First time I really took the Ty out on a small road trip today. About 15 miles into it my cel light came on. I began checking all my gauges and noticed on my wideband it was a little over 10. Usually when cruising at 75 it's between 14-15. Seems to run fine but I don't know what would be causing this issue. I tried pulling the codes but all it gives me is a 12.Any ideas?
