Heated Oxygen Sensor (Bank 1 Sensor 2)

INSPECTION

INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR (Bank 1,2 Sensor 2)
(a) Take out the floor carpet.
(b) Disconnect the oxygen sensor connector.





(c) Using an ohmmeter, measure the resistance between terminals +B and HT.

Resistance: 11 - 16 Ohms at 20° C (68° F)

If the resistance is not as specified, replace the sensor.

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

(d) Reconnect the oxygen sensor connector.
(e) Install the floor carpet.
