AIR FUEL RATIO SENSOR INSPECTION

PROCEDURE


  1. INSPECT AIR FUEL RATIO SENSOR (for Bank 1)


    1. A01W0ULE53

      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

      *a

      Component without harness connected

      (Air Fuel Ratio Sensor)

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

  2. INSPECT AIR FUEL RATIO SENSOR (for Bank 2)


    1. A01W0ULE54

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (HA2A) - 2 (+B) 20°C (68°F) 1.6 to 3.2 Ω
      1 (HA2A) - 4 (A2A-) - 10 kΩ or higher
      Text in Illustration
      *a

      Component without harness connected

      (Air Fuel Ratio Sensor)

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