Heated Oxygen Sensor

HEATED OXYGEN SENSOR

INSPECTION

1. INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR




a. Disconnect the sensor connector.
b. Using an ohmmeter, measure the resistance between terminals +B and HT.

Resistance:

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. Bank 1 Sensor 2:
