Sub Heated Oxygen Sensor Testing

SUB OXYGEN SENSOR INSPECTION

1. Inspect operation of sub heated oxygen sensor.
2. Inspect heater resistance of sub heated oxygen sensor.
- Remove the driver's seat.
- Take out the console box side of the floor carpet.
- Disconnect the oxygen sensor connector.





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

Resistance: At 20°C (68°F) 11 - 18 Ohms

- If the resistance is not as specified, replace the sensor.

Torque: 20 N.m (200 kgf.cm, 14 ft.lbf)

- Reconnect the oxygen sensor connector.
- Reinstall the floor carpet.
- Reinstall the driver's seat.
