INSPECTION PROCEDURE

Abnormal bank

(Valve timing is out of specified range)

Retarded timing over

(Valve timing is out of specified range)

Bank 1 P0014 P0015
Bank 2 P0024 P0025

Tech Tips


  • If DTC P0014 or P0015 is displayed, check the bank 1 VVT system circuit.

  • 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.

  • If DTC P0024 or P0025 is displayed, check the bank 2 VVT system circuit.

  • 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

PROCEDURE


  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0014, P0015, P0024 OR P0025)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch on (IG) and turn the tester on.

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

    4. Read the DTCs.

      P0014, P0015, P0024 or P0025 and other DTCs B

      Tech Tips

      If any DTCs other than P0014, P0015, P0024 or P0025 are output, troubleshoot those DTCs first.

  2. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (OPERATE OIL CONTROL VALVE FOR EXHAUST CAMSHAFT)


    1. Connect the intelligent tester to the DLC3.

    2. Start the engine and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Exhaust Linear (Bank 1) or Control the VVT Exhaust Linear (Bank 2).

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

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

    NG
    OK
  3. CHECK WHETHER DTC OUTPUT RECURS (DTC P0014, P0015, P0024 OR P0025)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch on (IG).

    3. Turn the tester on.

    4. Clear the DTCs Click here.

    5. Start the engine and warm it up.

    6. Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more.

      CAUTION:

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

    7. Idle the engine for 3 minutes or more.

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

    9. 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.

    10. Repeat the pattern of accelerating the vehicle from rest to approximately 60 km/h (37 mph) and then decelerating the vehicle 10 to 15 times.

      CAUTION:

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

      Tech Tips

      Depress the accelerator pedal by a large amount.

    11. Idle the engine for 3 minutes or more.

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

    13. Read the pending DTCs.

      Tech Tips

      DTC P0014, P0015, P0024 or P0025 may be stored when foreign objects in 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.

      *1 Timing Mark

      Remove the cylinder head covers RH and LH.

    2. Turn the crankshaft to align the matchmarks of the crankshaft.

    3. Align the notch of the crankshaft pulley to the "0" position.

    4. Check if the matchmarks of the camshaft pulley and camshaft bearing cap align.

    5. Turn the crankshaft clockwise by 360° if the matchmarks do not align. Check if they align once again.

      OK
      The matchmarks of the camshaft pulley and the camshaft bearing cap align when the notch of the crankshaft pulley is in the "0" position.

    NG
