2. Using SST, tighten the sensor.
  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)
  
  HINT:
  - Use a torque wrench with a fulcrum length of 300 mm (11.8 in.). If using a torque wrench with a length that is not 300 mm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification (See PRECAUTION ).
  - Make sure SST and the wrench are connected in a straight line.
