SFI SYSTEM, Diagnostic DTC:P0016, P0017

DTC Code DTC Name
P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
P0017 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B)

DESCRIPTION

The ECM optimizes the valve timing by using the VVT (Variable Valve Timing) system to control the intake and exhaust camshafts. The VVT system includes the ECM, the camshaft timing oil control valve assembly and the VVT controller (camshaft timing gear assembly). The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly.

This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller can advance or retard the intake and exhaust camshafts.

INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the intelligent tester. 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 ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016 AND P0017)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the tester on.

    4. Enter the following menus: Powertrain / Engine / DTC.

    5. Read the DTCs.

      Result
      Result Proceed to
      DTC P0016 or P0017 is output A
      DTC P0016 or P0017 and other DTCs are output B

      Tech Tips

      If any DTCs other than P0016 or P0017 are output, troubleshoot those DTCs first.

      1. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Linear (Bank 1).

      2. Check the engine speed while operating the camshaft timing oil control valve assembly (for intake camshaft) using the tester.

        Result
        Tester Operation Specified Condition
        0% Normal engine speed
        100% Engine idles roughly or stalls
    6. Check the camshaft timing oil control valve assembly (for exhaust camshaft).


      1. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank 1).

      2. Check the engine speed while operating the camshaft timing oil control valve assembly (for exhaust camshaft) using the tester.

        Result
        Tester Operation Specified Condition
        0% Normal engine speed
        100% Engine idles roughly or stalls

        Tech Tips

        If the result is not acceptable, cool the engine and perform the Active Test again.

    OK
  3. CHECK WHETHER DTC OUTPUT RECURS (DTC P0016 OR P0017)


    1. Connect the intelligent tester to the DLC 3.

    2. Turn the engine switch on (IG).

    3. Turn the tester on.

    4. Clear the DTCs Click here.

    5. Start the engine and warm it up.

    6. Idle the engine for 5 minutes or more.

    7. Enter the following menus: Powertrain / Engine / DTC.

    8. Read the pending DTCs.

      Tech Tips


      • If a pending DTC is output, the system is malfunctioning.

      • If a pending DTC is not output, perform the following procedure.

    9. Drive the vehicle for 2 to 3 minutes.

      CAUTION:

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    10. Idle the engine for 5 minutes or more.

    11. Enter the following menus: Powertrain / Engine / DTC.

    12. Read the pending DTCs.

      Result
      Result Proceed to
      DTC is not output A
      DTC P0016 or P0017 is output B

      Tech Tips

      DTC P0016 or P0017 may be stored when foreign objects in the engine oil are caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. These foreign objects may then be captured by the oil filter.
