Camshaft Position Sensor (Except 3.4L)

The Camshaft Position (CMP) sensor utilizes a Hall Effect sensor that serves a similar function as Crankshaft Position (CKP) sensor. CMP sensor is mounted in distributor or on engine block in close proximity to camshaft. On 2.2L, primary function of CMP sensor is to correlate crankshaft to camshaft position so PCM can determine which cylinder is ready to be fueled by fuel injector. On all others, CMP sensor creates a 1X signal and is used by PCM to identify which cylinder(s) are misfiring. The 1X signal will not affect driveability.
