What does it mean when the faucet indicator light comes on?

[DeRiley]

When the faucet indicator light comes on, it indicates the engine malfunction indicator light is illuminated. This could be caused by poor engine combustion conditions, engine knocking, low-quality fuel, dirty engine cylinders with carbon deposits, or the computer failing to retrieve engine data. An engine is a machine that converts other forms of energy into mechanical energy. The first external combustion engine was invented by R. Stirling in the UK (Scotland), later improved by Watt into the steam engine. Engines can refer to either power generation devices or entire machines including power units (such as gasoline engines, aircraft engines). Types include internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), gas turbines (racing cars), and electric motors.
