how to check fuel level without gauge
The main reason for the inaccuracy of automobile fuel level gauge is the fault of fuel level sensor. Usually, the inaccurate scale of the oil gauge will lead to the speed of scale display, resulting in the driver's inability to correctly observe the scale of the automobile oil gauge, which needs to be maintained in time. The car's fuel gauge is under the instrument panel. When there is no oil, return to the red area on the left side of the fan. Make sure the vehicle is full of fuel. If the fuel gauge is still inaccurate, you can go to the repair shop for debugging. Sensors and equipment are also the reasons for the inaccuracy of the oil gauge. Equipment failure will also cause the oil gauge pointer to fail to achieve accurate reading, which can only be handled by the professional commissioning equipment of the repair shop. If it shows a problem, please clean and wipe the oil gauge, or carry out maintenance through a professional repair shop.
Regularly check the automobile fuel level and purchase professional cleaning tools for treatment. Cleaners need professional knowledge. Professional cleaning, you can find a car beauty shop for corresponding cleaning. Many car owners have encountered this situation. When it is clear that the oil has just been filled up, the oil gauge shows that the oil is insufficient, or it is clear that the oil gauge shows that there is more than half of the oil. As a result, there was no oil damage before driving far; In fact, this is due to the inaccurate fuel gauge, which may cause potential safety hazards. The automobile fuel gauge consists of a measuring unit and a display unit. The measuring unit is responsible for measuring how much oil is left in the mailbox, and then sending a signal to the display unit, which then displays how much fuel level is left in the mailbox. The measuring system consists of float, metal rod and variable resistance in oil tank. The position of the float on the oil level of the oil tank changes. The oil volume can be measured through the position change of the metal rod and then the position change of the variable resistance.
The scale of the fuel level gauge suddenly drops to zero: the pointer of the oil gauge almost depends on the oil level sensor, so the pointer of the fuel level gauge is the visual expression of the oil level sensor. If this happens, it means that there is a problem with the vehicle's oil level sensor. In this case, it may be necessary to clean the oil level sensor in time. If the vehicle has been used for more than 5 years, the oil level sensor may be physically worn and cannot continue to work normally. The scale of the oil gauge rises: this situation is mainly manifested in that the pointer of the fuel level gauge stays at a certain position all the time, and even after driving a certain distance, the scale display system actually rises. The main reason for this is that the connecting rod between the oil level sensor and the float is stuck, so that the float cannot float up and down normally, resulting in the sensor unchanged and the pointer of the oil gauge frozen at a certain position.
