Electrical issues: Electrical problems, such as a short circuit or loose connection in the wiring, may also cause the fuel gauge to malfunction and remain stuck at full.
Faulty instrument cluster: In rare cases, the problem could be with the instrument cluster itself, where the fuel gauge display might be receiving incorrect or faulty signals from the fuel gauge sensor.
To diagnose and fix the issue, it's recommended to have the vehicle inspected by a qualified automotive mechanic or technician who can accurately identify the root cause of the fuel gauge malfunction and perform the necessary repairs.
