Diagnostic Procedures

WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off for 10 seconds. Using scan tool, monitor CMP RESYNC COUNTER while the following: Start engine and slowly accelerate to wide open throttle 5 times. Let engine idle for 30 seconds. If any counts are present, go to next step. If no counts are present, problem is intermittent. See DIAGNOSTIC AIDS  .
  2. If engine cuts out when count(s) were showing up on scan tool, repair intermittent open in CKP sensor circuit. Check the following:
    • CKP sensor mounting bolt for tightness.
    • Connections on Yellow wire and Purple wire between ECM and CKP sensor.

    If engine does not cut out when count(s) were showing up on scan tool, check for Electromagnetic interference (EMI) on crankshaft sensor circuit. Check harness routing to make sure it is away from battery cables and attached to appropriate clips and retainers. Check generator/starter for electrical noise.
