Camshaft Position Sensor: Description and Operation

OPERATION




- The camshaft position sensor senses the top dead center on compression stroke of the No.1 converts it into a pulse signal and inputs it to the engine control module, which then controls the fuel injection sequence, etc. based on the input signal.




- Power to the camshaft position sensor is supplied from the MFI relay and is grounded to the body. The camshaft position sensor generates a pulse signal as it repeatedly connects and disconnects between 5 V voltage supplied from the engine control module and ground.
