VACUUM REGULATING VALVE (w/ EGR System without EGR Cooler) INSPECTION

Note

Do not remove the electric vacuum regulating valve from the bracket.


  1. INSPECT ELECTRIC VACUUM REGULATING VALVE ASSEMBLY (for EGR)


    1. Inspect the electric vacuum regulating valve.


      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) 11 to 13 Ω

        1 - Body ground

        2 - Body ground

        		 20°C (68°F) 10 kΩ or higher

        If the result is not as specified, replace the electric EGR control valve assembly.

      *2 Port F
      *3 Filter
      *a Air
      *b Vacuum

      w/ Intercooler:

      Check the operation of the electric vacuum regulating 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.
