Circuit/System Verification

    IMPORTANT: The supply of clean pressurized engine oil to the CMP actuator is essential to CMP actuator performance.
  1. Allow the engine to reach operating temperature.
  2. Set the parking brake and place the vehicle in park for automatic, or neutral for manual.
  3. Observe the CMP variance parameter. The CMP Variance will rise for 1-2 seconds until the CMP Angle parameter matches the Desired CMP parameter. The CMP Variance should again return to 0 degrees.
    4. IMPORTANT: The engine will run rough and may require throttle input to keep running.
  4. Command the CMP actuator to 20 degrees. The Desired CMP parameter should match the CMP Angle parameter.
  5. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
