Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. CHECK FOR AN ACTIVE DTC 
    1. Turn the ignition on.
    2. With the scan tool, read DTCs and record on the repair order.
    3. Record the related Freeze Frame data.
    4. With the scan tool, erase DTCs.
    5. Start the engine and allow it to idle. It maybe necessary to tests drive the vehicle and allow cam phasing to occur in order to reset the fault.
      WARNING:

      When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.

    6. With the scan tool, read DTCs.

      Is the DTC active or pending?

      Yes 

      • Go To  2

      No 

      • Check for any Service Bulletins that may apply and verify the PCM is at the latest calibration available. If OK, remove the Camshaft Position Sensor and inspect for any physical damage to the sensor and the cylinder head, repair as necessary. If no problems were found with CMP Sensor and no updates are available for the PCM and the DTC is intermittent it is possible the CMP Sensor gap to the Camshaft Target Wheel is too large or the CMP Signal circuit is picking up interference from another source. Repair as necessary.
      • Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
  2. CHECK THE ENGINE TIMING ALIGNMENT 
    1. Check the Engine valve timing.

      Perform the following checks and repair as necessary

      Yes 

      • Check for proper alignment of the timing chain and sprocket in accordance with the service information. Also check the Timing Chain Tensioner and Guides for faulty or broken components. Perform the appropriate repair in accordance with the service information. The "Clear Misfire TLC" Procedure  must be performed every time there has been a repair/replacement made to a CMP Sensor and/or CKP Sensor, flywheel, valvetrain, timing chain or gears. Failure to do so can cause a misfire fault to set. With the scan tool, perform the "Cam/Crank Relearn" Procedure.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
