What does the faucet symbol on the car dashboard indicate?
2 Answers
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.
