HEATED OXYGEN SENSOR INSPECTION

PROCEDURE


  1. INSPECT HEATED OXYGEN SENSOR


    1. for Bank 1:


      1. A01R8WHC01
        *a

        Component without harness connected

        (Heated Oxygen Sensor)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        2 (HT1B) - 1 (+B) 20°C (68°F) 5 to 10 Ω
        2 (HT1B) - 3 (E2) Always 10 kΩ or higher

        If the result is not as specified, replace the heated oxygen sensor.

    2. for Bank 2:


      1. A01RDFOC04
        *a

        Component without harness connected

        (Heated Oxygen Sensor)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 (HT2B) - 2 (+B) 20°C (68°F) 5 to 10 Ω
        1 (HT2B) - 4 (E2) Always 10 kΩ or higher

        If the result is not as specified, replace the heated oxygen sensor.
