get a new o2 sensor
After I get a new o2 sensor, would the o2 sensor I have to replace be in front of the cat behind the header?
go to this website . it tell you about this code .

you either need a pre cat o2
or you got worse . electrical problems .
you could do a simple few tests to determine I'f you need a new sensor or I'f it's the wiring . that's I'f you have a volt meter .
or you could just replace your pre cat o2 and see I'f that fixes it .

This. I would just replace both sensors if you're gonna do it. May as well.
why would you replace both ....
that's big money .
it's clearly putting a code for the pre cat 02 sensor .
there is no need to replace the post cat u2

The universal fit are $40-50. In my opinion, it's just worth it to do both at that price!
I had my post cat go out, and like 2 weeks later, my pre-cat. Since then, I would just do both at the same time. Once again, just me though.
Its alright guys the CEL went away by itself so I haven't done anything about it.
Nothing at all just kept driving it daily and it went away.
That's probably true
