Heated Oxygen Sensors Inspection

1. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSORS (BANK1, 2 SENSOR1)
- Disconnect the 2 oxygen sensor connectors.
- Using an ohmmeter, measure the resistance between terminals +B and HT.

Resistance: At 20°C (68°F): 11 - 160hms

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

Torque: 44 N.m (450 kgf.cm, 33 ft.lb.)

- Reconnect the 2 oxygen sensor connectors.
