What Causes the Car Fuel Gauge Not to Display?
1 Answers
The reasons for the fuel gauge not displaying: malfunction of the fuel float (fuel level sensor); short circuit in the fuel gauge wiring, etc. Malfunction of the fuel float (fuel level sensor): For older cars, this is likely an issue with the fuel float, also known as the fuel level sensor by car owners. The owner can check if the fuel level sensor plug on the fuel tank is loose, oxidized, or burnt; observe whether there is any obstruction in the sliding process of the fuel level sensor. Short circuit in the fuel gauge wiring: If the fuel level sensor is functioning properly, the issue might lie in the fuel gauge wiring on the dashboard. In this case, the dashboard should be removed, and a multimeter and a pin can be used to locate and test the corresponding fuel gauge wiring on the dashboard.
