Heated Oxygen Sensor (Bank 1,2 Sensor 1)

OXYGEN SENSORS INSPECTION

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





(b) Using an ohmmeter, measure the resistance between the 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 (440 kgf.cm, 31 ft.lbf)
