What is the reason for a faucet-like light on the dashboard?

[LeVivian]

The reasons for a faucet-like light on the dashboard are: 1. Faulty spark plugs, ignition coils, fuel pump, or clogged fuel lines in the engine; 2. Poor contact in sensors for water temperature, crankshaft position, air flow, intake temperature, or oxygen sensors; 3. Poor fuel quality causing engine wear and triggering the warning light; 4. Excessive carbon buildup altering the engine's design parameters. The faucet-like light is the engine warning light. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning it in a sealed cylinder, producing expanding gases that push the piston to perform work. Internal combustion engines typically convert chemical energy into mechanical energy.
