The car ran out of gas. What does it show?

When the car runs out of fuel, it will light the fuel indicator to remind the driver that the remaining fuel is monitored by the float sensor in the fuel tank. After the sensor monitors the fuel position, it will feed back the signal to the ECU, and the ECU will feed back the signal to the dashboard through all-round analysis. If the fuel quantity is too low, the fuel indicator will light up. There are pointer and electronic fuel lamps with letters F and E at both ends. Pointing to F means that the tank is full, pointing to E means that the tank is empty, and pointing to the middle means that the tank is still half full. Under normal circumstances, after the indicator light gives an alarm, the vehicle can still travel 50 to 90 kilometers under normal road conditions, but it is not good for the fuel pump to dissipate heat after driving, so it is not recommended to drive like this unless there are special circumstances.
