REMOVAL
PROCEDURE
1. REMOVE INSTRUMENT PANEL FINISH PANEL END LH
|
(a) Using a clip remover, remove the clip. |
|
(b) Disengage the 3 guides and remove the instrument panel finish panel end LH.
2. REMOVE TAIL EXHAUST PIPE ASSEMBLY
|
(a) Remove the 2 bolts to separate the tail exhaust pipe assembly from the center exhaust pipe assembly. |
|
|
(b) Disconnect the 4 exhaust pipe supports to remove the tail exhaust pipe assembly from the vehicle. |
|
(c) Remove the gasket from the center exhaust pipe assembly.
3. REMOVE CENTER EXHAUST PIPE ASSEMBLY
|
(a) Disconnect the oxygen sensor (for bank 1 sensor 2) connector. |
|
(b) Remove the oxygen sensor (for bank 1 sensor 2) wire grommet and pass the connector through the hole to the outside of the vehicle.
|
(c) Disengage the clamp to disconnect the oxygen sensor (for bank 1 sensor 2) wire from the vehicle. |
|
|
(d) Remove the 2 bolts and 2 nuts to separate the center exhaust pipe sub-assembly from the front exhaust pipe assembly and exhaust manifold sub-assembly RH (TWC: front catalyst). |
|
|
(e) Disconnect the 2 exhaust pipe supports to remove the center exhaust pipe assembly from the vehicle. |
|
(f) Remove the 2 gaskets from the center exhaust pipe assembly and front exhaust pipe assembly.
|
(g) Remove the 2 bolts and 2 compression springs to remove the center exhaust pipe sub-assembly (TWC: rear catalyst) from the front No. 3 exhaust pipe sub-assembly. |
|
(h) Remove the 2 bolts and 2 compression springs to remove the center exhaust pipe sub-assembly (TWC: rear catalyst) from the center No. 2 exhaust pipe sub-assembly.
(i) Remove the 2 gaskets from the front No. 3 exhaust pipe sub-assembly and center exhaust pipe sub-assembly.
4. REMOVE FRONT EXHAUST PIPE ASSEMBLY
|
(a) Disconnect the oxygen sensor (for bank 2 sensor 2) connector. |

|
|
(c) Loosen the bolt and separate the exhaust pipe clamp from the No. 1 exhaust pipe support bracket. |
|
|
(d) Remove the 2 nuts and front exhaust pipe assembly from the exhaust manifold sub-assembly LH (TWC: front catalyst). |
|
(e) Remove the gasket from the front exhaust pipe assembly.
5. REMOVE OXYGEN SENSOR (for Bank 1 Sensor 2)
|
(a) Using SST, remove the oxygen sensor (for bank 1 sensor 2) from the front No. 3 exhaust pipe sub-assembly. SST: 09224-00010 NOTICE: If a component has been dropped or subjected to a strong impact, replace oxygen sensor (for bank 1 sensor 2). |
|
6. REMOVE NO. 2 OXYGEN SENSOR (for Bank 2 Sensor 2)
|
(a) Using SST, remove the No. 2 oxygen sensor (for bank 2 sensor 2) from the front exhaust pipe assembly. SST: 09224-00010 NOTICE: If a component has been dropped or subjected to a strong impact, replace No. 2 oxygen sensor (for bank 2 sensor 2). |
