What are the reasons for the failure light of Chery K50S engine?

It is suggested to use the automobile computer detector to detect the engine system, read the fault code, and then analyze and judge the maintenance according to the detected fault content. The main reason why the engine fault light is on is that there is too much carbon on the throttle or the engine. It is more likely that you are idling unsteadily and the throttle is dirty. When the oxygen sensor fails, the mixture ratio is unbalanced, and the engine fault light is easy to light up. If you drive at a low speed in the urban area for a long time, this phenomenon is easy to appear. Also pay attention to check whether there is any leakage in the fuel injector, which leads to the fuel injector still in the fuel supply state after the throttle valve is closed, which leads to the excessive mixture when driving at low speed, which leads to the unstable idle speed after the fuel is turned off, and even more seriously leads to flameout. You can check from these aspects.
