  1. Disconnect the vacuum hose from the actuator.

  1. Check the operation of the swirl control valve.

    1. Check that the valve is fully opened under normal conditions.

    2. Connect a vacuum pump to the control valve. Check that the valve is fully closed when a negative pressure of 35 kPa (270 mmHg, 10 in.Hg) is applied.

    3. Wait for 1 minute and check that the vacuum pump needle does not move.
      If the result is not as specified, replace the intake manifold.

  1. Measure the resistance of the VSV.

    Standard resistance:
    Tester Connection
    		Specified Condition
    1 - 2
    		33 to 39 Ω at 20°C (68°F)
    1 - Body ground
    2 - Body ground
    		1 MΩ or higher
    If the result is not as specified, replace the VSV assembly.

  1. Check the operation of the VSV.

    1. Check that air flows from port E to the filter.
      If the result is not as specified, replace the VSV assembly.

    2. Apply battery voltage across the terminals.

    3. Check that air flows from port E to port F.
      If the result is not as specified, replace the VSV assembly.
