EGR BYPASS VALVE SWITCHING VALVE INSPECTION

PROCEDURE

  1. INSPECT EGR BYPASS VALVE SWITCHING VALVE (NO. 1 VACUUM SWITCHING VALVE ASSEMBLY)

    1. A201836C01

      *a

      Component without harness connected

      (EGR Bypass Valve Switching Valve (No. 1 Vacuum Switching Valve Assembly))

      Inspect the EGR bypass valve switching valve (No. 1 vacuum switching valve assembly) resistance.

      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)

        28.3 to 31.1 Ω

        If the result is not as specified, replace the EGR bypass valve switching valve (No. 1 vacuum switching valve assembly).

    2. A297483C01

      *a

      Port A

      *b

      Port B

      *c

      Air

      Apply battery voltage between the terminals of the EGR bypass valve switching valve (No. 1 vacuum switching valve assembly) and check that the following occurs when blowing air to the port (A).

      OK

      Measurement Condition

      Specified Condition

      Battery voltage applied between terminals 1 and 2

      Air flows from port (B)

      Battery voltage not applied between terminals 1 and 2

      Air does not flow

      If the result is not as specified, replace the EGR bypass valve switching valve (No. 1 vacuum switching valve assembly).
