MONITOR DESCRIPTION

These DTCs are stored when a deviation in the valve timing is detected. If a deviation in the valve timing is detected when the engine is idling (during valve timing learning) after performing learning value reset using the GTS or when the vehicle is being driven, the ECM determines that a malfunction has occurred. If a deviation in the valve timing is detected in consecutive driving cycles, the ECM illuminates the MIL and stores a DTC.

If the valve timing has deviated, the camshaft position sensor malfunction DTC P1340 may be stored.

A DTC is output if the following occurs: 1) the engine is idled, and then the engine switch is turned off; and 2) the engine is started and the engine is idled.

DTC P0016 and/or P0018 may be output if the battery is reconnected and the engine is started while the following are disconnected from the camshaft timing control motor: 1) power source harness or connector; or 2) ECM harness or connector.

If P0016 and/or P0018 is output, check if the harness or connector is disconnected.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

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

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

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

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

  8. Enter the following menus: Powertrain / Engine / Trouble Codes [D].

  9. 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.

  10. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

  11. Input the DTC: P0016 or P0018.

  12. Check the DTC judgment result.

    GTS Display 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].

  13. Drive the vehicle for 2 to 3 minutes [E].

    CAUTION:

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

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

  15. Enter the following menus: Powertrain / Engine / Trouble Codes [G].

  16. 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.

  17. 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 malfunction.

CAUTION / NOTICE / HINT

Tip:

  • The GTS only:

    By using the Control the VVT-iE Linear (Bank 1) or Control the VVT-iE Linear (Bank 2) Active Test, it can be determined if the VVT-iE system is malfunctioning.


    1. Connect the GTS to the DLC3.

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

    3. Start the engine and warm it up.

    4. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT-iE Linear (Bank 1) or Control the VVT-iE Linear (Bank 2).

    5. Monitor VVT Target Angle #1 and VVT Change Angle #1 or VVT Target Angle #2 and VVT Change Angle #2.

    6. Perform the Active Test operation with the engine speed at 1500 rpm.

      Table 1. OK:
      Active Test Movement Order Difference between "VVT Target Angle" and "VVT Change Angle"
      0 deg → 10 deg → 20 deg → 40 deg → 10 deg → 0 deg → 10 deg → END Within 5 DegFR

  • Bank 1 refers to the bank that includes the No. 1 cylinder*.

    *: The No. 1 cylinder is the cylinder which is farthest from the transmission.

  • Bank 2 refers to the bank that does not include the No. 1 cylinder.

  • 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.

    CHECK ANY OTHER DTCS OUTPUT (P0016 OR P0018)


    1. Connect the GTS to the DLC3.

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

    1. Remove the cylinder head covers.

    2. Turn the crankshaft pulley, and align its groove with the timing mark "0" of the timing chain cover.

    3. Check that the timing marks of the camshaft timing gears and camshaft timing exhaust gears are at the positions shown in the illustration.

      OK
      The timing marks on the camshaft timing gears are aligned as shown in the illustration.
      Tip:

      • If the result is not as specified, check for mechanical malfunctions that may have affected the valve timing, such as a jumped tooth or stretching of the timing chain.

      • When checking the valve timing, make sure the camshaft timing gear assemblies are set to the most retarded position and the camshaft timing exhaust gear assemblies are set to the most advanced position. When the VVT system is normal and the engine is stopped, the camshaft timing gear assemblies stop at the center of their operation range and the camshaft timing exhaust gear assemblies stop at the most advanced position.
