Camshaft Position Sensor: Description and Operation
Camshaft Position (CMP) Sensor
The Camshaft Position (CMP) sensor is located at the rear of the cylinder head. The PCM uses the CMP sensor in order to distinguish individual
cylinders and monitor engine misfire. The CMP sensor is not adjustable.
Operation
The Camshaft Position (CMP) sensor (4) contains a signal generator (hall switch) (3). A camshaft signal rotor (1) is press fit onto the camshaft (2).
The CMP sensor has a specified air gap between the sensor core end and the camshaft signal rotor. A digital signal is generated by the CMP sensor
when the signal rotor turns. The CMP sensor's digital signal is sent to the Powertrain Control Module (PCM).
