Title: 2GR-FE (ENGINE CONTROL): AIR FUEL RATIO SENSOR: INSTALLATION; 2016 MY Sienna [12/2015 - 08/2016]

INSTALLATION

1. INSTALL NO. 2 AIR FUEL RATIO SENSOR (for Bank 1 Sensor 1)

(a) Using SST, install the No. 2 air fuel ratio sensor (for bank 1 sensor 1) to the exhaust manifold RH (TWC: front catalyst).

*a	Fulcrum Length of SST
*b	Fulcrum Length of Torque Wrench

SST: 09224-00010

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 No. 2 air fuel ratio sensor (for bank 1 sensor 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.)): 40 N*m (408 kgf*cm, 30 ft.*lbf).

2. INSTALL EXHAUST MANIFOLD TO HEAD GASKET

3. INSTALL EXHAUST MANIFOLD SUB-ASSEMBLY RH

4. INSTALL MANIFOLD STAY

5. INSTALL FRONT EXHAUST PIPE ASSEMBLY (for 2WD)

6. INSTALL FRONT EXHAUST PIPE ASSEMBLY (for AWD)

7. INSTALL PROPELLER WITH CENTER BEARING SHAFT ASSEMBLY (for AWD)

(See page )

8. INSTALL NO. 2 ENGINE UNDER COVER (for AWD)

9. INSTALL NO. 1 ENGINE UNDER COVER

10. INSTALL AIR FUEL RATIO SENSOR (for Bank 2 Sensor 1)

(a) Using SST, install the air fuel ratio sensor (for bank 2 sensor 1) to the exhaust manifold LH (TWC: front catalyst).

*a	Fulcrum Length of SST
*b	Fulcrum Length of Torque Wrench

SST: 09224-00010

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 air fuel ratio sensor (for bank 2 sensor 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.)): 40 N*m (408 kgf*cm, 30 ft.*lbf).

(b) Connect the air fuel ratio sensor (for bank 2 sensor 1) connector.

(c) Engage the 3 clamps to connect the air fuel ratio sensor (for bank 2 sensor 1) connector to the wire harness clamp bracket and 2 case clamps.

11. INSPECT FOR EXHAUST GAS LEAK

12. INSTALL V-BANK COVER SUB-ASSEMBLY

13. INSTALL AIR CLEANER INLET COVER ASSEMBLY SEAL
