Oxygen Sensor: Testing and Inspection
INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSORSHeated Oxygen Sensor (Bank 1, Sensor 1, Bank 2 Sensor 1)
- 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: 44 Nm (440 kgf.cm, 31 ft.lb)
- Reconnect the oxygen sensor connector.
Heated Oxygen Sensor (Bank 1 Sensor 2)
- Remove the passenger's seat.
- Take out the console box side of the floor carpet.
- 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: 44 Nm (440 kgf.cm, 31 ft.lb)
- Reconnect the oxygen sensor connector.
- Reinstall the floor carpet.
- Reinstall the passenger's seat.
