Camshaft Position Sensor: Description and Operation

PURPOSE

The Camshaft Position (CMP) sensor provides camshaft rotational location information to Powertrain Control Module (PCM). 

OPERATION

The camshaft position sensor is a variable reluctance sensor that is triggered by the high point mark on the camshaft. The PCM uses the camshaft
position signal for sequencing the ignition coils. The PCM also uses the CMP signal for fuel injector synchronization.
