The Yuejin card has a fault code similar to a laser light, and it will be powered off after it appears.

The reasons leading to the power decline are: excessive carbon deposition in the engine, stuck throttle, insufficient oil supply, etc. And it may also be a gearbox problem. If there is a fault light, it is recommended to contact the after-sales computer to read it and carry out targeted treatment.

When the engine fault light is on, there is no harm to the engine, that is, the fuel consumption increases. Generally, there is something wrong with the high voltage circuit of the engine or the fuel injector part and the oxygen sensor circuit. First, check whether the high-voltage wire and spark plug have washed the car, got wet in the rain, accumulated water or fallen off.
