      (Vacuum Switching Valve)

      Inspect the No. 1 and No. 2 vacuum switching valves.

      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) 33 to 39 Ω

      1 - Body ground

      2 - Body ground

      		 20°C (68°F) 10 kΩ or higher

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

      *3 Vacuum
      *4 Air
      *5 Filter

      Check operation of the No. 1 and No. 2 vacuum switching valves.


      1. When a vacuum of 67 kPa (500 mmHg, 19.7 in.Hg) is applied to port F, check that air flows from port E to the filter.

        *3 Air

        Apply battery voltage across terminals 1 and 2.

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

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