sight gauge fuel level can't see
When the fuel level of the fuel gauge in the fuel tank is less than the specified value, the alarm light will light up, which needs to be paid attention to by the car owner. However, the fuel gauge does not display the fuel level, mainly because the fuel tank float is not only a fuel float, but also a fuel level sensor device. Therefore, if it fails, it will cause the fuel gauge to not display the fuel level; If there is a problem with the vehicle computer signal, it will affect the display of the fuel gauge; In addition, the damage of the oil gauge itself is also one of the reasons. If the vehicle can be started at this time, the needle of the oil gauge will not swing randomly in a short period of time, and the measurement verification is inaccurate, it can be determined that it is a common fault of the oil gauge. If it is in other states, a multimeter needs to be used for measurement and maintenance; Another final situation is that the fuel tank is too low, and the car mainly needs to refuel in a timely manner.
The reasons why the Fuel gauge does not display the fuel quantity are: 1. The oil slick and ignition wire are abnormal: the abnormal display of the automobile fuel gauge is generally caused by the failure of the oil pointer (oil level display sensor), and the fuel gauge detects the oil level by the oil pointer. If the detection signal is distorted, this problem will occur. First, check whether the hot line and the oil floating line are normal. If not, check the wiring. If normal, remove the oil float and move it up and down by hand. If it moves, the oil float will be damaged. Solution: The floating oil needs to be replaced. 2. Computer signal failure: Some oil level displays are controlled by computers, and inaccurate display may occur when the computer signal fails, which is a low probability. Solution: Switch the key again. If the switch fails, the floating oil can be replaced. Suggest going to a 4S repair shop to repair the on-board computer. 3. Instrument damage: The method of not displaying fuel quantity on the car fuel gauge is as follows: 1. Lock the car after closing the key door; 2. After waiting for ten minutes, unscrew the key door and check if the oil level is displayed; If there is no display, replace the floating oil, computer signal, and instrument.
How to solve the problem of abnormal display on the car oil gauge? When the oil gauge itself is damaged, it is necessary to replace it with a new one in a timely manner. When there is a problem with the circuit, it is necessary to check the oil level sensor and oil float in the fuel tank. We also need to consider whether there is deformation between the float rod and the fuel tank. If there is deformation, it will make the fuel float unable to accurately reflect the liquid level, and it needs to be replaced in a timely manner. Once the resistance values of the oil level sensor and instrument do not match properly, the difficulty of maintenance will increase, and it is necessary to go to a professional organization for maintenance.
