Test Description

WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 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 on the diagnostic table.

  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 camshaft position signal circuit disconnected and set DTC P0340. If the counter still increments, this indicates that the PCM is malfunctioning.
  3. 5:  A faulty electrical connection in the camshaft position signal circuit can cause the CMP Resync Counter to increment. Anytime a faulty electrical connection is present, the CMP Reference Activity counter will stop incrementing.
