Camshaft Position (CMP) Sensor




The Camshaft Position (CMP) sensor is located on the timing cover behind the water pump near the camshaft sprocket. As the camshaft sprocket turns, a magnet in the sprocket activates the Hall-effect switch in the CMP sensor. When the Hall-effect switch is activated, the signal line to the PCM is grounded, pulling the CMP sensor signal circuits applied voltage low. This is interpreted as a CAM signal.




The CAM signal is created as piston #1 is on the intake stroke. If the correct CAM signal is not received by the PCM, DTC P0341 will be set.
