I put a front mount turbo kit on and my rear o2's are just hanging there for now. can I just unplug them and take them off, or will the computer know there unplugged?

 

They wont affect anything if they are unplugged. then just get them tuned out.

 

Yeah, I don't have a turbo or S/c, but I do have them tuned out.

 

I still have them plugged in and just wired up for now but my check engine light came on the other day and said my passenger rear o2 was reading low voltage. I have them tuned out so why is this still happening?

 

Double-check that tune.

 

tune thm out and unplug them I think they are B1S2 and B2s2 but don't hold me to that.

 

There are multiple DTC processing and MIL enablers for each of the rear 02 sensors.

Heater performance
Low voltage
High voltage
Insufficient activity

If you send me a copy of your tune, I can take a look at it.
