Got it connected and its reading it but I’m a bit confused by the two groups of error codes when I scroll down. On the first group of codes it only shows; “Error 131 O2 Low” and as I continue to scroll down to the another group of error codes which display error on a bunch of codes and this second group of errors fluctuate.
Does the rest of the data you're seeing make sense? e.g. is the reported RPM correct? If you see errors toggling on and off, most likely you're not getting correct data from the vehicle.
