Circuit/System Verification
- With the ignition OFF, inspect the engine wiring harnesses carrying the camshaft position sensor circuits for the following conditions:
- Close routing of aftermarket electrical equipment
- Close to solenoids, motors, and relays
- Correct any wire harness routing or component placement conditions, if it is determined to be a possible source of electrical interference
- Ignition ON, engine OFF, observe the Camshaft Position Active Counter parameter. The Camshaft Position Active Counter should be at 0.
- Start and run the engine. The Camshaft Position Active Counter should increment to 255.
