I've been running a SES light with the code P0420 for over a year now. Car runs fine but I'm tired of looking at the light and people asking me is something wrong with my car when they're in it. From my research I have a bad 02 sensor in bank 1. I was looking on ebay and found one. I wanted to know if this one is the one I need. Any help will be appreciated..

Nevermind. I'm gonna get a new cat and see if that fixes the problem..
