VACUUM SWITCHING VALVE(for Engine Mounting) INSPECTION

PROCEDURE


  1. INSPECT VACUUM SWITCHING VALVE SUB-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) 37 to 44 Ω

      1 - Body ground

      2 - Body ground

      		 20°C (68°F) 1 MΩ or higher

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

      *a Port E
      *b Port F
      *c Air
      *d Filter

      Check operation of the vacuum switching valve.


      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.

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

        *c 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 sub-assembly.
