CAMSHAFT OIL CONTROL VALVE ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    1. Connect the GTS to the DLC3.

    2. Put the engine in inspection mode Click here.

    3. Start the engine.

    4. Turn the GTS on.

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


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

      2. Check the engine speed when the oil control valve is operated using the GTS.

        Tech Tips

        The test is not possible with the shift lever in P during charge control. Move the shift lever to N to perform the test.

        Standard Condition
        Control Range Specified Condition
        OFF Normal engine speed
        ON Rough idle or engine stalls (soon after oil control valve switched from OFF to ON)

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

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

      4. Check the engine speed when the oil control valve is operated using the GTS.

        Tech Tips

        The test is not possible with the shift lever in P during charge control. Move the shift lever to N to perform the test.

        Standard Condition

        Standard Condition
        Control Range Specified Condition
        -100% Normal engine speed
        100% Rough idle or engine stalls (soon after oil control valve switched to 100%)

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

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