   1. 

      *a	Torque Wrench Fulcrum Length

      Using SST, install the air fuel ratio sensor to the exhaust manifold converter sub-assembly (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
