Component Test

WARNING: This page is about a different car, the 2009 Saturn Vue. 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 looseness and correct installation. Remove the CKP sensor from the engine and inspect the sensor and the O-ring for damage.
    • If the sensor is loose, incorrectly installed, or damaged, repair or replace the CKP sensor.
  2. Connect the CKP sensor connector to the CKP sensor. Turn ON the ignition, with the engine OFF.
  3. Observe the CKP Active Counter parameter on the scan tool. Pass a steel object by the tip of the sensor repeatedly. The CKP Active Counter parameter should increment.
    • If the parameter does not increment, replace the CKP sensor.
