DTC P0341: Camshaft Position (CMP) Sensor and Crankshaft Position (CKP) Sensor Incorrect Phase Detected




General Description
The camshaft position (CMP) sensor detects the intake camshaft timing and sends pulsing signals to the engine control module (ECM)/powertrain control module (PCM). The ECM/PCM determines the advance or the retard of the camshaft timing according to the signals from the crankshaft position (CKP) sensor and the CMP sensor. If the pulse deviates from a set range over a set time while the variable valve timing control (VTC) is not activated, or the timing of the camshaft deviates from a set range over a set time while the engine is running with the VTC activated, a malfunction is detected and a DTC is stored.




Monitor Execution, Sequence, Duration, DTC Type, OBD Status




Enable Conditions

Malfunction Threshold
VTC OFF
- The gap between the position of the CMP sensor pulse and the median of the CMP sensor assembly is 10 ° or more for at least 5 seconds.

Engine running, VTC active
- The timing of the camshaft is out of the specified range (other than when BTDC is between 10 - 100 °) for at least 5 seconds.

Driving Pattern
1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on.
2. Drive the vehicle at a steady speed between 19 - 38 mph (30 - 60 km/h) for at least 10 minutes.

- Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for illuminating the MIL
When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the ECM/PCM memory.

Conditions for clearing the MIL
The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.
