Test Description

WARNING: This page is about a different car, the 2002 Pontiac Sunfire and 2002 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers in the diagnostic procedures.

  1. 3

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

  2. 4

    The counter should stop incrementing with the sensor electrical connector disconnected and set DTC P0340. If the counter still increments, this indicates that the PCM is malfunctioning.

  3. 5

    A poor electrical connection in any of the circuits at the CMP sensor will cause CMP resync counter to increment. Anytime a faulty electrical connection is present, CMP reference activity counter will stop incrementing and the CMP resync counter will increment.
