Diagnostic Aids

Check for poor connections at VCM. Inspect KS module connector for backed-out terminals, broken locks, and improperly formed or damaged terminals. Check for damaged or improperly installed KS module. Check for bent pins, deformed terminals, or if KS module is fully seated. Ensure knock sensor is tightened to 14 ft. lbs. (19 N.m). Checking FAILURE RECORDS vehicle mileage data since diagnostic test last failed can be useful in determining how often condition causing DTC to set occurs. This may assist in diagnosis.
