Oxygen Sensors Inspection

1. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSORS.
(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 (31 ft.lb)

- Reconnect the oxygen sensor connector.


2. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR.
(BANK 1, SENSOR 2)



- Floor shift: Take out the console box side of the floor carpet.
- Column shift: Remove the passenger's seat.

- Disconnect the oxygen sensor connector.
- Using an ohmmeter, measure the resistance between the terminals +B and HT.

Resistance At 2O°C (68°F): 11 - 16 Ohms

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

Torque: 44 Nm (31 ft.lb)

- Reconnect the oxygen sensor connector.

- Floor shift: Reinstall the floor carpet.
- Column shift: Reinstall the passenger's seat.
