I think you have a 5.5 so two sensors on bank2 [radiator side] , one on the header and one After the pre cat, the fsm has a brief procedure to follow checking off certian things before you throw your wallet at someone (stealership)or(dept store ase techs)
Possible Causes
1.Pre cat "just gut it"
2.exhaust leaks,
3.intake air leaks
And others like injectors,injector leaks,spark plugs and or timing.
I had this p0420 code when i first got my car so a friend that owns a shop deleted my main cat, changed my stock y from another maxima his "friend" sold him from his scrapyard ,it was in waaaay better shape than mine since it had lot less miles and the previous owner was a nancy filling up pure 97octane. Found receipts, now i do the same but only 93oct from a station with individual hose for the premium
