Powertrain Control Module
WARNING: This page is about a different car, the 2006 Chrysler Crossfire. However, it is still accessible from the selected car via links, so may be relevant.
The PCM uses inputs from the Camshaft Position Sensor, Crankshaft Position Sensor, Knock Sensors, Engine Coolant Temperature Sensor, and MAF Sensor (3.2L engine only) to trigger the Ignition Coils. The PCM is mounted in the engine compartment within the Control Module Box.
