What is the reason why the engine fault light suddenly turns yellow when Suzuki Yufeng is driving?

Hello, friend, the engine fault light may be the fault of the fuel rail pressure sensor or the fault of the throttle position sensor. It is recommended to go to a 4S shop or a professional maintenance point to check the fault code. If the feedback from the testing equipment shows that there is something wrong with the throttle, it is recommended to clean the throttle first, and see if the fault light disappears after cleaning. If the engine fault light is still on after driving for a period of time, it is that the fuel rail pressure sensor has failed and needs to be repaired and replaced in time.
