Computer problem
2006 Chevy Malibu 4 cyl Two Wheel Drive Automatic 36000 miles

The check engine light came on, and I had the car checked to see why. The computer said, "Voltage signal from fuel level sensor is intermittent." I am wondering what exactly that means and how much it will cost me to fix it, or if I even need to fix it. Thank you.

Does fuel gague work? Car run good then you could ignore

Yes, fuel gage works. Thank you for your help.
