What does the fuel tank symbol on the dashboard mean?
1 Answers
The appearance of a fuel tank warning light on the dashboard can indicate one of two situations. The first is that the fuel level is critically low, requiring immediate refueling at a gas station. From the warning alert until the fuel is completely depleted, most vehicles can still travel approximately 30-50 kilometers. The second situation involves a malfunctioning fuel tank sensor, commonly caused by issues such as air leakage in the fuel tank's float. Below are more detailed explanations: 1. Abnormal fuel tank warning: The fuel warning light does not only activate when the tank is completely empty; it may display in advance when the fuel level is nearing empty to alert the driver. Some vehicle dashboards may also show the estimated remaining driving distance. If the fuel tank symbol persists after refueling, other potential faults should be considered. 2. Aging fuel tank float: The float inside the fuel tank is typically made of foam plastic material, designed with a hollow structure to allow it to float on the fuel surface. Over time, the float may age, leading to air leakage and fuel seepage. In such cases, the float may become too heavy to properly float and guide the variable resistor. This issue can be resolved by replacing the float at a repair shop. 3. Additional functions of the fuel tank symbol: Some vehicle dashboards feature a fuel tank symbol with a left or right arrow, indicating the side of the vehicle where the fuel tank is located. This helps drivers avoid the inconvenience of repositioning their vehicle at gas stations, especially when the fuel tank and pump are on opposite sides due to crowded conditions or varying station layouts.
