INSPECTION

1. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR
(a) Disconnect the oxygen sensor connector.





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

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

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

Torque: 44 N.m (450 kgf.cm, 32 ft.lbf)

(c) Reconnect the oxygen sensor connector.
2. INSPECT OPERATION OF HEATED OXYGEN SENSOR
