Heated Oxygen Sensor: Inspection

INSPECT HEATER RESISTANCE OF HEATED OXYGEN SENSOR
1. Disconnect the oxygen sensor connector.
2. Using an ohmmeter, measure the resistance between terminals +B and HT.
  Resistance: 11 to 16 Ω 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)
3. Reconnect the oxygen sensor connector.
