Should be a fuse for OXYSENS one of the old sensors may have shorted and blown it, should be in the underhood power center. If it is ok, you may need to take it to a shop to be put on a scanner so they can command them to work to see which one is th eproblem

Although the fuse looked ok, I replaced it and I haven't got that error. Thank you!
