What does it mean when a faucet symbol appears on the car?

The appearance of a faucet symbol on a car indicates an engine fault. When this symbol appears, it means there is a problem with the car's engine. Here are some possible symptoms when the engine fault light is on: 1. The quality of the car's exhaust emissions deteriorates, polluting the environment; 2. Increased fuel consumption, wasting petroleum and financial resources; 3. Elevated combustion chamber temperature and increased wear, potentially leading to premature engine damage; 4. Engine oil burning; 5. Increased engine noise, affecting driving and passenger comfort. Additional information: Engine faults may cause unstable driving, frequent stalling, difficulty starting, reduced power, and abnormal vibrations. When the faucet symbol appears on the dashboard, it is recommended to immediately take the vehicle to a repair shop for professional inspection to avoid unnecessary issues.

Last time I was driving, I also encountered this 'faucet light' turning on and panicked, quickly pulling over to check the manual. It's actually the engine fault warning light, just designed with an icon resembling a faucet. In my case, it was caused by a loose fuel tank cap, but more common issues could be an oxygen sensor malfunction, aging spark plugs, or a clogged catalytic converter. I suggest trying to restart the vehicle first. If the light remains on, don't take it lightly. The most reliable approach is to find time to connect an OBD scanner to check the fault codes. Ignoring minor issues might lead to major problems. Once, a friend of mine overlooked this light and ended up with an engine overhaul, costing several thousand dollars.

I've been repairing cars for over a decade and see this check engine light every day. Beginners often mistake it for a coolant leak, but it's actually an engine management system warning. Common triggers include poor fuel quality, ignition system issues, or intake leaks. Don't panic when it lights up - if it doesn't disappear after restarting the engine, immediately read the trouble codes. Remember last time when Master Wang kept driving long distance with the light on, only to break down halfway. Replacing sensors is minor, but engine seizure would be disastrous. Regular air filter changes during maintenance are crucial, especially in areas with poor air quality where this warning gets triggered easily.

When I first bought the car, I was also startled by this 'water tap' warning light. The technician said it indicates the engine detected abnormal combustion, possibly related to recent fuel quality. In my case, the light came on because the fuel cap wasn't tightened properly - it went off after a few kilometers of driving once I resealed it. If the light stays on, immediately connect a Bluetooth OBD scanner to check the trouble codes (you can find them on Taobao for just tens of RMB). This is far better than guessing blindly - last month, my neighbor Old Li wasted 800 yuan replacing spark plugs unnecessarily when the actual problem was with the fuel pump.
