Heated Oxygen Sensor

1. 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 Ohm 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)

c. Reconnect the oxygen sensor connector.




2. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR (Bank 1 Sensor 2)
a. Remove the passenger's seat.
b. Take out the floor carpet.
c. Disconnect the oxygen sensor connector.
d. Using an ohmmeter, measure the resistance between the terminals +B and HT.

Resistance: 11 - 16 Ohm 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)

e. Reconnect the oxygen sensor connector.
f. Reinstall the floor carpet.
g. Reinstall the passenger's seat.
