What are the reasons for inaccurate car fuel gauge readings?
1 Answers
The reasons for inaccurate car fuel gauge readings: 1. The fuel gauge pointer fluctuates irregularly: This cannot necessarily be considered a malfunction, as it is related to the design of the fuel pump used to reflect the fuel level; 2. The fuel gauge scale rises: This occurs because the linkage between the fuel level sensor and the float gets stuck, preventing the float from moving up and down normally, causing the fuel level sensor to remain unchanged, thus the fuel gauge pointer stays fixed at a certain position; 3. The fuel gauge suddenly drops to zero: When this happens, it indicates an issue with the vehicle's fuel level sensor, most likely due to contamination of the sensor that hasn't been cleaned in time. Gasoline contains many impurities, and the fuel level sensor being constantly immersed in them can become polluted over time, directly affecting the accuracy of the readings.
