No, this isn't a O2 sensor problem. One thing for sure, is that the car isn't running at 11 AFR so you've probably got two (2) things wrong - 1st) the O2 sensor isn't calibrated for the type in the ECU config/tune (under tools, Calibrate AFR Table).
And 2nd) the tune or something within the ECU is thinking the AFR Table is 14, or the MAP or RPM is pointing to a cell that is always 14.... so you could plug a laptop into the car and switch to the AFR Table and watch that it is moving all over the table with the RPM revving in neutral. You can also add the AFR Target to the displayed guage or indicator in the dashboard to see what actual value the ECU is thinking it is targeting.
Try those things and focus on the AFR table being reported correct before you worry about the O2 sensor being correct/accurate.
