Installation [09/2014 - 10/2015]: Procedure
WARNING: This page is about a different car, the 2015 Lexus GS 350. However, it is still accessible from the selected car via links, so may be relevant.
- INSTALL AIR FUEL RATIO SENSOR
- for Bank 2 Sensor 1:
Using SST, install the air fuel ratio sensor to the exhaust manifold LH.
- SST: 09224-00010
without SST
Torque: 44 N*m (449 kgf*cm, 32 ft.*lbf)
with SST
Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf)
TEXT IN ILLUSTRATION*A for 2WD *B for AWD *1 Fulcrum Length HINT:
- Use a torque wrench with a fulcrum length of 300 mm (11.8 in.). When using a torque wrench with a fulcrum 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 (Refer to PRECAUTION [09/2014 - 10/2015] ).
- Make sure SST and the wrench are connected in a straight line.
- Perform "Inspection After Repairs" after replacing the air fuel ratio sensor (Refer to INITIALIZATION [09/2014 - 10/2015] ).
- for Bank 1 Sensor 1:
Using SST, install the air fuel ratio sensor to the exhaust manifold RH.
- SST: 09224-00010
without SST
Torque: 44 N*m (449 kgf*cm, 32 ft.*lbf)
with SST
Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf)
TEXT IN ILLUSTRATION*1 Fulcrum Length HINT:
- Use a torque wrench with a fulcrum length of 300 mm (11.8 in.). When using a torque wrench with a fulcrum 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 (Refer to PRECAUTION [09/2014 - 10/2015] ).
- Make sure SST and the wrench are connected in a straight line.
- Perform "Inspection After Repairs" after replacing the air fuel ratio sensor (Refer to INITIALIZATION [09/2014 - 10/2015] ).
- Attach the 2 wire harness clamps.
