Heated Oxygen Sensor

Heated Oxygen Sensor:

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 to 16 Ohm 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
