just got my car back from the mechanic, got both pre-cat o2 sensors replaced and an oil change, now I'm getting an error code
"2DED - DME: power management, closed-circuit current violation" could this have something to do with the o2 sensors? what does this mean?

It would be difficult to relate that code to the O2 sensors. It means that you have a parasitic draw over the established level when the car started at some point. I would clear the code and see if it returns. I could just have been in the course of disconnecting the battery, assuming they did that. That tends to produce transient codes that don't stick around.
