What should I do if the engine alarm light of Geely Freedom Ship is on?

For the question you asked, the main reason why the engine fault light is on is that the throttle or the engine has too much carbon deposit, and the oxygen sensor is out of balance, which makes the engine fault light on easily. If you drive at a low speed in the urban area for a long time, this phenomenon is easy to appear. It is possible that the insulation layer of high-voltage line is easy to break down after aging, which leads to the engine fault light. Because the self-diagnosis system of the control unit generally does not prompt the fault code of the high-voltage line, it is difficult to find similar problems when they occur. It is necessary to use a special diagnostic computer for special vehicles and cooperate with experienced maintenance personnel to conduct a comprehensive inspection. I hope my answer is helpful to you.
