VACUUM SWITCHING VALVE(for ACIS) ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT VACUUM SWITCHING VALVE (for ACIS)


    1. 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) 27 to 33 Ω
      1 - Body ground Always 1 MΩ or higher
      2 - Body ground

      If the result is not as specified, replace the vacuum switching valve.

    2. A00YU25C01
      *1 Filter
      A00YXOY Air

      Check the VSV operation.


      1. When vacuum is applied to port E, check that air is sucked into the filter.

      2. A00YR5MC01
        A00YXOY Air

        Apply battery voltage to the terminals as shown in the illustration. When vacuum is applied to port F, check that air is sucked into port E.

        If the result is not as specified, replace the vacuum switching valve.
