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 camshaft position 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 camshaft position sensor.
  2. Connect the camshaft position sensor connector to the camshaft position sensor. Turn ON the ignition, with the engine OFF.
  3. Ignition ON, and engine OFF. Observe the Camshaft Position Active Counter parameter on the scan tool. Pass a steel object by the tip of the sensor repeatedly. The Camshaft Position Active Counter parameter should increment.
    • If the parameter does not increment, replace the camshaft position sensor.
