fuel level sensor high
The oil gauge displays high and low, which is mainly caused by the oil level sensor. If it is a new car, it is common for it to go up and down. It is recommended to choose gasoline with better oil as much as possible when refueling your car, because clean gasoline will reduce the impurities in the oil pump and reduce the probability of oil gauge failure. When the new car is in the running in period, the oil gauge will be high and low. This phenomenon is very normal. However, when the old car encounters such a situation, it should be checked carefully.
The automobile oil gauge is used to indicate how much oil is available in the fuel tank of the automobile. It is composed of a fuel level indicator with a regulator and a height sensor for sensing the oil level. When the fuel is lower than a certain limit value, the display screen will light up and give an alarm to remind the driver. However, some people may find that the fuel gauge is sometimes not so accurate.
This situation is often encountered. The number of oil representatives does not change at a uniform speed. For example, the first half of the oil can travel 300 kilometers, while the second half can only travel 100 kilometers. This key is related to the design of the oil pump used to reflect the oil quantity. It can not reflect the change of gasoline consumption evenly. After all, such absolute uniform change is very difficult to achieve.
When it suddenly drops to zero, the indication of the fuel gauge reflects the fuel level through the sensor. If there is still a lot of oil and the indication suddenly drops to zero, it is very likely that there is a problem with the fuel level sensor of the vehicle. Since the fuel consumption needs a process, the half tank of oil will not disappear suddenly. The sensor may be damaged or covered with dirt.
The scale of the oil gauge rises. Sometimes it seems that the scale of the oil gauge does not work, stays at a position, or the reading rises abnormally after driving for a certain distance. The key reason for this situation is that the connecting rod between the oil level sensor and the float is stuck, so that the float can not float left and right normally, and the sensor will not change.
