Air-Fuel Ratio (A/F) Sensor

INSPECTION

INSPECT HEATER RESISTANCE OF A/F SENSORS (Bank 1,2 Sensor 1)

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: 44 N.m (450 kgf.cm, 32 ft.lbf)

c. Reconnect the sensor connector.
