VACUUM SWITCHING VALVE(for ACIS) ON-VEHICLE INSPECTION

PROCEDURE

  1. INSPECT VACUUM SWITCHING VALVE (for ACIS)

    1. A205681E05

      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. Check the VSV operation.

      1. A205682E05

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

      2. A205683E05

        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.
