Oxygen Sensor: Testing and Inspection

HEATED OXYGEN SENSOR INSPECTION (Bank 1 Sensor 2)
1. REMOVE SCUFF PLATE, COWL SIDE TRIM, RH FRONT SEAT AND FLOOR CARPET
2. DISCONNECT HEATED OXYGEN SENSOR CONNECTOR
3. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR





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

Resistance: At 20°C (68°F): 11 - 16 Ohms

- If the resistance is not as specified, replace the heated oxygen sensor.
4. RECONNECT HEATED OXYGEN SENSOR CONNECTOR
5. REINSTALL FLOOR CARPET, RH FRONT SEAT, COWL SIDE TRIM AND SCUFF PLATE
