Heated Oxygen Sensor

HEATED OXYGEN SENSOR (Bank 1 Sensor 2)

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 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
