Evap system code related to O2 sensor code?

Ok cuz it's also showing throttle pedal positioning sensor circuit low and I thought with these 3 having a common possible cause that maybe I'm not grounded where I should be or I'm getting a short somewhere that's causing these 3 codes. But I guess I'll have to inspect the wiring and run it down thank you.

I would say it's highly unlikely to be a common ground or short issue. These systems are quite independent of each other. If I were troubleshooting, I'd document codes, clear them, road test and see which ones come back. If they all come back right away, it would be best to start by checking into your oxygen sensor code first, then your throttle and evap codes. Heck, you could even have a software update that could improve all 3 -- but that's a wild guess. Yet, this is the benefit of having knowledgable, experienced professionals who are equipped with the essential diagnostic tooling that can do things that most of us can't do at home. Good luck!

Ok how do I do a software update or have one done? Sorry for all the questions and I appreciate your help

It’s all a guess. I’m just throwing out suggestions. There is no way to know anything unless you have proper diagnostic tooling that has access to General Motors software. This is going to be at a dealership or a high end trusted repair facility that has purchased the software. This is not a do it yourself situation. Yes, if you have shop manuals and some basic test equipment you can start doing circuit testing. But in the end you may run into a roadblock because cars require more sophisticated equipment for diagnosis and repair these days.
