What does the faucet symbol on the car dashboard mean?
2 Answers
The faucet symbol on the car dashboard indicates an engine malfunction. The reasons for this warning light include: 1. Sensor issues: When the water temperature, crankshaft position, air flow, intake temperature, or oxygen sensors are damaged, have poor contact, or signal interruptions, the car's ECU cannot accurately obtain engine data. 2. Maintenance issues: Irregular maintenance and poor driving habits can increase the burden on the engine. 3. Fuel quality issues: The fuel added to the car has a specific grade, and failure to meet the required specifications can cause engine wear. 4. Poor combustion of the air-fuel mixture: This can lead to engine carbon buildup or knocking problems, which are detected by the engine's oxygen sensor. 5. False faults: These can occur due to impacts while driving, tampering with certain engine connectors, or temporary ECU signal interruptions.
I've been driving for over ten years, and when I see that wrench icon on the dashboard, I know it's the engine fault light. This thing usually appears when the car detects an issue with the emission system, such as a faulty oxygen sensor, incorrect fuel mixture ratio, or a malfunctioning catalytic converter. I remember last winter when this light suddenly came on in my car. First, I checked if the fuel cap was tight—it was loose. After tightening it, the light went off briefly but then came back on. I ended up driving to the repair shop, where they scanned the fault code and found severe carbon buildup on the exhaust pipe sensor. After cleaning it, everything was back to normal. New drivers shouldn't take this lightly—when the light is on, it means the engine isn't working properly. At best, it could lead to increased fuel consumption; at worst, you might end up stranded on the road. I recommend getting it diagnosed by a professional shop as soon as possible to avoid costly repairs down the line. Using high-quality fuel can also help prevent such issues.
