How to Fix Inaccurate Fuel Gauge on Wuling Zhiguang?
2 Answers
Check the wiring from the fuel level sensor to the ECU. If there are open circuits or poor connections, the wiring needs to be repaired. Inspect the fuel level sensor for poor contact or severe wear on the sliding resistor. Replacing the fuel level sensor can resolve the issue. Abnormalities in the instrument circuit or aging electrical components with poor connections can also cause inaccurate fuel gauge readings. Replacing the instrument cluster can fix the problem. If the fuel gauge inaccuracy is due to tank deformation or abnormal mounting brackets, these faults can only be checked by removing the fuel pump. If there are poor connections, open circuits, or short circuits inside the engine control module, a diagnostic tool can be used to help identify the issue.
My Wuling Zhiguang's fuel gauge has been inaccurate several times, which is really troublesome. The most common reason is a faulty float sensor in the fuel tank – when the float can't properly float in the fuel, the readings go haywire. Sometimes it just gets stuck by oil residue and cleaning helps; if completely broken, you'll need to replace it. Here's how to check yourself: Park on level ground, open the trunk and lift the mat to access the fuel tank opening, then carefully remove the sensor to check if the float moves freely. If stuck or broken, buy a compatible Wuling replacement part online – they're cheap, just tens of RMB. Remember to disconnect the battery first to prevent short circuits. After replacement, the gauge will work accurately, giving peace of mind on long trips. Monitor gauge behavior during regular refueling to catch issues early. If the sensor is fine, it might be loose wiring or a blown fuse, but always start with this check first.
