What does the engine warn fault mean?

[ZoeyAnn]

Engine warn fault is the warning light for water in the fuel. The following are the effects of water in the fuel on the car: 1. Shaking: If there is water in the gasoline, the engine will experience abnormal shaking. Once water is mixed into the gasoline, it prevents the fuel and gas in the cylinder from fully mixing and burning. 2. Weak acceleration: If there is water in the gasoline, the car will have weak acceleration. Gasoline cars basically rely on burning gasoline to drive the engine to work. Fundamentally, it blocks the car's power system. 3. Difficulty starting: If there is water in the gasoline, the vehicle will become difficult to start. The spark plug will have difficulty igniting the fuel normally, which will make it difficult for the car to start, or even prevent the vehicle from starting at all.
