Fuel gauge stuck on full

[Chris08LTD]

I filled up my 98 Expy EB last week and I noticed that my gas gauge haven't moved down from full. Also there is a "C O" code from the overhead console. Any opinion about this guys? Thanks..

dont know what the co means but your sending unit in your tank could be shorting and causeing to read full all the time.

No idea what CO means, but I was also thinking that it could be the sending unit.

or, your truck was previously owned by IHOP and your gas keeps refilling by itself! lol. sorry, couldnt help myself. i agree, sounds like sending unit.

Thanks for the replies.. I'll definitely check it out on my days off. It just drives me nuts not knowing how much fuel I have in the tank.

Just reset your tripmeter next time you refill. Not sure what your MPG was, but I'd start looking for a refill when you start nearing 300 miles. Granted, that would depend on how big your tank is.

Guys, before I proceed on this project. Does anybody know how hard/easy this would be? Any tips? Thanks..
