(Air Fuel Ratio Sensor)


w/o Secondary Air Injection System:

i.

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-) Always 10 kΩ or higher


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