Oxygen Sensor: Testing and Inspection

COMPONENTS FOR REMOVAL AND INSTALLATION

HEATED OXYGEN SENSOR INSPECTION

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
