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:
At 20°C (68°F)11 - 16 W
At 800°C (1,472°F)23 - 32 W
If the resistance is not as specified, replace the sensor.
Torque: 44 N´m (450 kgf´cm, 32 ft´lbf)
(d) Reconnect the oxygen sensor connector.
(e) Reinstall the passenger's seat.
