What does the engine indicator light on the dashboard mean?

Poor engine combustion status is the main reason for the engine fault light to illuminate. Here is some relevant information about engines: 1. Classification: Based on different power sources, automotive engines can be categorized into diesel engines, gasoline engines, electric vehicles, and hybrid vehicles. Conventional gasoline and diesel engines are reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy to move the pistons and output power externally. 2. Performance: Gasoline engines have high rotational speeds, low weight, low noise, easy starting, and low manufacturing costs; diesel engines have higher compression ratios, greater thermal efficiency, and better economic and emission performance compared to gasoline engines.
The engine warning light on the dashboard is no small matter. I've encountered it several times while driving, and it usually indicates an issue with the engine management system that needs immediate attention. Common causes include aging oxygen sensors sending incorrect signals, clogged catalytic converters leading to excessive emissions, unstable oil pressure in the fuel system, or loose sensor wiring harnesses. Don't underestimate this small light—it can signal serious underlying problems, such as potential engine damage or increased exhaust pollution if left unresolved. I recommend pulling over safely to check if the fuel cap is tightened. If you can't fix it yourself, take the car to a repair shop to scan for trouble codes with specialized diagnostic equipment. Don't delay—procrastination can lead to higher repair costs and more severe damage. Regular vehicle maintenance can help prevent such issues.
