Fuel gauge inaccuracies can be attributed to: 1. Poor contact or severe wear of the fuel level sensor's sliding resistor; 2. Abnormal instrument circuit or loose/aged electrical components; 3. Fuel tank deformation or bracket abnormalities; 4. Internal loose connections or open circuits in the engine control module; 5. Loose grounding wires of the vehicle's fuel level sensor or fuel pump wiring harness. The fuel gauge consists of a stabilized fuel level indicator and a fuel level sensor, designed to illuminate a warning when the fuel quantity falls below a specified threshold to alert the driver. It displays the remaining fuel quantity in the tank, which can be indicated either by a pointer or digital display.
