DESCRIPTION

Refer to DTC P0010 Click here.

DTC No. DTC Detection Condition Trouble Area
P0011 Difference between the target camshaft angle and the actual camshaft angle is more than 10° after foreign object removal activation operated (2 trip detection logic)

  • Valve timing

  • Camshaft timing oil control valve assembly

  • Camshaft timing sprocket assembly

  • Oil control valve filter

  • Camshaft timing oil control valve assembly circuit

  • ECM
P0011

Relative angle of the camshaft and crankshaft deviates by 10° CA (crankshaft angle) from the standard angle at the advanced VVT side

(3 trip detection logic)

  • Valve timing (jumped teeth of timing chain, chain stretched)

  • Camshaft timing oil control valve assembly

  • Camshaft timing sprocket assembly

  • Oil control valve filter

  • Camshaft timing oil control valve assembly circuit

  • ECM
P0012

Relative angle of the camshaft and crankshaft deviates by 15° CA from the standard angle at the retarded VVT side

(3 trip detection logic)

Tech Tips


  • DTC P0011 (system performance) is detected when the vehicle is driven in the city for approximately 20 minutes after warm- up (repetitive acceleration for 3 seconds and deceleration for 5 seconds).

  • DTC P0011 (timing over advanced) and P0012 are detected when the engine idles for approximately 15 seconds after warm-up. If not detected, then rev the engine and then idle it for 15 seconds again.

Tech Tips


  • DTC P0011 or P0012 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. Those foreign objects may then be captured by the oil filter.

  • Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. 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 DTC OUTPUT (IN ADDITION TO DTC P0011 OR P0012)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the tester on.

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

    5. Read DTCs.

      Result
      Result Proceed to
      DTC P0011 or P0012 is output A
      DTC P0011 or P0012, and other are output B

      Tech Tips

      If any DTCs other than P0011 or P0012 are output, troubleshoot those DTCs first.

  2. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (CONTROL THE VVT SYSTEM (BANK 1))


    1. Connect the intelligent tester to the DLC3.

    2. Start the engine.

    3. Turn the tester on.

    4. Warm up the engine.

    5. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT system (Bank 1).

    6. Check the engine speed while operating the camshaft timing oil control valve assembly using the tester.

      Result
      Specified Condition Proceed to
      Engine changes from steady idling to rough idling or engine stalling A
      No change in engine speed B

  3. CHECK VALVE TIMING (CHECK FOR LOOSE TIMING CHAIN JUMPED TEETH)


    1. Check for looseness or a jumped tooth in the timing chain Click here.

      OK
      The match marks of the crankshaft pulley and camshaft pulley align.

    ADJUST VALVE TIMING Click here

    OK

  4. CHECK WHETHER DTC OUTPUT RECURS (DTC P0011 OR P0012)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the tester on.

    4. Clear DTCs Click here.

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

    6. Turn the ignition switch to ON.

    7. Turn the tester on.

    8. Start the engine and warm it up.

    9. Drive the vehicle for 20 minutes or more.

    10. Enter the following menus: Powertrain / Engine and ECT / DTC.

    11. Read the pending DTCs.

      Result
      Result Proceed to
      DTC P0011 or P0012 is output A
      DTC is not output B

      Tech Tips

      DTC P0011 or P0012 may be set 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. Foreign objects are filtered out by the oil filter.
