECU of vehicle just like a slight stumble as if an injector gave too much or too little fuel.

Very informative, just one point, it took me a couple of times watching your test at the engine computer to understand what you were doing. Sometimes us DIY’rs who are still learning need the information fully explained to us , step by step. I finally figured out the test results at the computer, when I broke it down to a simple electrical circuit. Just my 2 cents. Excellent video none the less. You are a great human being, helping the average person to diagnose and fix their own car. God bless.

Good Afternoon Paul Danner and happy blessed Friday 🙏. I have a (2003 Dodge Caravan SE V6 3.3) and its throwing 2 codes (P1684-Battery Was Disconnected) & (P0201-Injector #1 Control Circuit). I have the 2003 powertrain diagnostic procedures book for the code (P0201-Injector #1 Control Circuit) and I have the 2003 Transmission Diagnostic Procedures book for code (P1684-Battery Was Disconnected.) I have taken action and followed instructions from the book that gives procedures for code (P0201) and i applied Test#1 & Test #2. Im on Test #3 now and these are the instructions..... Turn the ignition off. Disconnect the Fuel Injector harness connector. Remove the ASD Relay from the IPM. Turn the ignition on. Jumper the Fused B+ circuit and the ASD Relay Output circuit in the IPM. Using a 12-volt test light connected to ground, probe the (K342) ASD Relay Output circuit. Does the test light illuminate brightly? Yes➡️➡️➡️ Go To 4 No ➡️➡️➡️ Repair the open in the (K342) ASD Relay Output circuit. Perform POWERTRAIN VERIFICATION TEST VER-5. Im not grasping and understanding these instructions as to where i can apply it and take action doing test steps from the book. Are you able to help me grasp and understand this procedure of Test #3? Test #2 procedure from the book for code (P0201) i applied the procedure and i filmed myself applying it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-r7xmOt0ueGk.html

There is no excuse however if the employe of the shop doesn't pushes tech to be professionals and if he grooms them to just be Parts changers then this is what happens a real mechanic knows exactly how things work and knows exactly how to troubleshoot there's a big difference from people who just throw Parts at something and people who actually know what's going on this is one of the reasons why I got out of the trade when I was in the trade there was no respect for people who knew what they were doing it there was a lot of respect for people who change Parts because people will change Parts make the shop money there's a fine line there and business owners need to learn how to walk that line good job with this video I appreciate you showing how some simple steps when troubleshooting can resolve head-scratching problems I repaired a similar problem last night on a friend's car it's been 17 years since I put my hands under a hood yet I knew exactly where to look because I have the same attitude as you you don't always need to have all these fancy tools you just need to have some common sense and some troubleshooting skills

To find an open or a short in a wire, Power Probe's circuit tracer works well. It is unique in that it switches from tracing E field (voltage, open wire) or H field (current, loaded or shorted wire) as needed and LED even indicate direction of current flow. No, I don't work for PP, I'm just a satisfied customer.

@Turbotomass
@Turbotomass 9 лет назад
***** another thing to keep in mind is that the computer will not control the injector with a misfire or fault. Obviously not the case here as there should be 12v to the PCM. Me personally have spent good money on diagnostic equipment. Granted in this circumstance you don't need fancy tools. To do diagnostics and not have advanced tooling doesn't make any sense. You can't make "100% calls".

I have a 350z...has P0304 misfire code. I switched the coils, plugs, injectors around. No change in misfire code. When I tore the engine down I found the factory fuel injection harness had butt connections instead of an actual factory plug. I'm guessing it's the wire harness. The VQ35de engine has the injectors hidden under the plenum. So it's gonna be difficult to run this test. I'm just gonna throw a $185 wiring harness on it and hope for the best. Thanks for this video. It made me confident this is the problem I'm having

The voltmeter won't be the best tool for testing the computer driver. Use a test light

Hey ScannerDanner! I’m trying to diagnose my own vehicle and would love some insight Cyl 4 misfire, ignition is good but it looks like no fuel is getting to that cylinder, swapped out injectors and moved them around and still at cylinder 4. The spark plugs were replaced and you can tell that the 4th cyl plug looks brand new still. So, this leads me to think there is an open circuit somewhere between the ecm and the fuel harness, what would you do in my position?

Great video thanks . I have a car that the #8 injector has no pulse . I was told the computer was bad . I took apart the engine compartment to fix other issues and there are several areas of exposed wires . I don't visually see any breaks. My question is my ecu has hundreds of pins ( connectors ) in the plug . Do one of those pins go to that injector ? I'm gonna start tracing tommorow. Can I test the circuit by conning one of the pins to the connecter ? This would help me before I spend 1500 on new ECU and flashing . Mike

superb video dan, i just want to ask a question. suppose that there is not pulse in first cylinder injector, then is that possible that there will be not current in ignition coil of 1st cylinder?

My name is Paul Danner 😉 Symptoms dictate the answer! Is your question about a single cylinder misfire, or a complete no start? You can have spark and no injector pulse, you can have injector pulse with no spark, you can have no spark and no injector pulse! All dictated by design differences and what the fault is, from car to car.

Shalom brother. Is it possible for a PCM to cause an intermittent bad injector driver problem? Or it could be more likely to be intermittent wiring problem?

I'm also considering buying a second hand solus pro. They are very cheap here in UK.

Funny thing is that the guy who sold the scope to me said that he doesn't need it anymore as he bought a scanner now?! ;)

I didn't leave you with a cliffhanger here. No reason to get upset. I've had this paid channel for over a year now yet i still give out free and valuable information here for nothing. What I offer on my paid channel is college level training for next to nothing. You don't have to subscribe, no one is forcing you. And then because you're pissed off you leave some b.s. comment about my brother?

quick question re test light - do they have to be computer safe? Will a 6-12V tester be any good for testing the 5V side of sensors?
