This kind of oil meter failure phenomenon is more common. Under normal circumstances, the fuel gauge of many models in the first half will drop more slowly, and after passing the middle scale, it will drop faster. This is mainly related to the design of the oil pump used to reflect the amount of oil. It cannot evenly reflect the change in gasoline consumption. After all, this absolute constant speed change is difficult to achieve, and it is not easy to change through maintenance and replacement of parts.

Check whether the appearance of the faulty part of the sensor is obviously damaged, whether the connector is damaged and whether the float can slide normally.

The fuel level measurement relies on the fuel level detection system composed of the fuel level sensor and the fuel gauge. The oil level sensor, usually called the oil float, is a sensing device for the fuel level. It uses the change of the capacitance between the sensor housing and the induction electrode after the oil enters the container, and converts this change into a current change to detect the position (height) of the oil in the container.

With the development of science and technology, intelligent automobile has become a trend. Among them, smart car sensors play a vital role. They are the eyes, ears and nose of smart cars, which can sense the surrounding environment and provide real-time information to the vehicle to ensure driving safety.

There is no doubt that cars are one of the necessities for people to travel. With the vigorous development of 5G and intelligent networking, the world has entered the era of the Internet of Everything, and smart cars and driverless are rapidly becoming the hallmarks of the new travel era. Subsequently, the performance of smart cars needs to be continuously improved and optimized, which must benefit from the rapid development of automotive electronic technology, and the most representative core component is MEMS automotive sensors.
