    1. B0070CZC01
      *a Torque Wrench Fulcrum Length

      Using SST, install the air fuel ratio sensor to the exhaust manifold (TWC: Front Catalyst).

      SST
      09224-00012
      Torque:
      Specified tightening torque
      44 N*m  { 449 kgf*cm, 32 ft.*lbf }

      Note

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

      Tech Tips


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