Title: 2GR-FKS (ENGINE CONTROL): HEATED OXYGEN SENSOR: INSTALLATION; 2017 - 2020 MY Sienna [08/2016 - ] |
INSTALLATION
PROCEDURE
1. INSTALL HEATED OXYGEN SENSOR (for Bank 1)
(a) for 2WD:
(1) Using SST, install the heated oxygen sensor (for bank 1) to the front exhaust pipe assembly.
SST: 09224-00012
Torque:
Specified tightening torque :
44 N·m {449 kgf·cm, 32 ft·lbf}
NOTICE:
If a component has been dropped or subjected to a strong impact, replace heated oxygen sensor (for bank 1).

(b) for AWD:
(1) Using SST, install the heated oxygen sensor (for bank 1) to the No. 3 exhaust pipe sub-assembly.
SST: 09224-00012
Torque:
Specified tightening torque :
44 N·m {449 kgf·cm, 32 ft·lbf}
NOTICE:
If a component has been dropped or subjected to a strong impact, replace heated oxygen sensor (for bank 1).
HINT:
-
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench (See page
).
-
When using SST (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 300 mm (11.8 in.)): 39 N*m (398 kgf*cm, 29 ft.*lbf).
