P0341









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

CONDITIONS FOR SETTING THE DTC
The following conditions will set the DTC:

^ The engine running.
^ The cam sensor reference pulse Is not detected at the correct interval.

ACTION TAKEN WHEN THE DTC SETS
The VCM will turn on the MIL (Malfunction Indicator Lamp) after 2 consecutive test failures.

CONDITIONS FOR CLEARING THE MIL/DTC
The VCM turns the MIL off after 3 consecutive driving trips without a fault condition present. A history DTC will clear if no fault conditions have been detected for 40 warm-up cycles (coolant temperature has risen 40°F from the start-up coolant temperature and the engine coolant temperature exceeds 160°F during that same ignition cycle) or the scan tool clearing feature has been used.

DIAGNOSTIC AIDS
A poor connection, rubbed through wire insulation, or a wire that is broken inside the insulation may cause an intermittent.

Thoroughly check any circuitry, that is suspected as causing the intermittent complaint, for the following conditions:

^ 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.

Refer to Carbon Particle Removal from Evaporative Emissions (EVAP) System before starting repairs.

TEST DESCRIPTION
The step number below refers to the step number in the diagnostic table.

2. This step determines if DTC P0341 is the result of a hard failure or an intermittent condition.
