Hi guys ! I just came back from a road trip and the light "Service engine soon" suddenly appeared. Back at home, I checked which code came out (thanks to you guys for telling me how!) and it was P046 which means : Right to Left Bank Fueling Difference

Do you have any idea what it could be ?!
Thanks again for your help !!

Peace !!
Did you ever find out what was causing this?
