      *a Torque Wrench Fulcrum Length
      • SST: 09224-00012 

      Specified tightening torque 

      Torque: 44 N.m (449 kgf/cm, 32 ft.lbf) 

      NOTE:

      If the air fuel ratio sensor has been struck or dropped, replace it.

      HINT: 

      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

        Refer to PRECAUTION [06/2018 - ]

      • When using SST (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)):

        37.7 N.m (384 kgf/cm, 28 ft.lbf)

    2. Engage the 2 wire harness clamps.
    3. Connect the air fuel ratio sensor connector.
  2. INSTALL AIR FUEL RATIO SENSOR (for Bank 2) 

    HINT:
