What Causes Inaccurate Fuel Gauge Readings in Cars?
1 Answers
The reasons for inaccurate fuel gauge readings in cars are as follows: 1. Fluctuating readings. This is a relatively common issue where the fuel gauge does not change at a consistent rate. For example, the first half of the fuel may last for 300 kilometers, while the second half only lasts for 100 kilometers. This occurs because the fuel pump, which measures the fuel level, cannot uniformly reflect the changes in gasoline consumption. 2. Sudden drop to zero. The fuel gauge readings are transmitted via a sensor that monitors the fuel level. If the gauge suddenly drops to zero despite having a significant amount of fuel remaining, it is likely that the vehicle's fuel level sensor is malfunctioning, possibly due to damage or being covered by dirt. 3. Unusual rise in fuel gauge readings. Sometimes the fuel gauge may appear stuck at a certain position or show an unusual increase in readings after driving a certain distance. This is mainly caused by the linkage between the fuel level sensor and the float getting stuck, preventing the float from moving up and down properly, thus keeping the sensor from updating. 4. To minimize these issues, it is advisable to use higher-quality fuel and avoid refueling at unregulated gas stations, as the impurity content in gasoline can directly affect the lifespan and performance of the fuel level sensor.
