why does the fuel gauge require a button push to show the fuel level
1. First of all, we understand how the oil gauge displays the oil quantity. It is connected by a floating ball in the oil tank and a metal rod. The position of the floating ball on the oil level in the oil tank will also change through the metal rod;And this variable resistance will be connected to the fuel gauge of the vehicle, and the action of the fuel gauge pointer will be controlled by the magnitude of the current flow through the variable resistance.
2. In the case of some old cars, it is likely that the oil float is the problem. The oil float is also known as the oil level sensor.
3. If there is no problem with the oil level sensor, it is likely that there is a problem with the oil gauge circuit of the instrument panel. At this time, the instrument panel should be removed, and the multimeter and pin should be used to find the corresponding oil gauge circuit on the instrument for detection.
4. If the fuel gauge of the new car suddenly drops to zero and then does not move, it indicates that there is a problem with the sensor. You can directly replace it with the 4S store.
The fuel gauge is an indicator that can display the fuel quantity on the engine, and is displayed with a pointer or a number. Therefore, at present, automobile fuel gauges are mainly divided into digital fuel gauges and pointer fuel gauges.Most of the digital display fuel meters are equipped with LED display for easy viewing. The fuel meter has six major functions, and each of these six functions is indispensable, otherwise it will be difficult for the owner to drive the car. The owner can decide whether to refuel according to the remaining fuel in the fuel tank displayed by the fuel gauge.The fuel gauge not only serves as a scale, but also can more advanced and accurately display the fuel consumption per kilometer and the fuel consumption of the vehicle, and whether the fuel is saved. The fuel gauge will also remind the owner of the remaining fuel and the range of the vehicle.If the owner fails to refuel in time, once the fuel storage is lower than a certain value, the fuel gauge of the vehicle will display the fuel alarm function. In addition, the car fuel gauge can even display the car's odometer and store three months of real-time measurement data for data management.
