What's the reason for the major fault light flashing?

[DeMaci]

Introduction to the reasons for the major fault light flashing: Sensor malfunction: If the fault light is on but there are no abnormal driving conditions, it may just be due to a sensor malfunction. In this case, you can continue driving temporarily, but it's best to drive at low to medium speeds. Component failure: The car engine fault signal is issued by the ECU, which controls all the electronic devices of the entire engine. The reason for the engine fault light flashing may be a failure in a certain component of the engine, accompanied by severe shaking, lack of acceleration, and other symptoms. In such a situation, rescue is needed. Fuel pump or ignition component failure: If the car cannot start, it may be due to a fuel pump or ignition component failure. In this case, you can only call for help.
