PROCEDURE
INSTALL AIR FUEL RATIO SENSOR (for Bank 1)
Using SST, install the air fuel ratio sensor to the exhaust manifold sub-assembly RH (TWC: Front Catalyst).
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.
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)
INSTALL EXHAUST MANIFOLD SUB-ASSEMBLY RH
INSTALL AIR FUEL RATIO SENSOR (for Bank 2)
Using SST, install the air fuel ratio sensor to the exhaust manifold sub-assembly LH (TWC: Front Catalyst).
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.
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)
Engage the 2 clamps.
Connect the air fuel ratio sensor connector.
