SFI SYSTEM(w/o EGR System), Diagnostic DTC:P0016

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

DESCRIPTION

In the VVT (Variable Valve Timing) system, the appropriate intake valve open and close timing is controlled by the ECM. The ECM performs intake valve control by performing the following: 1) controlling the intake camshaft and camshaft timing oil control valve assembly, and operating the camshaft timing gear assembly; and 2) changing the relative positions of the camshaft and crankshaft.

DTC No.

MONITOR DESCRIPTION

To monitor the correlation of the intake camshaft position and crankshaft position, the ECM checks the VVT learned value while the engine is idling. The VVT learned value is calibrated based on the camshaft position and crankshaft position. The intake valve timing is set to the most retarded angle while the engine is idling. If the VVT learned value is out of the specified range in consecutive driving cycles, the ECM illuminates the MIL and stores DTC P0016.

  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the power switch off and wait for at least 30 seconds.

  5. Turn the power switch on (IG) and turn the GTS on [A].

  6. Put the engine in inspection mode (maintenance mode).

  7. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [B].

  8. Idle the engine for 5 minutes or more [C].

  9. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [D].

  10. Read the pending DTCs.

    Tip:

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

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

  11. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

  12. Input the DTC: P0016.

  13. Check the DTC judgment result.

    Description

    NORMAL

    • DTC judgment completed

    • System normal

    ABNORMAL

    • DTC judgment completed

    • System abnormal

    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions

    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
    Tip:

    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform steps [E] through [G].

  14. With the engine running, drive the vehicle at 60 km/h (37 mph) for 2 to 3 minutes [E].

    CAUTION:

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

    Tip:

    If the engine stops, further depress the accelerator pedal to restart the engine.

  15. Idle the engine for 5 minutes or more [F].

  16. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [G].

  17. Read the pending DTCs.

    Tip:

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

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

  18. Check the DTC judgment result.

    Tip:

    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

Tip:

  • 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 power switch on (IG).

    3. Turn the GTS on.

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

    5. Read the DTCs.

  2. PERFORM ACTIVE TEST USING GTS (CONTROL THE VVT LINEAR)

    Tip:

    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. Turn the power switch on (IG) and turn the GTS on.

    3. Put the engine in inspection mode (maintenance mode).

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

      OK

      Displacement angle varies.

      Tip:

      • Test not possible with the shift lever in P during charge control. Move the shift lever to N to perform test.

      • If the DTCs are stored after the Active Test, clear the DTCs.
