What does 'Check Engine System' mean?

Please check the engine system may indicate engine system failure, ESP failure, or sensor issues. It is recommended to visit a 4S shop as soon as possible to read the fault code, diagnose the cause of the fault, and carry out timely repairs to avoid affecting driving safety. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, and electric motors. The engine consists of three major parts and five service systems, namely the body assembly, crank-connecting rod mechanism, valve train; ignition system, starting system, lubrication system, cooling system, and fuel supply system.
When I saw the 'Check Engine System' warning pop up on the dashboard, my first thought was that the engine computer detected an abnormality. There are quite a few reasons why this warning light comes on. Last time I encountered it, it was because the fuel tank cap wasn't tightened properly, causing fuel vapor leakage - just tightening it solved the issue. It could also be a false alarm due to poor sensor contact or carbon buildup in the throttle body. Of course, more serious possibilities include oxygen sensor failure, ignition coil damage, or a clogged catalytic converter. My advice is not to panic immediately - first assess the car's condition: if acceleration feels normal without shaking or black smoke, you can drive to a repair shop for diagnosis; but if you notice power loss or unusual engine noises, pull over immediately and call for roadside assistance. I make it a habit to regularly replace air filters and spark plugs, which helps prevent many of these issues.
