INSPECTION




INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR (Bank 1 Sensor 2)
a. Remove the passenger's seat.
b. Disconnect the oxygen sensor connector.
c. Using an ohmmeter, measure the resistance between the terminals +B and HT.

Resistance:
11 - 16 Ohms at 20 °C (68 °F)
23 - 32 Ohms at 800 °C (1,472 °F)

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

Torque: 44 Nm (450 kg.cm, 32 ft.lb)

d. Reconnect the oxygen sensor connector.
e. Reinstall the passenger's seat.
