Oxygen Sensor: Testing and Inspection

INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR (Bank 1 Sensor 2)

a. Remove the driver's seat.
b. Disconnect the oxygen sensor connector.





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





Resistance:

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. Reinstall the driver's seat.
