Camshaft Position (CMP) Sensor

CMP sensor utilizes a Hall Effect sensor that serves a similar function as Crankshaft Position (CKP) sensor. CMP sensor is mounted inside distributor. CMP sensor creates a 1X signal and is used by PCM/VCM to identify which cylinder(s) are misfiring. The 1X signal will not affect driveability.
