Camshaft Position Sensor: Description and Operation

Camshaft Position (CMP) Sensor
The CMP sensor senses the camshaft position sensor on compression stroke of the No.1 and No.4 cylinders, converts it into a pulse signal, and inputs it to the ECM. The ECM then computes the fuel injection sequence, etc. based on the input signal.
