Bank 1 and 2 Sensor 1

HEATED OXYGEN SENSORS INSPECTION

1. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSORS (BANK 1, 2 SENSOR 1)
(a) Disconnect the 2 oxygen sensor connectors.





(b) Using an ohmmeter measure the resistance between terminals +B and HT.

Resistance: 11 - 16 Ohm at 20°C (68°F):

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

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

(c) Reconnect the 2 oxygen sensor connectors.
