Heated Oxygen Sensor (Bank 1, 2 Sesnor 1)

INSPECTION

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





(b) 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)

(c) Reconnect the oxygen sensor connector.
