Okay so this is whats going on. My gas gauge goes to empty well i hooked my scan tool up no codes popped up so i hit clear and the damn gauge started working. But a couple seconds later would stop working again. Im at a loss at whats going on anybody have any ideas?

 

Most likely a bad sending unit.

 

thats what i was thinking but i yurndd off the truck cleared the codes and now it works fines im just mind blown #chevy****
