NOTE:
- If DTC P0420-00 is output, replace the exhaust manifold sub-assembly RH (*10) and the front exhaust pipe assembly (*7) together when catalyst replacement is necessary (Excluding air fuel ratio sensor*1 and heated oxygen sensor*3).
- If DTC P0430-00 is output, replace the exhaust manifold sub-assembly LH (*11) and the front exhaust pipe assembly (*7) together when catalyst replacement is necessary (Excluding air fuel ratio sensor*2 and heated oxygen sensor*4).
