NOTE:
- If DTC P0420-00 is output, replace the exhaust manifold (*6) and the center exhaust pipe assembly (*10) 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 assembly LH (*7) and the center exhaust pipe assembly (*10) together when catalyst replacement is necessary (Excluding air fuel ratio sensor*2 and heated oxygen sensor*4).
