Default Wideband o2 sensor

I am unfamiliar with whether or not the gen 1 speed 3s come stock with a wideband o2 sensor. I have my accessport hooked up but it is not properly reading my AFRs. I don't know if I'm missing something or if could be the check engine light being on is why it is not reading afr. The check engine light is on for an o2 sensor but both sensors have been replaced by the dealer.

The stock upstream sensor is an air fuel sensor. If you have a check engine light on for an o2 issue start with that.
