What does it mean when the car prompts to check the engine system?

When the car prompts to check the engine system, it indicates that there is an issue with the components of the vehicle's engine. The engine warning light illuminates to alert the owner to inspect the engine components. The engine emission system fault light, commonly referred to as the engine fault light, will turn on the indicator on the dashboard when the ECU detects and reads a fault code. Possible causes for the engine exhaust system malfunction include substandard gasoline quality leading to catalytic converter poisoning, or damage to the oxygen sensor in the catalytic system. This can result in reduced power during driving, increased fuel consumption, and more severe exhaust pollution from the vehicle.
My car also showed this yellow warning light a few days ago. After checking, it's an engine management system alert. The most common causes are dirty or faulty sensors like the oxygen sensor or mass air flow sensor, causing the ECU to receive inaccurate data. Using low-quality fuel can also trigger the light, as impurities may clog the fuel injectors. For older cars, check if the spark plugs are leaking electricity or if the catalytic converter in the exhaust system is blocked. Don't keep driving when this light comes on - if you notice reduced power and shaking, pull over immediately and call a tow truck. Last time I went to the repair shop, they scanned it with a diagnostic computer and found the issue in three minutes - just a loose connection on the intake pressure sensor. Small problems like this don't cost much to fix.
