What is the reason why the fuel gauge of Chery A3 keeps lighting up?
2 Answers
There may be several reasons: Fuel gauge elasticity in the fuel tank: If there is no elasticity in the fuel gauge inside the fuel tank, go to a 4S shop to replace it. Wiring issue: If there is a wiring problem, have it checked at a repair shop. Instrument panel issue: The indicator gauge is faulty. Low fuel level: There is a fuel level sensor on the fuel pump. When the fuel level drops below the set standard, the fuel gauge light will illuminate to remind the driver to refuel in time. Generally, after the light comes on, the car can still continue to drive 30-50 kilometers without any problem. Except for individual quality issues, the lifespan of the fuel pump is generally very long. Some cars never need to replace the fuel pump until they are scrapped. Of course, some may need to replace it after five or six years. The reasons for damage are usually due to aging, reaching the end of its lifespan, or excessive impurities in the fuel clogging the filter.
There could be several common reasons why the fuel gauge light stays on. I've seen many similar cases. If the fuel gauge light keeps illuminating while driving, it's mostly due to a faulty fuel level sensor—perhaps the float is stuck in the fuel tank, causing it to incorrectly report low fuel levels. It could also be an electrical issue, such as aging wiring or poor contact, where unstable current keeps the light on. If you've recently washed the car or driven through waterlogged areas, moisture in the connectors might cause a short circuit. A simple check is recommended first: fill up the tank to see if the light turns off, or start the engine to listen for unusual noises from the fuel pump. If the light remains on, it's best to visit a professional repair shop to test the wiring with a multimeter. After all, an inaccurate fuel gauge while driving is a serious issue—running out of fuel unexpectedly can be dangerous.
