Ignition control module

Does anybody no were ignition control module is located on 02 jeep Cherokee 4.0 inline Choctaw

I looked up that part: "Ignition Control Module" and there is nothing listed as a replacement part. But I do know there are several key components that are necessary to make an ignition spark. Your ECM controls the spark and timing. That depends on the Camshaft Position Sensor where the distributor used to be. Also the Crankshaft Position Sensor located on the bell housing picking up a signal from the rotating flywheel. And there's the Coil Pack that is a row of coils mounted directly on the spark plugs. All of those together make the spark. The one that fails most commonly is the Crankshaft Position Sensor, you will get a code P0320. A code P0340 is failure of the Camshaft Position Sensor. And so on. Good Luck.
