Heated Oxygen Sensor: Installation

INSTALL HEATED OXYGEN SENSOR (for 4WD)
1. Using SST, install the heated oxygen sensor.
  SST 09224-00010
  
  Torque: without SST
  
  44 N*m (449 kgf*cm, 32 ft.*lbf)
  
  with SST

  NOTE:
  - This torque value can be obtained by using a torque wrench with a fulcrum length of 300 mm (11.8 in.) and SST with a measurement of 30 mm (1.18 in.) (See REPAIR INSTRUCTION ).
  - This torque value is effective when SST is parallel to the torque wrench.
2. Connect the wire harness grommet.
3. Connect the heated oxygen sensor connector.
