      Text in Illustration 
      *1
      		Component without harness connected
      (Air Fuel Ratio Sensor)

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      1 (HA1A) - 2 (+B)
      		20 °C (68 °F)
      		2.64 to 2.9 Ω
      1 (HA1A) - 4 (A1A-)
      		Always
      		10 kΩ or higher

      If the result is not as specified, replace the air fuel ratio sensor.
