AIR SWITCHING VALVE (w/ Secondary Air Injection System) INSPECTION


  1. INSPECT AIR SWITCHING VALVE ASSEMBLY


    1. A01ERFY

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 5 20°C (68°F)* 4.5 to 5.5 Ω
      1 - Body ground Always 1 MΩ or higher
      5 - Body ground

      Tech Tips

      *: Make sure that the air switching valve is at ambient temperature before measuring the resistance.

      Note

      When measuring the resistance, do not touch terminals 2, 3 and 4.

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

    2. A01ER83E01

      Check the operation of the air switching valve.


      1. Check that air does not flow from port A to port B.

        Note

        Make sure the applied pressure is 30 kPa (0.3 kgf/cm2, 4.4 psi) or less

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

      2. A01EO7QE01

        Apply battery voltage to the connector, and check the air switching valve operation.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → Terminal 1

        Battery negative (-) → Terminal 5

        		 Air flows from port A to port B

        Note

        When applying voltage, do not touch terminals 2, 3 and 4.

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