These just popped up today, the first code is a o2 sensor heater bank 1 sensor 2 but already getting that worked on. Just wondering what I need to do for these evap codes

 

Those codes are likely related, they are both from the evap system, which is what allows fuel tank to breath as the fuel level changes. The vapor that comes of gasoline has to be captured and then it goes thru the engine to burn it. It looks 6our purge valve is probably malfunctioning for some reason. Could be something like a crqked vacuum hose or it could be the gas cap is not sealing tight? But it's not related to the heating element on the O2 sensor. I am not sure the detas of your car, or I would try to point you where to start lookimg

I took a closer look and a hose was loose and the clamp was not fully closed so hoping that’s the issue, going to get the o2 sensor today. I’ll clear codes after and go for a drive and see if it pops up. Thanks!
