Sometimes it does sometimes not. Just to be sure, go back to autozone and have them clear it. But if your o2 sensor is bad then its gonna come on again. I would just get an o2 sensor(the one that I could afford) and replace it. And yes its always good to change that pcv valve. It will cause more problems than you would believe. You can get a scan tool at wal mart for 89.00. Even cheaper than that if you do a search online. Good luck let me know whats going on
