. Thanks in advance. It is a 2003 w/ an I6 engine.
I had the same issue with my 99 TJ it turned out to be a 5 cent fuse that had blown once replaced the code went away. not saying this is your problem have you cleared the code from the computer?
I will have to look tonight in the service manual to tell you what one I replaced but it was in the under hood fuse box not the one inside. i think it was a 10 i replaced. but I know the title said nothing about O2 sensor I had to look at a wiring diagram to figure out where the fuse was.
