Air-Fuel Ratio (A/F) Sensor

INSPECTION

1. INSPECT HEATER RESISTANCE OF A/F SENSOR
a. Disconnect the sensor connector.




b. Using an ohmmeter, measure the resistance between terminals +B and HT




If the resistance is not as specified, replace the sensor

Torque: 20 N.m (200 kgf.cm, 14 ft.lbf)

c. Connect the sensor connector.

2. INSPECT OPERATION OF A/F SENSOR
