Oxygen Sensor: Testing and Inspection

HEATED OXYGEN SENSOR

INSPECT HEATER RESISTANCE OF OXYGEN 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: 44 N.m (450 kgf.cm, 32 ft.lbf)

c. Reconnect the sensor connector.
