| *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 | Center Exhaust Pipe Assembly | *8 | Tail Exhaust Pipe Assembly RH |
| *9 | Tail Exhaust Pipe Assembly LH | *10 | Exhaust Manifold Sub-assembly RH |
| *11 | Exhaust Manifold Sub-assembly LH | *12 | Front Exhaust Pipe Assembly |
NOTE:
- When outputting DTC P0420 replace the exhaust manifold sub-assembly RH (*10) and the front exhaust pipe assembly (*12) together when catalyst replacement is necessary (Excluding air fuel ratio sensor *1 and heated oxygen sensor *3).
- When outputting DTC P0430 replace the exhaust manifold sub-assembly LH (*11) and the front exhaust pipe assembly (*12) together when catalyst replacement is necessary (Excluding air fuel ratio sensor *2 and heated oxygen sensor *4).
