I got my first MIL yesterday: bank 2 O2 sensor 2 voltage too high. Does this mean the O2 is shot, or did I rewire it wrong?

 

what do you mean rewire it wrong

why were you rewiring your O2 sensor

 

Because he had to relocate the rear o2 sensors because he removed his precats, all of them. So that means he probably moved them behind the main cat.

Pimp, just remember that this MIL doesnt affect engine performance at all.

Yeah, the O2 sensors were moved behind the main cat. The shop rewired them for me with shielded wire, but they must have mixed them up. I hooked the car up to the scan tool and it shows a constant voltage. I'll have to check it out.

Thanks Dixit

 

i see

well if a shop did it take it back and tell them to fix it
