I appreciate all of this info in one video and with time stamps. The only part I have a different opinion on is with checking resistance. Checking for power and ground or the resistance of a wire is not a good test. It is only helpful if you understand the limitations and there is not high resistance. If you have an open circuit, then sure resistance is helpful. If there is high resistance in the circuit you would not see that unless you load tested those circuits. A single strand of wire will show good resistance and show you you voltage until they are loaded. I have found so many technicians do not understand this and continue to rely on resistance alone. I use resistance checks from time to time and I understand that if it tests good then that doesn't mean the circuit is good. It can be much quicker some times to just check resistance and if I find an open circuit then great. Just my thoughts. Otherwise this was a great video.

@AutomotiveDiagnosis Жыл бұрын

Hi there and thanks a lot for sharing your thoughts. I agree as I’ve seen many cases that the regular resistance check is not helpful if there is not open circuit. But what I’m trying to do here is at the first place, I present the recommended details from the workshop manual as this is good for the basic troubleshooting. But of course there are some other methods that I prefer to present in another videos, just to avoid any confusion. Normally I use picoscope many times but I just mentioned it here and will explain it separately. I appreciate your kind words and sharing your knowledge as this is how everyone must be.🙏🙏

@jeremiahschaefer9771 Жыл бұрын

I use resistance checks mostly to confirm that I'm on the right circuit, theirs no open or short to ground/power, or the circuits are no shorted together. Then I load the circuit once I have proven I'm on the right circuit

@19:23. The multimeter's positive probe was on the IGF terminal not the IGT terminal (i.e. trigger). The IGT can only properly be tested with engine cranking or ON. The IGF can be checked when ignition is ON (which is what you showed), engine cranking or engine ON. IGF (when ignition is ON) will show about 5V (it only switches to near 0V at the moment the coil sparks during engine cranking or engine ON).

@AutomotiveDiagnosis Жыл бұрын

Hi there, thanks for your comment and for reporting the issue. You’re correct and as we explained in the previous parts of that section, IGT must be checked when engine is running. There was an error during the video editing and it has been already rectified. Thanks 🙏

Ok at 18:49 the testing of the coil connector here are we to universally gather the connectors are numbered 1 2 3 4 as their respective pins, so is red probe as illustrated placed in pin 1 or pin 4 ? With red lead probe in the connector and black lead probe ground placed on the engine valve cover to obtain the Voltage reading am i correct or am i way off base with this ? I have some of these misfires in cylinders 4 5 and 6. I know it cannot be spark plugs they are brand new. those three coils are not brand new. So how do i rule out these 3 coils to know that the issue is with my 3 fuel injectors at that point?

Hi, how can check only coil 4 pin with multimetar, didn't see on video? Thanks

@AutomotiveDiagnosis 8 ай бұрын

Hi there, checking the 4-pin ignition coil is not as easy as 2-pin coil because it has the ignition module inside which makes the multimeter inspection very hard and normally you won’t find any specifications for 4-pin ignition coil in workshop manual. So as so did in the video, so would check the wiring, and for the coil itself, I would swap it with the ignition coil from another cylinder, so if codes moves to the new cylinder it shows that coil is faulty.

Hello, @12:38 the resistance is below 6, is the ignition coil good or bad? What is the minimal allowance of how low or high resistance can be past 6-8 kohms. Also when testing the Ignition coil ground circuit for resistance at the connector does the car need to be in On position or off?

@AutomotiveDiagnosis 9 ай бұрын

Hi there, thanks for your comment. That difference in resistance is still acceptable, normally if there is anything wrong, resistance value will be much higher or lower, this difference was only less than 1 ohm which is nothing importance. Many workshop manuals accept 15% higher or lower than recommended resistance. For the second question, ignition switch must be off.

@AutomotiveDiagnosis 5 ай бұрын

Hi there, thanks for your comment. That way we can confirm the presence of the signal (trigger), but normally we can get more from the waveform. As I explained in the video, by analysing the waveform we can check the dwell timing, pick voltage and spark duration that each one of them gives us some clue about the possible problem.

So I have a no spark issue with my car, and I couldn’t find what it was, after doing some testing I’ve come to figure out possibly that my ignition coils aren’t grounding, what could it be? I use a test light on both of the terminals on the harness, they both get ground when the ignition is off, And they both get voltage when the ignition is on. But when I go to crank, the test light doesn’t blink, indicating that it is not forcing ground when that cylinder is ready to spark. does anyone have any information for this to help me out? Did I do the test incorrectly? or does it simply not work that way?

When you have a faulty ignition coil, most likely you are able to start the engine but of course engine will run roughly. Each three wires can be checked individually for short or open circuit even if engine is off. For the ignition coil itself, the best way if to swap it with an ignition coil of another cylinder, then start the engine and check the fault codes, if misfire or ignition coil fault code moves to the this cylinder, it confirms that ignition coil is faulty.
