1. INSPECT AIR FUEL RATIO SENSOR


  1. Check the resistance.



      A265208E02
    1. Measure the resistance according to the value(s) in the table below.

      Text in Illustration 
      *A
      for Bank 1
      *B
      for Bank 2
      *a
      Component without harness connected
      (Air Fuel Ratio Sensor)

      Standard Resistance:
      Tester Connection
      Condition
      Specified Condition
      1 (HA1A) - 2 (+B)
      (for Bank 1)
      20°C(68°F)
      1.6 to 3.2 Ω
      1 (HA2A) - 2 (+B)
      (for Bank 2)
      1 (HA1A) - 4 (A1A-)
      (for Bank 1)
      Always
      10 kΩ or higher
      1 (HA2A) - 4 (A2A-)
      (for Bank 2)
      If the result is not as specified, replace the air fuel ratio sensor.
