MONITOR DESCRIPTION

The crankshaft position sensor is used to identify engine position and speed via pole wheel mounted on the front end of the crankshaft. The camshaft position sensor is used to determine camshaft position from a three vane reluctor on the rear end of the inlet and exhaust camshaft. Fault codes P0016, P0017, indicate a mechanical timing error such as incorrectly set, or 'jumped' cam timing.

CAUTION / NOTICE / HINT

Tech Tips


  • The monitor for this DTC detects when the timing chain is shifted by one tooth or more.

  • Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Trouble Codes.

    5. Read the DTCs.

      Result
      Result Proceed to
      DTC P0016 is output A
      DTC P0016 and other DTCs are output B

      Tech Tips

      If any DTCs other than P0016 are output, troubleshoot those DTCs first.

  2. PERFORM ACTIVE TEST USING GTS (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY)

    Tech Tips

    If the VVT system can be operated through the Active Test, it can be assumed that the VVT system is operating normally.


    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Turn the A/C switch on.

    4. Turn the GTS on.

    5. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Linear (Bank 1) or Control the VVT Exhaust Linear (Bank 1) / Gas Valve Control / VVT Change Angle #1 or VVT Ex Chg Angle #1.

    6. Perform the Active Test. Check that the displacement angle varies.

      OK
      Displacement angle varies.

  7. CHECK WHETHER DTC OUTPUT RECURS (DTC P0016)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Clear the DTCs.

    5. Turn the engine switch off and wait for at least 30 seconds.

    6. Turn the engine switch on (IG).

    7. Turn the GTS on.

    8. Start the engine and warm it up.

    9. Enter the following menus: Powertrain / Engine / Trouble Codes.

    10. Read the DTCs.
