Oxygen Sensor: Testing and Inspection

INSPECTION
(Bank 1 Sensor 1, Bank 1 Sensor 2)
INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSORS
- Disconnect the oxygen sensor connector.





- 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 sensor.

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

- Reconnect the oxygen sensor connector.
