INSPECTION

INSPECT HEATER RESISTANCE OF A/F SENSORS
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: 44 N.m (450 kg.cm, 32 ft.lb)

c. Reconnect the sensor connector.
