Component Testing

NOTE:

You must perform the Circuit/System Testing before proceeding with Component Testing.

  1. Inspect the camshaft position sensor for correct installation. Remove the B23 camshaft position sensor from the engine and inspect the sensor O-ring for damage.
    • If the sensor is loose, incorrectly installed, or damaged, replace the B23 camshaft position sensor.
  2. Connect the camshaft position sensor harness connector to the B23 camshaft position sensor.
  3. Ignition ON, observe the Camshaft Position Active counter parameter with a scan tool while passing a flat steel object across the tip of the sensor repeatedly. The Camshaft Position Active counter parameter should increment with each pass of the steel object.
    • If the function does not perform as specified, replace the B23 camshaft position sensor.
