IME a bad sending unit is the first step in your fuel pump going bad. It could be something else (I had a OBD2 port reader with a connection issue that would cause this CEL along with a CANBUS communication error), but if the car is under warranty, get it in and tested. If not, I'd run it until it dies- you can run with a bad sending unit for a LONG time and you'll be fine, it doesn't always mean that the fuel pump is screwed. Don't trust the fuel gauge, start using the trip odo instead
