DTC P0341: Camshaft Position Sensor Circuit Performance: Description

The Camshaft Position (CMP) sensor is a sensor designed to detect changes in a magnetic field. The control module supplies the CMP sensor with the following circuits:

• A 12-volt reference circuit.
• A low reference circuit.
• A signal circuit.

The CMP sensor produces a magnetic field whenever the ignition is ON. The CMP sensor is mounted near a reluctor wheel that is attached to the distributor shaft. When the distributor shaft rotates, and the reluctor wheel tooth passes by the CMP sensor, there is a change in the magnetic field. The CMP sensor converts each change in the magnetic field into a PULSE. If the PCM does not detect the CMP signal while the engine is running, DTC P0341 will set.
