Installation [04/2018 - ]: Procedure

HINT: 

Perform "Inspection After Repair" after replacing the air fuel ratio sensor.

Refer to INITIALIZATION [04/2018 - 08/2019] , or refer to INITIALIZATION [08/2019 - ]

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

   *a	Torque Wrench Fulcrum Length

   • SST: 09224-00012 

   Specified tightening torque 

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

   NOTE:

   If the air fuel ratio 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 [04/2018 - ]

   • 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. Engage the 2 wire harness clamps.
3. Connect the air fuel ratio sensor connector.
