Circuit/System Verification

  1. 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.

  2. Engine idling, observe the scan tool Camshaft Position Active Counter parameters. Both parameters should be incrementing.
  3. Engine idling, observe the DTC information with a scan tool. DTC P0340 should not set.
  4. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
