In the recalled vehicles, that valve might have stuck open, and the powertrain control module in charge of looking for a stuck-open valve may have malfunctioned. If both problems occurred, excessive vacuum might have deformed the fuel tank, which could cause the fuel gauge to act up or stall the vehRead More – Source
