Heated Oxygen Sensor

HEATED OXYGEN SENSOR

INSPECTION

1. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR (Bank 1 Sensor 2)




a. Disconnect the oxygen sensor connector.

Resistance:

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

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

Torque: 20 N.m (200 kgf.cm, 14 ft.lbf)

c. Reconnect the oxygen sensor connector.

2. INSPECT OPERATION OF HEATED OXYGEN SENSORS
