Camshaft Position Sensor

Print

Description & Operation



The Camshaft Position (CMP) sensor contains a Hall-effect device that provides cylinder identification to the Powertrain Control Module (PCM). The sensor generates pulses as groups of notches on the camshaft sprocket pass underneath it. The PCM keeps track of crankshaft rotation and identifies each cylinder by the pulses generated by the notches on the camshaft sprocket.
