      • SST: 09224-00012 

      Specified tightening torque 

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

      NOTE:

      If the heated oxygen 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 [12/2019 - 11/2023]

      • 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. INSTALL HEATED OXYGEN SENSOR (for Bank 1 AWD)
