On-Vehicle Inspection [12/2015 - 08/2016]: Procedure

WARNING: This page is about a different car, the 2016 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY 
    1. Connect the Techstream to the DLC3.
    2. Start the engine.
    3. Turn the Techstream 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. Check the engine speed when the oil control valve is operated using the Techstream with the engine coolant temperature at 50°C (122°F) or less.

        HINT: 

        • 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.

        OK

        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 / Active Test / Control the VVT System (Bank 2).
      4. Check the engine speed when the oil control valve is operated using the Techstream with the engine coolant temperature at 50°C (122°F) or less.

        HINT: 

        • 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.

        OK

        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.

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

        HINT: 

        • 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.

        OK

        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 / Active Test / Control the VVT Exhaust Linear (Bank 2).
      4. Check the engine speed when the oil control valve is operated using the Techstream with the engine coolant temperature at 50°C (122°F) or less.

        HINT: 

        • 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.

        OK

        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.
