NOTICE:

  Do not remove the electric vacuum regulating valve.

1. INSPECT ELECTRIC VACUUM REGULATING VALVE (for EGR)

1. Measure the resistance of the E-VRV.

   Standard resistance:

     Tester Connection | Specified Condition
     1 - 2 | 11 to 13 Ω at 20°C (68°F)
     1 - Body Ground 2 - Body Ground | 10 MΩ or higher

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

1. Check operation of the E-VRV.

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

   2. 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 electric vacuum regulating valve.
