How does the ignition module and crank sensor work?
The ignition module now starts to activate the coil packs. During engine cranking, only the Right side spark plugs (exhaust manifold side of the engine) are fired. Once the engine starts, the PCM now commands the ICM to fire both coil packs through the Dual Plug Inhibit (DPI) circuit (circuit 6 of the ICM Top Connector), .
How can I test my ignition control module?
You can test for overheating while the car still runs. Idle the engine for 30 minutes, and then tap the module with a screwdriver. The car may stall, which would strongly suggest that ignition control module may be the cause of the overheating you’re experiencing.
Where are the connectors on the ignition module?
The ignition control module has two connectors. Looking down at the ignition module (with the ignition module still bolted to the intake manifold), you’ll notice that the ignition control module has a top connector and a bottom connector. In the pin out charts below is a brief job description of what each wire does.
How does the ignition module work on a 2.3L engine?
The ignition module is tasked with activating the two ignition coil packs that feed the 8 spark plugs that the 2.3L 4 cylinder engine is equipped with. Now, I won’t go into minute technical detail as to how everything works in this ignition system. Just the basics that you and I need to get to the bottom of the problem.
When is the ignition module not at fault?
NOTE: If you have no spark from any other towers that are not ‘Paired’ (like No Spark from Cyl #1 and #3), then the ignition control module is not at fault and this tutorial won’t help you. Once you have found out which coil pack and which 2 of its towers are not firing spark, choose from one of the following CASES below.
