Camshaft Position Sensor: Description and Operation

OPERATION
- The camshaft position sensor senses the top dead center on compression stroke, converts it into a pulse signal and inputs it to the engine control module, which then computes the fuel injection sequence, etc. based on the input signal.
- Power to the camshaft position sensor is supplied from the multiport fuel injection relay and is grounded to the body. The camshaft position sensor generates a pulse signal as it repeatedly connects to and disconnects from the 5 V voltage supplied from the engine control module and ground.
