NOTE:
- When outputting DTC P0420 replace the exhaust manifold sub-assembly RH (*1) and the front exhaust pipe assembly (*3) together when catalysts replacement is necessary. (Excluding air fuel ratio sensor *5 and heated oxygen sensor *7)
- When outputting DTC P0430 replace the exhaust manifold sub-assembly LH (*2) and the front exhaust pipe assembly (*3) together when catalysts replacement is necessary. (Excluding air fuel ratio sensor *6 and heated oxygen sensor *8)
