new to this forum-Chevy Aveo hold button flashing

[rubengomez]

Chevy Aveo 2006
I have a chevy Aveo with about 100K miles yesterday the check engine light came on and we checked it with a Craftsman OBD2 scan tool. The tool gave code P0131 O2 circuit low voltage (bank 1 sensor). I cleared the diagnostic code yesterday (I was going to replace the o2 sensor this weekend) and the next day it had the EVAP system light flashing ( I guess it had not re-set) and it in the morning when I first started the car the hold light was flashing and it seem as it was stuck in high gear, I drove it a few miles and the problem went away but it came back with the hold light flashing again. Does anyone know if the O2 sensor would be the cause of this problem? Also we had been having some issues when we turned the car on to warm up (about 3 min before taking off) the car would seem as it was accelerating it showed higher RPMS, not sure if it is relevant.
thanks,
Ruben
