REMOVAL

1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.

2. REMOVE HEATED OXYGEN SENSOR (for Bank 1 Sensor 2)
a. Disconnect the sensor connector under the center console.




b. Using SST, remove the heated oxygen sensor.

SST 09224-00010

3. REMOVE FRONT EXHAUST PIPE ASSEMBLY
a. Disconnect the heated oxygen sensor (for Bank 2 Sensor 2) connector.




b. Remove the 2 bolts and 2 compression springs.




c. Remove the 6 nuts and front exhaust pipe assembly.

4. REMOVE HEATED OXYGEN SENSOR (for Bank 2 Sensor 2)




a. Using SST, remove the heated oxygen sensor from the front exhaust pipe assembly.

SST 09224-00010

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, 30 ft. lbs.) for use with SST
44 Nm (449 kgf.cm, 32 ft. lbs.)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.

NOTE:
- 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, 46 ft. lbs.)




e. Install the front exhaust pipe assembly with the 2 compression springs and 2 bolts.

Torque: 43 Nm (438 kgf.cm, 32 ft. lbs.)

f. Install the No. 1 exhaust pipe support bracket with 2 new nuts.

Torque: 21 Nm (214 kgf.cm, 15 ft. lbs.)




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, 30 ft. lbs.) for use with SST
44 Nm (449 kgf.cm, 32 ft. lbs.) 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.

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

4. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
5. INSPECT FOR EXHAUST GAS LEAK
