AIR FUEL RATIO SENSOR INSPECTION

PROCEDURE


  1. INSPECT AIR FUEL RATIO SENSOR


    1. A002CLDC16
      *A for Bank 1
      *B for Bank 2
      *a

      Component without harness connected

      (Air Fuel Ratio Sensor)

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

      Standard Resistance
      Tester Connection Condition Specified Condition

      1 (HA1A) - 2 (+B)

      1 (HA2A) - 2 (+B)

      		 20°C (68°F) 1.6 to 3.2 Ω

      1 (HA1A) - 4 (A1A-)

      1 (HA2A) - 4 (A2A-)

      		 Always 10 kΩ or higher

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