If your fuel gauge is inaccurate, the problem lies with:
* The fuel level sensor: This is the most likely culprit. It's a float inside the fuel tank that sends a signal to the gauge. It can become damaged, stuck, or inaccurate over time.
* The gauge itself: The gauge in the instrument cluster could be faulty.
* Wiring issues: Problems with the wiring between the sensor and the gauge can also cause inaccurate readings.
To fix an inaccurate fuel gauge, you'll need to have a mechanic diagnose the problem. They'll likely test the fuel level sensor and the wiring before replacing the gauge as a last resort.
