Circuit/System Verification

  1. With the ignition OFF, inspect the engine wiring harnesses carrying the CKP sensor circuits for the following conditions:
    • Close routing of secondary ignition wires
    • 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. Monitor the CMP RPM and the CMP signal Present parameters. The parameters should indicate RPM and display YES continuously with the engine running or cranking.
  3. 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.
