Why does the fuel gauge show not full when the tank is actually full?
1 Answers
The reasons why the fuel gauge shows not full when the tank is actually full are as follows: Tank not actually full: The tank was not actually full to begin with. The reason the fuel nozzle stopped is because gasoline vapor caused the nozzle to stop automatically. Fuel pump problem: If the fuel gauge often shows not full after refueling, it indicates an internal vehicle issue. A common problem is a faulty float in the fuel pump. Fuel tank sensor problem: There may be an issue with the fuel tank sensor, which would require replacement. The fuel tank is divided into two sections: a main tank and a secondary tank. Each section has its own fuel level sensor, and the two sensors are connected in series. The fuel gauge displays the average of the remaining fuel in both sections. Poor contact between the main and secondary fuel level sensors can cause the above phenomenon.
