Heated Oxygen Sensor (Bank 1 Sensor 2)

COMPONENTS

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: See "Related Diagnostic Charts" in this section
