What does the faucet symbol on the car dashboard mean?

[VonMariana]

The faucet symbol on the car dashboard indicates an engine malfunction. The reasons for its illumination are: 1. Fuel quality issues: The fuel added to the car has a specific grade, and failure to add it as required can cause engine wear; 2. 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; 3. False faults: Occur due to impacts while driving, tampering with certain engine connectors, or temporary signal interruptions in the ECU; 4. Sensor problems: When the water temperature, crankshaft position, air flow, intake temperature, or oxygen sensors are damaged, have poor contact, or experience signal interruptions, the car's ECU cannot accurately obtain engine data; 5. Maintenance issues: Failure to perform regular maintenance and poor driving habits can increase the burden on the engine operation.
