What does the faucet symbol on the car dashboard indicate?

The faucet symbol that appears on the car dashboard is the engine malfunction indicator light. During driving, if this light stays on continuously, it may indicate the following potential issues: poor engine combustion state, engine knocking, poor fuel quality, dirty engine cylinders, accumulated carbon deposits in the engine, or the computer failing to retrieve engine data. The engine malfunction light is triggered by the ECU (Engine Control Unit), commonly referred to as the car's computer. The ECU controls all electronic components of the engine, including the electronic throttle, fuel injectors, alternator, fuel injection pump, catalytic converter, and covers systems such as intake, exhaust, fuel delivery, ignition, and timing. When the engine malfunction light remains illuminated, it is necessary to stop the vehicle and call for professional assistance to resolve the issue.
I've encountered that faucet-shaped symbol several times - it's actually the check engine light, indicating the onboard computer has detected an issue in the engine system. Common problems include faulty oxygen sensors or catalytic converters, ignition coil malfunctions, or exhaust system abnormalities. Last time my light came on, diagnostics showed a clogged fuel injector which was fixed to clear it. Don't underestimate it - ignoring this can damage the engine, increase fuel consumption and safety risks. If illuminated, I recommend immediately checking the dashboard for other warnings, then promptly visiting an auto shop for OBD-II scanner diagnostics (usually costs around tens of RMB). Regular maintenance like oil changes and component cleaning helps prevent such issues. In short, taking this indicator seriously extends your car's lifespan and ensures safer driving.
When the water tap symbol lights up while driving, I always feel the need to be cautious—it's the engine fault light, warning of an issue with the engine control system. Possible causes include a damaged sensor, clogged fuel line, or excessive emissions. I've encountered a similar situation before, which turned out to be a faulty air flow meter. Once this light comes on, it's crucial to monitor other dashboard signals to prevent overheating or brake problems. Safety first—I immediately slow down and pull over, avoiding the risk of pushing through to the destination, which could lead to major engine repairs or accidents. Remember, simple checks like tightening caps or inspecting connectors might help, but it's best to have a professional shop diagnose the issue. Regular maintenance, such as replacing filters and using quality fuel, can also prevent frequent light activations. Developing good habits ensures your car remains reliable.
As a new driver, I was startled the first time I saw the faucet symbol, only to later learn it was the engine malfunction indicator light. When illuminated, it signals an engine abnormality, such as an oxygen sensor issue or insufficient oil pressure. Simply put, the onboard computer is sounding an alarm—it might be a minor issue, but it shouldn't be ignored. I've found the handling procedure quite straightforward: if the light flashes, pull over immediately for inspection; if it stays on steadily, head to an auto repair shop to scan for trouble codes. I make it a habit to regularly monitor dashboard indicators and maintain good vehicle condition to prevent unexpected headaches. With more driving experience, I've come to appreciate the importance of promptly heeding these small warning signals for smoother journeys.
