I already change the two sensors oxyen of the cars but the light it's always on and sometimes the light of abs put on only for a while.
that's in the box of the fuse, i have to check i tell you tomorrow thank you for your time...

If the codes show that the O2 sensor(s) are causing the problem and the fuse is OK, I'd replace both the up and downstream.
