DTC P0341

CMP sensor range/performance malfunction

DETECTION CONDITION

• The PCM monitors the input signal from the CMP sensor while the engine is running. If the input signal from the CMP sensor does not correspond with the proper pulse number, the PCM determines CMP sensor performance malfunction.
Diagnostic support note
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• Loose CMP sensor installation bolt
• CMP sensor malfunction
• Connector or terminal malfunction
• CMP sensor pulse wheel malfunction
• Related wiring harness malfunction
• PCM malfunction
