a. Remove the driver'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:
- At 20 °C (68 °F) 11 - 16 Ohms
- At 800 °C (1,472 °F) 23 - 32 Ohms
- If the resistance is not as specified, replace the sensor.
e. Reconnect the oxygen sensor connector.
- Torque: 44 Nm (450 kg.cm, 32 ft.b)
f. Reinstall the floor carpet.
g. Reinstall the driver's seat.
