VACUUM SWITCHING VALVE INSPECTION


  1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY


    1. A017DIYE02

      Inspect VSV operation.


      1. Using an ohmmeter, measure the resistance according to the value(s) in the table below.

        Standard resistance
        Tester Connection Condition Specified Condition
        1 - 2 20°C (68°F) 37 to 44 Ω

        If the result is not as specified, replace the VSV.

    2. Inspect the VSV for a short to ground.


      1. A017FOIE03

        Using an ohmmeter, measure the resistance according to the value(s) in the table below.

        Standard resistance
        Tester Connection Condition Specified Condition
        1 - Body ground 20°C (68°F) 10 kΩ or higher
        2 - Body ground 20°C (68°F) 10 kΩ or higher

        If the result is not as specified, replace the VSV.

    3. A017EB1E01

      Inspect VSV operation.


      1. Check that air flows from port E to the filter.

      2. Apply battery voltage across the terminals.

      3. Check that air flows from port E to port F.

        If operation is not as specified, replace the VSV.
