Camshaft Position Sensor: Description and Operation
General Description
Camshaft Position (CMP) Sensor
Camshaft Position (CMP) Sensor
The camshaft position (CMP) sensor is located on the timing cover behind the water pump near the camshaft sprocket. The CMP sensor contains a Hall
effect switch. A magnet, mounted on the camshaft sprocket, activates the Hall effect switch in the CMP sensor. When activated, the Hall effect switch
pulls the CMP signal voltage low. The ICM interprets the low voltage as a CMP Sensor signal. The CMP Sensor signal is created as piston #1 is
approximately 25 degrees after top dead center on the power stroke. The ICM passes the CMP signal to the PCM for true Sequential Fuel Injection.
