Diagnostic Aids

Check for faulty connection at VCM. Check KS and VCM connectors for damage. Ensure KS harness is not routed too close to high-voltage wires, such as spark plug cables, ignition coils or other high-voltage components. Insure KS is installed properly and tightened to specification. Torque specification is 14 ft. lbs. (19 N.m). Review FAIL RECORDS to determine frequency of knock condition.
