AIR FUEL RATIO SENSOR INSPECTION

PROCEDURE


  1. INSPECT AIR FUEL RATIO SENSOR

    A01L8LFC04
    *A for Bank 1
    *B for Bank 2
    *a

    Component without harness connected

    (Air Fuel Ratio Sensor)

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

      Standard Resistance (for Bank 1)
      Tester Connection Condition Specified Condition
      1 (HA1A) - 2 (+B) 20°C (68°F) 1.8 to 3.4 Ω
      1 (HA1A) - 4 (A1A-) Always 10 kΩ or higher
      Standard Resistance (for Bank 2)
      Tester Connection Condition Specified Condition
      1 (HA2A) - 2 (+B) 20°C (68°F) 1.8 to 3.4 Ω
      1 (HA2A) - 4 (A2A-) Always 10 kΩ or higher

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