INSPECTION PROCEDURE

Tech Tips

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 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)


    1. Connect the intelligent tester to the DLC3.

    2. Start the engine.

    3. Turn the tester on.

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

    5. Check the engine speed when the camshaft timing oil control valve is operated using the intelligent tester when the engine coolant temperature is 50°C (122°F) or less.

      Tech Tips


      • When performing the Active Test, make sure the air conditioning is on.

      • Make sure the engine coolant temperature when the engine is started is 30°C (86°F) or less.

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

    OK

  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 more than 1 minute.

    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 is output when foreign objects in the engine oil are caught in some parts of the system. These codes remain stored for a short time even after the system returns to normal. These foreign objects may then be captured by the oil control valve filter, thus eliminating the source of the problem.

  4. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE


    1. A005SWVE02

      Remove the camshaft timing oil control valve.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 6.9 to 7.9 Ω

      Component without harness connected

      (Camshaft Timing Oil Control Valve)
    3. A005UJVE04

      Connect the positive (+) battery terminal to terminal 1 and the negative (-) battery terminal to terminal 2. Check the valve operation.

      OK
      Valve moves quickly.

    4. Reinstall the camshaft timing oil control valve.

  5. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY


    1. Inspect the camshaft timing gear assembly Click here.


    NG

    REPLACE CAMSHAFT TIMING GEAR ASSEMBLY Click here

    OK

  6. INSPECT OIL CONTROL VALVE FILTER


    1. A005RUV

      Remove the oil control valve filter.

    2. Check that the filter is not clogged.

      OK
      Filter is not clogged.

    3. Reinstall the oil control valve filter.


    NG

    REPLACE OIL CONTROL VALVE FILTER

    OK

  7. ADJUST VALVE TIMING

    Tech Tips

    There are no marks on the cylinder head to align for the purpose of checking valve timing. Valve timing can only be inspected by aligning the colored plates on the timing chain with the marks on the pulleys. It may be necessary to remove and reinstall the chain to align the timing marks Click here.
