If your gas gauge reads full all the time, it could be due to a faulty fuel level sensor, which may be stuck or malfunctioning. Another possibility is a wiring issue, such as a short circuit, that is sending a constant signal to the gauge. Additionally, problems with the instrument cluster itself can also cause incorrect readings. It's best to have a mechanic diagnose the issue to determine the exact cause.
