Is Your Fuel Gauge Telling the Truth?

Don't be fooled again, the three major reasons for the misleading of the fuel gauge!

Cars and bullets must be a headache for car owners. When you have a car in an emergency, it is inevitable that people will be mad at the "deception" of the fuel gauge! The main cause of fuel gauge failure is the fuel level sensor. Usually, the fuel gauge scale is inaccurate and there are several situations...

"The main cause of fuel gauge failure is the fuel level sensor. "

Symptom 1: The meter scale is fast and slow Specific realization: the fuel gauge scale display is fast and slow.

Analysis: This phenomenon of fuel gauge failure is more common. Under normal circumstances, the oil gauges of many models will fall more slowly in the first half, and will fall faster after passing the middle scale. This is mainly related to the design of the oil pump used to reflect the amount of oil. It does not reflect the change in gasoline consumption evenly. After all, this absolute uniform change is difficult to achieve and it is not easy to change by repairing replacement parts

Symptom 2: The scale of the fuel gauge suddenly drops to zero Specific performance: I saw two squares in the middle of the road, but after driving a certain distance, I even dropped directly to zero.

Analysis: The indication of the oil gauge depends almost entirely on the fuel level sensor, so the oil gauge pointer is actually an intuitive representation of the fuel level sensor. When this problem occurs, it indicates that there is a problem with the vehicle's fuel level sensor. Generally, due to the stain on the fuel level sensor, it needs to be cleaned in time. Because the gasoline contains a lot of impurities, and the fuel level sensor is always immersed inside, it will be polluted for a long time, which directly affects the accuracy of the indication. If the vehicle has been in use for more than 5 years, if the indication of the fuel gauge is inaccurate, it is likely that the fuel level sensor has been physically worn out and cannot continue to work normally.

Symptom 3: fuel gauge scale rises The specific performance: the pointer of the fuel gauge has remained at a certain position for a long time, and some even show a numerical value after a certain distance.

Analysis: The main reason for this situation is that the connecting rod between the fuel level sensor and the float is stuck, so that the float can not float up and down normally, so that the sensor does not change, so the oil gauge pointer is fixed in one position.

How to let the fuel gauge tell the truth?

First, try to choose a better gasoline. Clean gasoline will cause less impurities in the oil pump, greatly reducing the probability of fuel gauge failure.

Secondly, regularly clean the oil circuit and fuel tank Every time the vehicle travels about 5,000km, the oil circuit cleaner is used to clean the oil circuit of the car, and the fuel tank is cleaned every two years. Due to long-term use, a thick layer of sludge will appear at the bottom of the tank, which will indirectly affect the accuracy of the oil gauge.
