Advanced Diagnostics - DTC P0341: Camshaft Position (CMP) Sensor A And Crankshaft Position (CKP) Sensor Incorrect Phase DetectedGeneral Description
Camshaft position (CMP) sensor A detects the intake camshaft timing and sends pulsing signals to the powertrain control module (PCM). The PCM determines the advance or the retard of the camshaft timing according to the signals from the crankshaft position (CKP) sensor and CMP sensor A. If the pulse deviates from a set range over a specified time period while the variable valve timing control (VTC) is not activated, the PCM detects a malfunction and stores a DTC.

Enable Conditions
Malfunction Threshold
The gap between the timing of the CMP sensor A pulse and the middle of the CMP sensor A assembly is 10 ° or more for at least 4.0 seconds.
Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- CMP sensor A poor installation
- Intake camshaft or timing belt poor installation
- CMP sensor A failure
- VTC actuator failure
- PCM internal circuit failure
Confirmation Procedure
With the HDS
None.
With the Driving Pattern
Start the engine, and let it idle. When the diagnosis does not finish, allow the engine cool to an engine coolant temperature of ambient temperature, then restart the engine, and let it idle.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
