Air Fuel Ratio Sensor

INSPECTION




INSPECT HEATER RESISTANCE OF A/F SENSORS
a. Disconnect the A/F sensor connector.
b. Using an ohmmeter measure the resistance between terminals +B and HT.

Resistance: 0.8 - 1.4 ohms at 20 °C (68 °F)
If the resistance is not as specified, replace the sensor.

Torque: 44 N.m (440 kgf.cm, 31 ft.lbf)

c. Reconnect the A/F sensor connector.
