VACUUM SWITCHING VALVE(for ACIS) ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)

   
   

   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) 33 to 39 Ω 1 - Body ground Always 1 MΩ or higher 2 - Body ground

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

   2. Check the VSV operation.

      
      
      1. 

         *a	Filter
         *b	Port E
         	Air

         Check that air flows from port E to the filter.

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

      2. 

         *a	Port E
         *b	Port F
         	Air

         Apply battery voltage across the terminals.

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

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