  1. REMOVE AIR FUEL RATIO SENSOR 
    1. Check the resistance.
      1. Using an ohmmeter, measure the resistance between the terminals.

        Standard resistance 

        AIR FUEL RATIO SENSOR

        Tester Connection Specified Condition
        1 (HT) - 2 (+B) 1.8 to 3.4 Ω at 20°C (68°F)
        1 (HT) - 4 (E) 10 kΩ or higher

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