INSTALL AIR FUEL RATIO SENSOR
1. Using SST, install the air fuel ratio sensor to the exhaust manifold.
  SST 09224-00010
  
  Torque: without SST
  
  44 N*m (449 kgf*cm, 32 ft.*lbf)
  
  with SST
  
  40 N*m (408 kgf*cm, 30 ft.*lbf)
  NOTE:
  - The "with SST" torque value is effective when using SST with a fulcrum length of 30 mm (1.18 in.).
  - The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 300 mm (11.81 in.) (See REPAIR INSTRUCTION ).
  - This torque value is effective when SST is parallel to the torque wrench.
