Bad O2 sensor perhaps ?

I have 08 Yaris HB , 30xxx mi on the odo, supercharged with aftermarket adds on. 17" wheels and Use a/c all the time and still getting 33-36 mpg..... That's with an O2 sensor CEL code tho ... (ordered the new part n waiting to arrive)

If the lambda sensor was off I imagine I'd see funny long term fuel trim numbers due to discrepancy between lambda and MAF sensors.
