Default O2 sensor fault codes

OK, so my CEL popped on a few weeks ago and I finally got around to getting it scanned, and this is what showed up:

1) O2 sensor heater circuit malfunction
2) O2 sensor high volts

Anybody know the cheapest and easiest way to fix this.... I have also been having low idling problems for a little while now as well. Any help is greatly appreciated and thanks in advance.
