1. INSPECT VACUUM SWITCHING VALVE (for EGR Cut)

1. Measure the resistance of the VSV.

   Standard resistance:

     Tester Connection | Specified Condition
     1 - 2 | 37 to 44 Ω at 20°C (68°F)
     1 - Body Ground 2 - Body Ground | 1 MΩ or higher

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

1. Check operation of the VSV.

   1. Check that air dose not flow from port E to the filter.
      If the result is not as specified, replace the vacuum switching valve.

   2. Apply battery voltage across terminals 1 and 2.

   3. Check that air flows from port E to the filter.
      If the result is not as specified, replace the vacuum switching valve.
