aftermarket "fuel level gauge" erratic fluctuating
1. Design: The line design scheme of the oil gauge of different vehicles is different, which also affects the inaccuracy of the oil gauge. Some are fast in the first half and slow in the second half, and some are slow in the first half and fast in the second half. If you confirm that it is full of fuel oil, or something like this occurs, you can go to the repair shop for debugging;
2. Sensor: This is also a device that directly affects the inaccuracy of the oil gauge. It reflects the obstruction of data transmission or the inaccuracy of transmission, which causes the oil gauge pointer to fail to reach the accurate reading position. This type of precision equipment can only be repaired by professional debugging equipment in the repair shop;
3. Display: The problem of oil surface display is the most widely encountered by car users, some of which are caused by the jam of the pointer or the impurities in the watch. This type of appearance is also caused by the accumulated dust over time. We can handle it by ourselves through cleaning measures, or you can provide maintenance through a professional repair shop.There is a situation where the oil gauge suddenly drops to zero, and the opposite is naturally a rise. And if it rises to a position, it will not rise again, and it will remain stationary.If this is the case, it proves that the connecting rod between the oil level sensor and the float is stuck, the float cannot float up and down normally, the sensor does not work, and the pointer is also fixed at a certain position.If the fuel gauge is inaccurate, when the car is used in an emergency, it will make a mistake because of being "deceived" by the fuel gauge.
It is also possible that when the new car is in the running-in period, the fuel gauge will fluctuate up and down. This phenomenon is very normal, but when the old car encounters such a situation, it is necessary to check it carefully. If the oil gauge scale is fast and slow, especially the first half of the scale drops slowly, but it is half as fast in the second half, then this phenomenon is relatively common.
Because under normal circumstances, when the fuel gauge of the vehicle goes down from high to low, if the first half can travel 300 kilometers, the second half can only drive about 100 kilometers. That is to say, in the first half of the year, the fuel gauge of many models will drop relatively slowly, and after passing the middle scale, it will drop relatively quickly. This is mainly related to the design of the oil pump used to reflect the amount of oil. It cannot reflect the change in gasoline consumption very uniformly. After all, this absolutely uniform change is difficult to achieve, and it is not easy to change by repairing and replacing parts.
