Camshaft Position (CMP) Sensor
The camshaft position sensor is located on the timing cover behind the water pump near the camshaft sprocket. As the camshaft sprocket turns, a magnet in it activates the Hall-Effect switch in the camshaft position sensor. When the Hall-Effect switch is activated, it grounds the signal line to the PCM, pulling the camshaft position sensor signal circuit's 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.
