CAMSHAFT OIL CONTROL VALVE ON-VEHICLE INSPECTION

PROCEDURE

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

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

        Powertrain > Engine and ECT > Active Test

        Tester Display

        Control the VVT System (Bank1)

      2. Check the engine speed when the camshaft timing oil control valve assembly is operated using the GTS with the engine coolant temperature 50°C (122°F) or less.

        OK

        Condition

        Specified Condition

        Oil control valve OFF

        Normal engine speed

        Oil control valve ON

        Rough idle or engine stalled

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

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

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

        Powertrain > Engine and ECT > Active Test

        Tester Display

        Control the VVT Exhaust Linear (Bank1)

      2. Check the engine speed when the camshaft timing oil control valve assembly is operated using the GTS with the engine coolant temperature 50°C (122°F) or less.

        OK

        Condition

        Specified Condition

        -128% (Oil control valve OFF)

        Normal engine speed

        127% (Oil control valve ON)

        Rough idle or engine stalled

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