Order of inspection
P0175 System Too Rich (Bank 2) Medium
The P0175 code means the computer had to pull fuel for a long time on bank 2 and used up its correction margin. It is the reverse of P0174 and is diagnosed with the same logic: compare both banks to learn whether the cause is common to the whole engine or local to that side.
