The camshaft position sensor (CMP) is used to indicate camshaft position so that the powertrain control module (PCM) can determine which cylinder is misfiring when misfire is present. If the PCM receives an intermittent signal from the CMP, then the CMP Resync Counter will increment. In order to seat a DTC, the PCM must see a minimum number of resync's within a maximum time.

The malfunction indicator lamp (MIL) will illuminate.

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.

If the PCM sees less than 15 resync's in 256 seconds, the counter is reset to 0. Anytime a poor connection is present, the Cam Sensor Reference Activity Counter will stop incrementing and the Cam Sensor Resync Counter will increment.

The numbers below refer to the step numbers on the diagnostic chart.

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

3. The counter should stop incrementing with the sensor electrical connector disconnected and set a DTC P0342 after two ignition cycles with the sensor disconnected. If it stills increments, the PCM is faulty.

4. By moving the CPS sensor electrical connector, the connections at the sensor are checked. Make sure electrical connector remains securely fastened.

5. A poor connection in any of the circuits at the CMP sensor will cause the CMP Resync Counter to increment. Anytime a poor connection is present, the Cam Sensor Reference Activity Counter will stop incrementing and the Cam Sensor Resync Counter will increment.
