: evil: My 2001 Nissan Maxima is needing it's 2nd cat converter fixed. I want to be sure I'm getting the right ones fixed for the right reasons. Any help on parts and code readings will be appreciated.
Already had part SPO 20020-3Y400 (one cat converter)
Now i've been told a code P0430 by Nissan and code P0420 by another mechanic.
What is the difference in the codes and NOW which cat should I be replacing? Nissan told me part # B08 A03Y102.
