Why is the engine warning light of the VOGE 300AC constantly on?

There are three reasons for the engine warning light to be on: poor combustion state; engine knocking; internal factors causing the engine warning light to illuminate. The solutions for the engine warning light being on are as follows: Clear the fault code: If a fault code is reported but the engine operates normally, it may be due to an operation that exceeded the computer's control range, resulting in a fault code feedback from the computer. The fault code can be cleared first, and then observe whether the fault code reappears. Resolve the issue: If the engine does not show any particularly obvious faults, but further inspection based on computer detection information reveals the presence of a certain fault that does not affect normal driving or has minimal impact, it should be identified and resolved promptly. For example, a faulty intake pressure sensor, etc.
The engine warning light in my car had been staying on before, which really made me uneasy. At the time, I first pulled over to check the oil dipstick to see if the oil was low or dirty, and it turned out fine. Then I thought it might be a small sensor failure, like the oxygen sensor which often malfunctions because it's exposed to high temperatures for long periods. I also noticed that if the spark plugs were burnt out, it could trigger the light due to ignition failure. Sometimes even a clogged exhaust system can cause the computer to falsely report a fault. I immediately drove to the repair shop, and the mechanic scanned it and found the trouble code right away. Replacing the sensor fixed the problem. The whole process was quite simple, but if left unattended for too long, it could lead to a spike in fuel consumption or engine damage. So don’t be lazy—act early to avoid costly repairs for bigger issues. Also, remember to change the air filter regularly; keeping the system clean can help avoid such headaches.
I have quite some research on the persistent engine warning light. Possible causes include ignition system issues, such as aging spark plugs or damaged coils leading to misfiring; sensor malfunctions, like faulty coolant temperature sensors or mass airflow sensors; oil pressure problems where clogged oil pumps or filters trigger the system alarm; exhaust system faults where a blocked catalytic converter affects emission standards; or electrical circuit/control module errors causing false alarms. I suggest first checking basic oil levels and intake pipes to confirm no obvious leaks. If the light remains on, use a diagnostic tool to read the fault codes. Avoid randomly disassembling ECU components yourself—it's best handled by professionals to prevent further damage. Regular oil changes are crucial to prevent degraded oil quality from causing chain reactions.
