INSPECTION PROCEDURE

Tech Tips

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 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 DTCS OUTPUT (IN ADDITION TO DTC P0014 OR P0015)


    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 the DTCs.

      Result
      Result Proceed to
      DTC P0014 or P0015 is output A
      DTC P0014 or P0015 and other DTCs are output B

      Tech Tips

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

  2. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY)


    1. Connect the intelligent tester to the DLC3.

    2. Start the engine.

    3. Turn the tester on.

    4. Turn the A/C switch on.

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

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

      OK
      Tester Operation Specified Condition
      0% (OFF) Normal engine speed
      127% (ON)

      Engine idles roughly or stalls

      (soon after camshaft timing oil control valve assembly switched from OFF to ON)

      Tech Tips

      If the result is not acceptable, cool the engine and perform the Active Test again.


      1. Start the engine when the engine coolant temperature is 30°C (86°F) or less.

      2. Turn the tester on.

      3. Turn the A/C switch on.

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

      5. Check the engine speed while operating the camshaft timing oil control valve assembly (for exhaust camshaft) using the tester when the engine coolant temperature is 50°C (122°F) or less.

        OK
        Tester Operation Specified Condition
        0% (OFF) Normal engine speed
        127% (ON)

        Engine idles roughly or stalls

        (soon after camshaft timing oil control valve assembly switched from OFF to ON)

  3. CHECK WHETHER DTC OUTPUT RECURS (DTC P0014 OR P0015)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the tester on.

    4. Clear the DTCs Click here.

    5. Start the engine and warm it up.

    6. Switch the ECM from normal mode to check mode using the tester Click here.

    7. Allow the engine to idle for 3 minutes or more.

    8. Drive the vehicle for more than 10 minutes.

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

    10. Read the DTCs.

      Result
      Result Proceed to
      DTC is not output A
      DTC P0014 or P0015 is output B

      Tech Tips

      DTC P0014 or P0015 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. These foreign objects may then be captured by the oil filter.
