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.
NOTICE:
|
(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.

Mass or Volume Air Flow Circuit High Input
DESCRIPTION
The Mass Air Flow (MAF) meter is a sensor that measures the amount of air
flowing through the throttle
valve. The ECM uses this information to determine the fuel injection time and to
provide appropriate airfuel
ratio. Inside the MAF meter, there is a heated platinum wire which is ...
