CAMSHAFT OIL CONTROL VALVE ON-VEHICLE INSPECTION


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (w/ Dual VVT-i)


    1. for Intake Side:


      1. Connect the GTS to the DLC3.

      2. Start the engine.

      3. Turn the GTS on.

      4. Warm up the engine.

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

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

        Specified Condition
        GTS Operation Specified Condition
        0% Normal engine speed
        100% Engine idles roughly or stalls

        If the result is not as specified, check the camshaft timing oil switching valve assembly, wire harness and ECM.

    2. for Exhaust Side:


      1. Connect the GTS to the DLC3.

      2. Start the engine.

      3. Turn the GTS on.

      4. Warm up the engine.

      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 using the GTS.

        Specified Condition
        GTS Operation Specified Condition
        0% Normal engine speed
        100% Engine idles roughly or stalls

        If the result is not as specified, check the camshaft timing oil switching valve assembly, wire harness and ECM.

  2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (w/o Dual VVT-i)


    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Turn the GTS on.

    4. Warm up the engine.

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

    6. Operate the camshaft timing oil control valve using the intelligent tester, and check the engine using the intelligent tester, and check the engine

      Specified Condition
      Tester Operation Specified Condition
      Camshaft timing oil control valve OFF Normal engine speed
      Camshaft timing oil control valve ON Engine idles roughly or stalls soon after OCV switched from OFF to ON

      If the result is not as specified, check the camshaft timing oil switching valve assembly, wire harness and ECM.
