Camshaft Position Sensor: Description and Operation
CAMSHAFT POSITION (CMP) SENSOR
The CMP sensor is also a magneto resistive sensor, with the same type of circuits as the CKP sensor. The CMP sensor signal is a digital ON/OFF
pulse, output once per revolution of the camshaft. The CMP sensor information is used by the PCM to determine the position of the valve train relative
to the CKP.
