What is the reason for the water tap light on the car dashboard?

[MasonAnn]

The reasons for the water tap light on the car dashboard are: 1. Poor gasoline quality leading to incomplete combustion of the air-fuel mixture in the cylinder, resulting in carbon deposits; 2. Excessive engine mileage causing weakened spark plug performance; 3. Vehicle mechanical aging or damage; 4. Sensor or computer board malfunction. The water tap symbol is the engine fault light. Hazards of the engine fault light turning on: 1. Degraded exhaust gas quality, polluting the environment; 2. Increased combustion chamber temperature and accelerated wear, leading to engine damage; 3. Causing the engine to burn oil; 4. Increased engine noise, affecting driving and passenger comfort. The function of the engine: To convert the thermal energy of gasoline into mechanical energy by expanding gases after combustion in a sealed cylinder, thereby driving the piston to perform work.
