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


  1. INSPECT AIR SWITCHING 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) 4.5 to 5.5 Ω
      1 - Body ground Always 1 MΩ or higher
      2 - Body ground

      Tech Tips

      When measuring the resistance, make sure that the surface temperature of the air switching valve is 20°C (68°F).

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