What's the matter with the fault code indicating excessively high fuel concentration?

[ONicole]

Fault codes are related to the gasoline being used. If the detonation value fails to meet the standard, it indicates a long-term issue with poor fuel quality causing the fault code. It may also result from vacuum leaks in the engine intake system, excessive carbon buildup, or contaminated fuel injectors. Additional information: 1. Types of fuel gauges: The fuel gauge on the dashboard typically comes in analog or digital forms, marked with 'F' and 'E' at each end. 'F' indicates a full tank, 'E' means the fuel is empty, and the middle position shows half a tank. When the fuel warning light comes on, it means the gauge is approaching 'E'. 2. Running out of fuel: Generally, when the fuel gauge pointer reaches the red line, there is about 10% fuel left in the tank, allowing an average driving range of 20-60 km, depending on the vehicle model. If you continue driving without refueling beyond the red line, it may cause the fuel pump to burn out.
