I had a check engine light come on and the warning is OBD P0158 which I have got from a meter and since read that it is an over voltage error on the rear left Oxygen sensor behind the CAT converter. If this is not correct please let me know.

Is this common or should I pull it out and replace it?

common problem.. O2 sensor need to be replaced and ECU probably needs a software update. I dont think you will see any difference in gas milage, but you could get into trouble when time for inspection.
