      *a

      Component without harness connected

      (Air Fuel Ratio Sensor)

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (HA1A) - 2 (+B) 20°C (68°F) 1.6 to 3.2 Ω
      1 (HA1A) - 4 (A1A-) - 10 kΩ or higher

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