Why is my coil on plug not working?

Why is my coil on plug not working?

You got No Signal at one Coil-On-Plug ignition coil The most common cause is an open in the Triggering Signal Circuit of that specific coil. You got No Signal at any of the Coil-On-Plug ignition coils The most likely cause is the crankshaft position sensor is defective.

Where is the ignition module on a wire COP Coil?

Each individual ignition coil on this Coil-On-Plug system has an Ignition Control Module located in it. This ignition module is usually referred to as the Transistor. Each Transistor (within the each ignition coil) needs this Triggering Signal to know the exact time to make the ignition coil spark.

Why is there no signal on my Wire cop coils?

You got No Signal at any of the Coil-On-Plug ignition coils The most likely cause is the crankshaft position sensor is defective. Again, this is usually the most common cause. Or the ECM (Fuel Injection Computer) is bad. Very rare, but it does happen.

Where is the crank sensor on the ignition module?

The crank sensor starts to produce and send its crank signal to the ignition module. The crank sensor signal is received on the wires labeled with the number 3 and number 4. The crank signal is an A/C voltage signal that you can measure with a multimeter in A/C Volts or with an Oscilloscope.

What are pins 1-2-3 on a Montero?

Pins 1-2-3 are low voltage driver signal to the ignition module… the PCM sends a low voltage, between 300mV and 3V -maximum-, which is used to trigger the transistor in the ignition module for each ground driver; the ignition module then fires the ground which charges the coil, and when it releases the coil fires.

How to reset the engine control module with no hassle?

Disconnect the battery and Switch the ignition key to the on position for about 15 minutes should reset the ECU Can a ECU be reset? Yes, all ECU (Engine Control units) can be reset and be should reset once per manufacturer’s guideline for a smooth relearn process or upon installing a replacement unit. How do I reset my Ford PCM?

How to reset the engine control module ( ECU )?

The 2 most common ways to reset your car computer is by either unplugging the battery or by resetting the fuse related to the engine control module Will disconnecting battery reset ECU? Disconnect the battery and Switch the ignition key to the on position for about 15 minutes should reset the ECU

What causes a Montero Sport to lose power?

Second if there is a cam/crank mismatch either due to a dirty signal from either sensor or a jumped timing belt, the same scenario will occur as a faulty cam sensor… again the symptoms are not consistent with your only losing spark on one coil and not two or three however.

Can you test a coil on plug ignition coil?

And as you have already deduced, if this Triggering Signal is not present the Coil-On-Plug ignition coil will not spark. This signal CAN NOT be tested with an LED or a test light. Only an oscilloscope or a Digital Multimeter (with the capability of reading Hertz Frequency) can be used.

Do you need 3 wire cop coils for ignition?

As mentioned all along in this article, this info applies to any vehicle that has a Coil-On-Plug ignition system with three wires in the connector of each individual coil. The following articles (within this site) will shed some more light on ignition systems.
