P0341

Camshaft Position Sensor Circuit:

CIRCUIT DESCRIPTION
This DTC will cause the cam/crank relationship to be skewed and cam pulses will be in a haphazard ratio to crank pulses. This fault is not a solid or consistent failure and may not act the same way twice. DTC PO341 is a type "B" DTC.

DTC P0341 WILL SET WHEN
With engine running, the cam sensor reference pulse is not detected at the correct interval.

ACTION TAKEN (VCM-A WILL DEFAULT TO)
The Vehicle Control Module-A (VCM-A) will turn "ON" the MIL (Service Engine Soon) after 2 consecutive test failures.


DTC PO341 WILL CLEAR WHEN
The VCM-A will turn the MIL "OFF" after three consecutive trips without a fault condition present. A history DTC will be cleared if no fault conditions have been detected for forty warm-up cycles [coolant temperature has risen 22°C (40°F) from start-up coolant temperature and engine coolant temperature exceeds 71°C (160°F) that same ignition cycle] or the Tech 1 clearing feature has been used.

DIAGNOSTIC AIDS
An intermittent problem may be caused by a poor connection, rubbed through wire insulation, or a wire that is broken inside the insulation.

Any circuitry, that is suspected as causing the intermittent complaint, should be thoroughly checked for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal to wiring connections or physical damage to the wiring harness.

Refer to Intermittents. - Intermittent Malfunctions

Important
^ Before clearing DTC's use scan tool to record freeze frame and failure records for reference, as data will be lost when "clear info" function is used.

^ Check for intermittent short to voltage or Electromagnetic Interference (EMI) such as wires run along side spark plug wires or high power transmitters (like mobile radios operating in the vicinity) or cam sensor wires.
