Where is the ignition control module located?
Some ignition modules are mounted inside the distributor. Unplug the electrical connector from the module and remove the mounting bolts using a Phillips screwdriver or ratchet and socket.
How do I know if I have a bad ignition module?
1. Engine performance issues. One of the first symptoms of a problem with the ignition module are engine performance issues. If the ignition module fails or has any problems it can lead to performance issues with the vehicle, such as misfires, hesitation, loss of power, and even reduced fuel economy.
How do you check an ignition module?
Connect the ground lead from the 12-volt test light to the negative terminal on the ignition coil. Have your partner crank the engine over several times. Your test light should flicker on and off. If so, your module is working properly and no further testing is necessary.
What would cause an ignition control module to fail?
The cause of an ignition control module failure is often associated with age and damage from heat buildup. The correction for this issue becomes the replacement of the failed component.
What happens when the ignition module goes bad?
A faulty ignition module can affect ignition timing, resulting in an engine that misfires and runs rough. The engine may also run well at low speed, but won’t accelerate well. 3. Stalling: A failing ignition module can occasionally prevent the engine from getting spark, causing it to stall.
What causes the ignition control module to fail?
What happens when a ignition module goes bad?
Can you fix an ignition module?
You can instead have the ignition module tested at an automotive repair shop. Once you have a correct diagnosis of a failing module, you can perform the replacement yourself. If the mechanic informs you that there is a problem related to the module, but it is not the module itself, you might not need a new part.
Can you bypass the ignition control module?
This type of ignition system has the trigger signal being sent directly to the ignitor module which then fires the coil. To allow the ECU to take control of ignition timing it will “bypass” the ignitor and send the signal to the ECU for ignition timing processing.
Is there a fuse for the ignition?
Is there a fuse for the ignition? In most vehicles, the ignition relay is located in the long black box of your vehicle that you can find under the hood. The box usually has a diagram on it which will help you easily locate the ignition relay inside it once you open it up. The box is also called the fuse box.

Where is the ignition control module located in a car?
However, this electronic component is very sensitive to heat. Since many vehicle models locate their modules inside the engine compartment, it is not unusual for these components to succumb eventually. But whatever your vehicle model, follow these steps to replace the control module in your car.
Why did my Chevy Cavalier engine lose power?
The car began to lose power and would stall during driving. Dealer had the car for 21 days, and replaced the switch clusters, ignition switch, reprogrammed body control module, replaced pcm and found burnt 3-4 clutch. At 40,613 miles the engine lost power and stalled again (while on the freeway).
Is the ignition control module sensitive to heat?
The ignition control module in your vehicle controls ignition spark sequence and fires the ignition coil as well. However, this electronic component is very sensitive to heat.
How to test the ignition module on a Chevy Cavalier?
If you’ve been wondering how you can test your ignition control module (ICM) on your 2.2L Chevy Cavalier or Pontiac Sunfire? Well, you’ve come to the right place.
How to test the ignition module and crank sensor?
We’ll first check for the basics like battery voltage and engine Ground to the ignition control module (ICM).
Where is the CKP sensor on the ignition module?
As you can see, the CKP sensor signal is critical for the ECM and ignition control module to start sparking the Igntion coils at START UP and at all engine speeds. The CKP sensor is located on the block.
What is the 7x reference signal on the ignition module?
The ignition control module upon receiving this AC Volts crank signal, converts it into a DC digital signal and sends it to the ECM. This digital signal is called the 7X REFERENCE signal. The ECM, upon receiving this 7X REFERENCE signal, returns to the ignition module an Ignition Coil Control signal thru’ two different circuits.
