INSPECT AIR FUEL RATIO SENSOR

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

• Standard Resistance:

• Tester Connection	Condition	Specified Condition
  1 (HA1A) - 2 (+B) for Bank 1	20°C (68°F)	1.8 to 3.4 Ω
  1 (HA2A) - 2 (+B) for Bank 2	20°C (68°F)	1.8 to 3.4 Ω

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