Camshaft Position (CMP) Sensor

EEC-V uses 2 types of CMP sensors. A variable reluctance sensor is used.

CMP sensor is used to determine the position of the camshaft and to identify when piston No. 1 is at TDC of compression stroke. CMP sensor provides cylinder identification information during engine start-up for PCM to initiate correct firing order. Cylinder identification information signal is sent from CMP sensor to PCM through CID circuit.
