CAMSHAFT OIL CONTROL VALVE ON-VEHICLE INSPECTION


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    1. Connect the intelligent tester to the DLC3.

    2. Start the engine.

    3. Turn the intelligent tester on.

    4. Inspect the oil control valve (for intake camshaft).


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

      2. Operate the oil control valve using the intelligent tester, and then check the engine speed.

        Standard Condition
        Control Range Specified Condition
        OCV is OFF Normal engine speed
        OCV is ON Soon after OCV switched from OFF to ON, engine idles roughly or stalls

        If the result is not as specified, check the oil control valve, wire harness and ECM.

      3. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT System (Bank 2).

      4. Operate the oil control valve using the intelligent tester, and then check the engine speed.

        Standard Condition
        Control Range Specified Condition
        OCV is OFF Normal engine speed
        OCV is ON Soon after OCV switched from OFF to ON, engine idles roughly or stalls

        If the result is not as specified, check the oil control valve, wire harness and ECM.

    5. Inspect the oil control valve (for exhaust camshaft).


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

      2. Operate the oil control valve using the intelligent tester, and then check the engine speed.

        Standard Condition
        Control Range Specified Condition
        -100% Normal engine speed
        100% Soon after OCV switched from OFF (- 100%) to ON (+100%), engine idles roughly or stalls.

        If the result is not as specified, check the oil control valve, wire harness and ECM.

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

      4. Operate the oil control valve using the intelligent tester, and then check the engine speed.

        Standard Condition
        Control Range Specified Condition
        -100% Normal engine speed
        100% Soon after OCV switched from OFF (- 100%) to ON (+100%), engine idles roughly or stalls.

        If the result is not as specified, check the oil control valve, wire harness and ECM.
