VACUUM REGULATING VALVE INSPECTION

PROCEDURE


  1. INSPECT VACUUM REGULATING VALVE ASSEMBLY


    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) 11.1 to 12.5 Ω

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

    2. Inspect vacuum regulating valve operation.


      1. A00YVU4C02
        A00YXOY Air

        Check that air flows from port E to G.

      2. A00YUJEC02
        *1 Filter
        A00YXOY Air

        Apply battery voltage across terminals 1 and 2 as shown in the illustration.

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

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