Component Testing

NOTE: You must perform the Circuit/System Testing before proceeding with Component Testing.
  1. Inspect the crankshaft position sensor for correct installation. Remove the crankshaft position sensor from the engine and inspect the sensor O-ring for damage.
    • If the sensor is loose, incorrectly installed, or damaged, replace the crankshaft position sensor.
  2. Connect the crankshaft position sensor harness connector to the crankshaft position sensor.
  3. Ignition ON, engine OFF. Observe the Crankshaft Position Active counter parameter on the scan tool.
  4. Pass a flat steel object across the tip of the sensor repeatedly. The Crankshaft Position Active counter parameter should increment with each pass of the steel object.
    • If the parameter does not increment, replace the crankshaft position sensor.
