DTC P0341 Camshaft Position (CMP) Sensor Performance

Circuit Description

The camshaft position (CMP) sensor is installed on the cylinder head at the rear of the camshaft gear. The CMP sensor detects total of five projections per one engine cycle (four projections arranged equally every 90° and one reference projection on the camshaft gear surface). The ECM monitors both crankshaft position (CKP) sensor and CMP sensor signal pulses to ensure they correlate with each other. If the ECM receives extra or missing CMP sensor signal pulse this DTC will set.

Condition for Running the DTC

^ DTCs P0340 P0642 and P0643 are not set.
^ The battery voltage is between 10 to 16 volts.
^ The ignition switch is ON.
^ The CMP sensor signal pulse is detected.

Condition for Setting the DTC

^ The ECM detects extra or missing CMP sensor signal pulses during engine 50 rotations.

Action Taken When the DTC Sets

^ The ECM illuminates the MIL on the second consecutive driving cycle when the diagnostic runs and fails. Refer to DTC Type Definitions for Action Taken When the DTC Sets - Type B.

Condition for Clearing the DTC

^ Refer to DTC Type Definitions for Condition for Clearing the MIL/DTC - Type B.

Diagnostic Aids

^ If an intermittent condition is suspected refer to Intermittent Conditions in this section.
^ Electromagnetic interference in the CMP sensor circuits may set this DTC.
^ An intermittent CMP sensor signal pulse may set this DTC.
^ Ensure the sensor is tight and the camshaft gear projections are not damaged.
