Why does refueling without turning off the engine cause the fuel gauge to be inaccurate?
1 Answers
Due to the presence of many impurities in gasoline, the fuel level sensor, which is constantly immersed in it, can become contaminated over time, directly affecting the accuracy of the readings. The following are reasons for inaccurate fuel gauge readings: 1. Fuel level sensor issues: The fuel level sensor may have poor reliability or be damaged. 2. Problems with the fuel gauge: If the fuel gauge needle drops at inconsistent rates, it could be a design issue. Some vehicle models' fuel gauges are not designed linearly, with the first half being slower and the second half faster, which is relatively normal. An unstable fuel gauge needle may indicate an issue with the fuel level sensor. If the fuel gauge needle does not reach the top after confirming a full tank, there may be a problem with the fuel gauge display.
