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
      1 - Vacuum regulating valve assembly body ground Always 10 MΩ or higher
      2 - Vacuum regulating valve assembly body ground 10 MΩ or higher

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

    2. Check the operation of the vacuum regulating valve assembly.

        *a Port (E)
        *b Port (F)
        *c Air

        Using a vacuum pump, apply a vacuum of 67 kPa (503 mmHg, 19.8 in. Hg) to the port (F) and check that the vacuum regulating valve operates normally.

      2. Check that air flows from the filter when air is blown into the port (E).

        Tech Tips

        When air is blown into the port (E), the vacuum of the port (F) decreases.

        *a Port (E)
        *b Port (F)
        *c Air

        Apply battery voltage between the terminals, and check that air flows from the port (F) when air is blown into the port (E).
