AIR FUEL RATIO SENSOR INSPECTION


  1. INSPECT AIR FUEL RATIO SENSOR


    1. Inspect the A/F heater.


      1. A01BHJ1E03

        Measure the resistance between terminals 1 (HA1A) and 2 (+B) of the sensor.

        Standard resistance
        1.8 to 3.4 Ω at 20°C (68°F)

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

      2. Measure the resistance between terminals 1 (HA1A) and 4 (A1A-) of the sensor.

        Standard resistance
        10 kΩ or higher

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