What does the faucet symbol on the dashboard mean?

[DiBrandon]

The appearance of the faucet symbol on the dashboard indicates that the engine exhaust emission fault light is illuminated. Here are specific details about the faucet symbol: 1. This indicator light is used to display the working condition of the vehicle's engine. When the ignition is turned on, the light will illuminate during the vehicle's self-check and then automatically turn off. If it remains lit, it indicates a mechanical fault in the engine that requires repair. 2. The engine exhaust emission warning light functions by monitoring the engine's air-fuel mixture state through the oxygen sensor. If the mixture changes and causes the exhaust emissions to exceed standards, the control unit will record the fault and illuminate this warning light to alert the driver. The driver can continue driving, but fuel consumption may increase, and driving comfort may deteriorate. It is recommended to visit a repair station for inspection and repair as soon as possible. 3. Common causes include: a dirty throttle body (recommended cleaning every 20,000 to 30,000 kilometers) and excessive carbon buildup on the valves and fuel injectors (recommended cleaning of the intake and fuel systems every 30,000 to 40,000 kilometers).
