2GR-FE EMISSION CONTROL: HEATED OXYGEN SENSOR (for 2WD): INSTALLATION

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 Nm (408 kgf-cm, 30ft-lbf)for use with SST
Torque: 44 Nm (449 kgf-cm, 32ft-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:
- Be careful with the installation direction of the gasket.
- Do not damage the gasket.
- Do not reuse the gasket.
- To ensure a proper seal, do not use the exhaust pipe to force the gasket on to 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 Nm (632 kgf-cm, 46ft-lbf)









(e) Install the front exhaust pipe assembly with the 2 compression springs and 2 bolts.
Torque: 43 Nm (438 kgf-cm, 32ft-lbf)
(f) Install the No. 1 exhaust pipe support bracket with 2 new nuts.
Torque: 21 Nm (214 kgf-cm, 15ft-lbf)





(g) Connect the heated oxygen sensor (for Bank 2 sensor 2) connector.
3. INSTALL HEATED OXYGEN SENSOR (for Bank 1 Sensor 2)





(a) Using SST, install the heated oxygen sensor.
SST: 09224-00010
Torque: 40 Nm (408 kgf-cm, 30ft-lbf)for use with SST
Torque: 44 Nm (449 kgf-cm, 32ft-lbf)for use without SST

NOTICE:
- 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.

(b) Connect the heated oxygen sensor (for Bank 1 Sensor 2) connector.
