vdo guage: fuel level sender when tank empty gauge says full, when tank full gauge says empty why?
The reason why the fuel tank is full but the fuel gauge shows dissatisfaction:
1. The fuel tank is not full, the reason why the fuel gun jumps is because the gasoline vapor jumps the top of the fuel gun;
2. If the fuel gauge is often filled up If the display is dissatisfied, it means that there is an internal problem in the car. It is common that there is a problem with the float of the fuel pump;
3. There is a problem with the sensor of the fuel tank. In this case, the sensor of the fuel tank needs to be replaced. The fuel tank is divided into two parts, one is the main fuel tank and the other is the auxiliary fuel tank, each part has its own fuel level gauge, and the two fuel level gauges are connected in series, the fuel gauge shows the average of the total remaining fuel in the two parts The above phenomenon occurs due to poor contact between the main oil level sensor and the auxiliary oil level sensor.
The solution to the dissatisfaction when the fuel tank is full:
1. The fuel tank is not fully filled. The reason why the fuel gun jumps is because the gasoline vapor "tops" the fuel gun;
2. If the fuel gauge shows dissatisfaction after filling up frequently, it means that there is a problem. The most common phenomenon is that there is a problem with the float of the oil pump. Solution: replace the oil pump;
3. Another situation is that there is a problem with the sensor of the fuel tank. This condition requires the sensor of the fuel tank to be replaced.
The reasons for the dissatisfaction when the fuel tank is filled up are:
1. Excessive refueling speed will generate expanding steam, and the gas from the gasoline will not be released in time when refueling; 2. There is a problem with the oil dipstick or the oil gun is placed too shallow. The method of opening the fuel tank is: 1. Use the key to open;
2. Press the fuel tank button in the car to open;
3. Press the fuel tank cover directly to open. The structure of the automobile fuel tank is composed of a fuel pipe, a tank body, a gasoline tank cover, a gasoline meter, and a gasoline fuel pump. Car fuel tanks are divided into different fuel tanks: gasoline tanks and diesel tanks. Automobile fuel tanks are divided into: bite fuel tanks, aluminum alloy fuel tanks, CO2 welded fuel tanks, upper and lower butted fuel tanks, and seam welded fuel tanks at both ends.
