CAMSHAFT OIL CONTROL VALVE ON-VEHICLE INSPECTION


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Turn the GTS on.

    4. Turn the A/C switch on.

    5. Inspect the camshaft timing oil control valve assembly (for intake side).


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

      2. Check the engine speed while operating the camshaft timing oil control valve assembly (for intake side) using the tester.

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

        Tech Tips

        If the result is not acceptable, allow the engine to cool (engine coolant temperature 50°C (122°F) or less) and perform the Active Test again.

    6. Inspect the camshaft timing oil control valve assembly (for exhaust side).


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

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

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