Oxygen Sensor: Testing and Inspection

HEATED OXYGEN SENSOR INSPECTION
1. 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 ohm

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

Torque: 44N m (45O kgf.cm, 33 ft.lbf)
