My fuel gauge does not read right when it is below zero
on 2004 Buick LeSabre

My fuel gauge acts up when it is zero or below. It will generally read fuller than it is, but when the weather is above zero it seems to be okay. What do you think? Ground? Faulty sensor?

Where?
In my opinion it will be the sending unit.
