Fuel Level Sensor A Stuck
Fuel level sensor A (typically the float in the main fuel tank section) reports a value that does not change over a long driving distance — the float is mechanically stuck against the tank wall, baffle or pump module. Without level changes the EVAP monitor cannot run and remaining-range estimates are wrong.
