(Heated Oxygen Sensor)


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

Standard Resistance:
Tester Connection Condition Specified Condition
1 (HT1B) - 2 (+B) 20°C (68°F) 11 to 16 Ω
1 (HT1B) - 4 (E2) Always 10 kΩ or higher


If the result is not as specified, replace the heated oxygen sensor.
