How to Repair a Faulty Fuel Tank Sensor?
1 Answers
Fuel tank sensor failure requires replacement of a new unit. A malfunctioning fuel level sensor can cause the car's fuel gauge to fail, with specific manifestations including: 1. Erratic fuel gauge needle movement; 2. Sudden drop of fuel gauge reading to zero; 3. Abnormal rise in fuel gauge reading; 4. The fuel level sensor operates by detecting changes in capacitance between the sensor housing and sensing electrode when fuel enters the container, converting this variation into current changes to determine fuel position. Capacitive fuel tank sensors are specialized instruments designed for precise fuel level measurement in railway locomotives, automotive fuel tanks, tank trucks, and oil depots.
