Check eng light trouble code PO420 bank 1 on toyota camry 2002 le replaced top oxygen sensor reset codes and check eng. light came back on.

More often than not the Cat is bad. Replacing the sensors is the easiest move. Reasons for the cat to go bad will be related to something else wrong with the fuel management and emissions systems in the car, improper sealants or chemicals used on prior repairs causing damage to the cat

Bank #2 referes to the side of the eng in which cyl. #2 is snsr #1 referes to the sensor before the cat. conv. and the code is for a slow response so, basically a lazy O2 snsr. So if you can locate cyl. #2 and follow the exaust manifold on that side of eng. the very first O2 snsr you see is the one in need of diag./repair

I think you will find the aftermarket Cat Conv. is the source of your problem, but without hooking up to the factory test equipment at my disposal at my Ford dealer this at best and educated guess based on 20 years of emission related work, I am a Ford certified master electronics technician
