SUB-HEATED OXYGEN SENSOR INSPECTION
1. INSPECT OPERATION OF SUB HEATED OXYGEN SENSOR.




2. INSPECT HEATER RESISTANCE OF SUB HEATED OXYGEN SENSOR.
- Remove the scuff plate.
- Remove the instrument panel under cover.
- Take out the front 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): 11.7 - 14.3 Ohms

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

Torque: 44 N.m (450 kgf.cm, 33 ft.lbf)

- Reconnect the oxygen sensor connector.
- Reinstall the floor carpet.
- Reinstall the instrument panel under cover.
- Reinstall the scuff plate.
