Catalyst Location
| *1 | Air Fuel Ratio Sensor (Bank 1 Sensor 1) | *2 | Air Fuel Ratio Sensor (Bank 2 Sensor 1) |
| *3 | Heated Oxygen Sensor (Bank 1 Sensor 2) | *4 | Heated Oxygen Sensor (Bank 2 Sensor 2) |
| *5 | TWC: Front Catalyst | *6 | TWC: Rear Catalyst |
| *7 | Exhaust Manifold Assembly RH | *8 | Exhaust Manifold Assembly LH |
| *9 | Front Exhaust Pipe Assembly | *10 | Center Exhaust Pipe Assembly |
| *11 | Tail Exhaust Pipe Assembly | - | - |
NOTE:
- If DTC P0420-00 is output, replace the exhaust manifold assembly RH (*7) and the center exhaust pipe assembly (*10) together when catalyst replacement is necessary (Excluding air fuel ratio sensor*1).
- If DTC P0430-00 is output, replace the exhaust manifold assembly LH (*8) and the center exhaust pipe assembly (*10) together when catalyst replacement is necessary (Excluding air fuel ratio sensor*2).
