Toyota Sienna Service Manual: Inspection
1. INSPECT HEATED OXYGEN SENSOR (for Bank 1 Sensor 2)
(a) Measure the resistance of the sensor.
Standard resistance
If the resistance is not as specified, replace the sensor.
2. INSPECT HEATED OXYGEN SENSOR (for Bank 2 Sensor 2)
(a) Measure the resistance of the sensor.
Standard resistance
If the resistance is not as specified, replace the sensor.
Installation
1. INSTALL HEATED OXYGEN SENSOR (for Bank 2 Sensor 2)
(a) Using SST, install the heated oxygen sensor to the front exhaust pipe.
SST 09224-00010
Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf) for use with SST 44 N*m (449 kgf*cm, 32 ft.*lbf) for use without SST
HINT:
- Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
- Make sure that SST and a wrench are connected in a straight line.
2. INSTALL FRONT EXHAUST PIPE ASSEMBLY
(a) Check the compression springs.
(1) Check the compression springs using vernier calipers
Specified length: 38.86 mm (1.5299 in.)
HINT: If the result is not as specified, replace the compression spring.
(b) Install the gasket.
(1) Install a new gasket by hand onto the front exhaust pipe assembly.
(2) Using a plastic hammer and wooden block, tap in the new gasket until its surface is flush with the front exhaust pipe.

(c) Install 2 new gaskets to the front exhaust pipe assembly.
(d) Install the front exhaust pipe assembly with the 4 nuts.
Torque: 62 N*m (632 kgf*cm, 46 ft.*lbf)
(e) Install the front exhaust pipe assembly with the 2 compression springs and 2 bolts.
Torque: 43 N*m (438 kgf*cm, 32 ft.*lbf) (f) Install the No. 1 exhaust pipe support bracket with 2 new nuts.
Torque: 21 N*m (214 kgf*cm, 15 ft.*lbf)
(g) Connect the heated oxygen sensor (for Bank 2 sensor 2) connector.
