Bank 1, 2 Sensor 1

INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSORS
- Disconnect the oxygen sensor connectors.





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

Resistance: At 20°C (68°F): 11 - 160

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

Torque: 44 N-m (440 kgf.cm, 31 ft.lb.)

- Reconnect the oxygen sensor connectors.
