What does it mean when a car displays a faucet symbol?

When a car displays a faucet symbol, it refers to the engine status indicator light. This warning light indicates the operating condition of the vehicle's engine. During vehicle startup when the system performs self-check, this light will illuminate briefly and then turn off automatically. If the light remains illuminated, it signifies potential issues such as poor engine combustion condition, engine knocking, inferior fuel quality, or internal cylinder contamination. The engine malfunction light is controlled by the engine control unit (ECU), which essentially monitors all electronic components of the engine. Therefore, any malfunction will be displayed through this warning light. There are numerous reasons for engine warning light illumination, including but not limited to: mass airflow sensor failure, ignition coil malfunction, thermostat issues, catalytic converter problems, oxygen sensor defects, or excessive carbon buildup in the electronic throttle body.
I also encountered that faucet-like light coming on while driving the other day, which really startled me. Later I learned it's the engine malfunction indicator lamp, warning of engine issues with many possible causes like sensor failure, exhaust system leaks, or fuel supply problems. If it stays steadily lit and the car still runs, it's usually a minor issue but shouldn't be ignored - untreated, fuel consumption may increase or even cause engine failure. I recommend getting an OBD scanner to plug into the diagnostic port, read the trouble codes to identify the specific issue, then have it fixed at a repair shop. Safety first - driving with this light on is no joke.
