*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 (HA1B) - 2 (+B)	20°C (68°F)	2 to 6 Ω
1 (HA1B) - 4 (A1B-)	Always	10 kΩ or higher

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