Camshaft Position Sensor
Camshaft Sprocket
OPERATION
The camshaft position sensor 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. Four crankshaft pulses follow each group of camshaft pulses.
