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 and turn the intelligent tester on.

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


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

      2. Check the engine speed when the oil control valve is operated using the intelligent tester with the engine coolant temperature at 50°C (122°F) or less.

        Tech Tips


        • When performing the Active Test, the air conditioning should be on.

        • Engine coolant temperature when the engine is started should be 30°C (86°F) or less.

        Standard Condition
        Tester Operation Specified Condition
        OFF Normal engine speed
        ON Soon after OCV switched from OFF to ON, engine idles roughly or stalls

    4. 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. Check the engine speed when the oil control valve is operated using the intelligent tester with the engine coolant temperature at 50°C (122°F) or less.
