So I returned my deleted truck to stock and it’s now popping these Two codes. It has 140k on it. There is definitely DEF being injected after the cat I can smell it - there isn’t a diesel exhaust smell. I need to fix this in order to get an inspection sticker. The truck is also driving sluggish dunno if it’s related. Since I’ve returned to stock the truck has just been sitting in my driveway with these codes. I only took it for a five minute drive up and down my street. I’m stumped... I’ve checked all the connectors everything is connected and seated. Any advice or direction would be appreciated folks! Thanks!
