What are the reasons for the inaccurate fuel gauge display on the Baojun 510?

The reasons for the inaccurate fuel gauge display on the Baojun 510 include: faulty fuel level sensor, clogged carbon canister, malfunctioning fuel gauge, etc. Fuel refill amount: Generally, filling until the pump automatically stops is sufficient. There is no need to manually add more to round up the amount. After refueling, remember to tighten the fuel cap until you hear a click before leaving. Checking the fuel gauge: Before driving, check the fuel gauge. Based on the distance of your trip and the fuel gauge reading, calculate whether you need to refuel during the journey. It is advisable to refuel in advance rather than waiting for the fuel warning light to come on. The fuel pump is located inside the fuel tank and operates at high temperatures when continuously working. Being submerged in fuel helps to cool it effectively. When the fuel warning light comes on, it indicates that the fuel level is below the fuel pump. If you always wait for the light to come on before refueling, it will shorten the lifespan of the fuel pump. Additionally, having too little fuel in the tank may even cause the fuel pump to burn out. Best time to refuel: It is better to refuel in the morning or evening, avoiding the midday when the sun is strong and temperatures are high. Gasoline is charged by volume rather than by weight, and it expands with heat and contracts with cold. Refueling in the morning or evening means that the same volume of gasoline will have a higher mass, saving you money.

I also encountered inaccurate fuel gauge readings when driving the Baojun 510. The main cause is usually a problem with the fuel level sensor, such as the float in the fuel tank getting stuck due to sludge or debris, preventing accurate position detection. It could also be due to aging or loose wiring, causing signal transmission issues to the dashboard. I've experienced situations where the tank was full but only showed half, especially more common in cold weather when the float tends to stick to the bottom of the tank. Dashboard malfunctions are rare, but the display module can sometimes glitch. I recommend filling up the tank to test the gauge's response—if it's stuck, try gently rocking the car to dislodge it. If that doesn't work, head to a repair shop immediately. Regular maintenance and cleaning of the fuel tank can prevent such issues—don't wait until you're stranded on the road to address them. Accurate fuel level readings are crucial for safe driving, so don't overlook these small details.

Regarding the inaccurate fuel gauge of the Baojun 510, the first suspicion falls on the fuel level sensor: the float assembly may be worn or stuck, and the tank design is prone to dirt accumulation affecting readings. There's also the issue of poor circuit connections, where oxidation at wiring harness contact points causes signal interruptions. Occasionally, a faulty instrument cluster display unit can also show incorrect readings. I recommend a simple diagnostic method: fill the tank and observe the fuel gauge's movement; if it remains static, it's likely a stuck sensor. Having a shop test resistance values and circuit voltage can confirm the issue. For repairs, cleaning or replacing the sensor is not costly, but safety is paramount. Regularly inspect wiring connections and the fuel pump's surrounding environment to extend component lifespan.

When I use this car, the fuel gauge keeps jumping around. It might be that the float is stuck due to oil contamination and can't move. There could also be a minor fault in the instrument display unit, causing inaccurate data. Loose connection points in the wiring can also cause issues. A simple solution: fill up the tank and observe the needle's response. If it doesn't match the actual fuel level, take it to a repair shop for diagnosis. Don't try to dismantle it yourself; let professionals test it safely. Remember this: misjudging the fuel level is very dangerous.
