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).

HINT:

  • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench (See page 2017 - 2020 MY Sienna [08/2016 -        ]; INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION ).
  • When using SST (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 255 mm (10.0 in.)):

    39 N*m (398 kgf*cm, 29 ft.*lbf)

(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).
