SFI SYSTEM(w/ Canister Pump Module), 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. Detection Item DTC Detection Condition Trouble Area MIL Memory

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.

    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • Unable to perform DTC judgment

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

    Tech Tips


    • 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.

    Tech Tips

    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.

    Tech Tips


    • 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.

    Tech Tips


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

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

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 power switch on (IG).

    3. Turn the GTS on.

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

    5. Read the DTCs.

      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 (CONTROL THE VVT LINEAR)

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

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

      Click here


      Powertrain > Hybrid Control > Utility
      Tester Display
      Inspection Mode

    4. Start the engine.

    5. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Linear (Bank 1) / Ptrl Valve Control / VVT Change Angle #1.


      Powertrain > Engine and ECT > Active Test
      Active Test Display
      Control the VVT Linear (Bank1)

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

      OK
      Displacement angle varies.

      Tech Tips


      • 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.
