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 to 16 ohms at 20 degree C (68 degree 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.
