Timing Control Systems
WARNING: This page is about a different car, the 2002 Jeep Wrangler, 2002 Jeep Liberty, and 2002 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
Ignition timing is electronically controlled by Powertrain Control Module (PCM). Base ignition timing is not adjustable with this system. PCM controlled ignition system consists of engine coolant temperature sensor, crankshaft position sensor, distributor (2.5L), camshaft position sensor, ignition coil(s), manifold absolute pressure sensor and throttle position sensor. For ignition coil resistance test, see IGNITION COIL . For sensor testing, see ENGINE SENSORS & SWITCHES .
