Camshaft Position Sensor: Description and Operation
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 Camshaft (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.
