What does the faucet-like symbol on the car mean?

[LaKiara]

The faucet symbol appearing on a car indicates an engine malfunction. There are numerous reasons why the engine warning light may illuminate, with the following being the most common: 1. The oxygen sensor connector is damaged or loose, causing the air-fuel mixture to be too lean or too rich. 2. Poor-quality or substandard gasoline leads to incomplete combustion of the air-fuel mixture during engine operation. 3. Inadequate engine maintenance, such as issues with spark plugs, ignition coils, fuel pumps, or clogged fuel lines, results in poor combustion of the engine's air-fuel mixture. 4. Engine combustion requires proper air intake. A dirty or uncleaned air filter can obstruct airflow over time, severely affecting the engine's air intake and potentially triggering the engine warning light.
