What is the reason for the inaccurate fuel gauge display in Nissan Tiida?

The reason for the inaccurate fuel gauge display in Nissan Tiida is: the fuel level sensor is inaccurate, and replacing the fuel level sensor can solve the problem. Amount of fuel to add: Generally, filling until the pump automatically stops is sufficient. There is no need to round up to a whole number and manually add more. After refueling, remember to tighten the fuel tank 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 a high temperature 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 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. Since gasoline is charged by volume rather than weight, it expands when hot and contracts when cold. Refueling in the morning or evening allows the same volume of gasoline to have a higher mass, saving you money.
Last time I was driving my old Tiida, I encountered a situation where the fuel gauge was acting erratically—it showed half full after a full tank, and the needle didn’t budge even after driving over a hundred kilometers. Later, I figured out it might be the fuel tank float getting stuck, like a bath toy wedged in the corner of a tub. Frequently filling only half the tank or driving on bumpy roads can cause the float arm to deform and jam. Another time, after washing the car, I noticed the dashboard had water ingress, and the needle started flickering wildly. Corroded wiring connectors can also cause issues, especially noticeable after rain. My suggestion is to first disconnect the negative terminal of the battery for five minutes to reset the car’s computer. If that doesn’t work, you’ll have to dismantle the fuel tank for inspection.
