Component Testing

WARNING: This page is about a different car, the 2008 Pontiac G5 and 2008 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: You must perform the Circuit/System Testing before proceeding with Component Testing.
  1. Inspect the CKP sensor for correct installation. Remove the CKP sensor from the engine and inspect the sensor O-ring for damage.
  2. Connect the CKP sensor harness connector to the CKP sensor.
  3. Ignition ON, engine OFF, observe the CKP Active Counter while passing a steel object by the tip of the sensor repeatedly. The CKP Active Counter should increment.
    • If the CKP Active Counter does not increment, replace the CKP sensor.
