fuel level sensor float
The fuel level sensor float itself is a sliding rheostat. The output resistance of the float increases according to the decrease of the oil level in the mailbox. In this way, the output voltage will decrease accordingly, and the instrument indication will decrease.
There may be impurities in the gasoline. Generally, the automobile fuel level sensor float and the sensor are connected together. However, soaking in the gasoline for a long time will cause the oil fuel level sensor float to be worn to varying degrees, resulting in inaccurate oil volume display. Therefore, I personally recommend that the oil fuel level sensor float be changed regularly to ensure that the oil volume display is normal, so as to avoid being unable to judge the specific oil volume due to inaccurate oil volume display, Thus, the fire cannot be ignited due to lack of oil during driving.
The oil gauge does not display the oil level or the display is inaccurate, so we cannot correctly know the amount of gasoline in the tank. In addition to this method, we can also observe the oil gauge while driving. If we can't drive normally at this time, it means that the fuel level sensor float is broken.
The automobile fuel level sensor float is also called the fuel tank float. The fuel tank float is not only a fuel buoy, but also a fuel level sensor. This device, together with the fuel gauge, constitutes an automobile fuel level detection system. So this thing is also connected with the gasoline pump. It is completely floating on the oil surface by buoyancy, that is, the position of the oil float, that is, the position of the oil surface. Therefore, we can know the oil storage capacity of the oil tank by observing it.
We understand how the oil gauge displays the oil quantity. It is connected to a metal rod through a floating ball in the oil tank. This principle is similar to the toilet water tank in the toilet. If it is some old cars, it may be the problem of the fuel level sensor float, which is what we call the oil level sensor. Then we can check whether the plug of the oil level sensor on the oil tank is loose and whether it is oxidized and ablated; Observe whether the oil level sensor is stuck during the sliding process.
