Codes p0420 p1111 car runs fine no problem but light is on. About 2 years ago I had to replace hose about 8 to 10 inches at top under hood. But I checked this hose and it looks good. Before this light I smelled fumes for a long time. I'm a disabled vet and can't afford to take it to dealer

P0420 is catalyst below efficiency bank 1. This could be the catalytic convertor needs replacing
