Camshaft Position Sensor: Description and Operation
The Camshaft Position (CMP) Sensor is also a magneto resistive sensor, with the same type of circuits as the crankshaft Position (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 crankshaft position.
