What Causes the Fuel Gauge to Stop Moving?
1 Answers
The fuel gauge needle not moving is usually caused by a damaged fuel level sensor (commonly known as the fuel float). It is recommended to go to a repair shop and connect the two wires of the fuel float. If the fuel gauge needle goes to the top, it indicates the fuel float is damaged. If it still doesn’t move, check the wiring and the dashboard. If the needle doesn’t move immediately after filling up the tank, it means the fuel float is completely pushed to the top of the tank by the buoyancy of the fuel, and the needle connected to the sensor cannot rotate. Only after consuming some fuel and the float descending will the needle move with the sensor. Steps to Diagnose a Non-Moving Fuel Gauge: First, check whether the battery has power. If the gear display and headlights are working normally, there is no issue with the battery. If there is power, check the fuel level sensor (fuel float). Use a wire to short-circuit the two wires of the float. If the fuel gauge responds, the issue is with the float. The fuel float has a small chip sensor at the top, which may get dirty due to poor fuel quality, affecting the contact points. Clean it with an eraser. After removing the dashboard, use a multimeter and a needle to locate and check the wiring corresponding to the fuel gauge.
