The engine yellow light is a warning light on the dashboard of the vehicle, commonly known as the "engine fault indicator light". This yellow light indicates that some engine failures are happening and need to be repaired in time. If it is not repaired, it will pose a potential threat to the safety of the vehicle.Why does the engine yellow light turn on? When there is a problem with the engine, the vehicle's electronic control unit (ECU) will record the fault code and send signals, which are converted into information on the dashboard, including the engine yellow light. Therefore, when the engine yellow light turns on, it means that the engine has failed to a certain extent. There are many reasons why the yellow light of the engine turns on, for example: 1. Sensor failure: The sensor in the vehicle will sense many parameters, including oil pressure, water temperature, oxygen content and emissions. If one of the sensors fails, the engine fault indicator light will light up. Two. Spark plug failure: The spark plug is an important part of the engine. If the spark plug fails, the engine will not work properly. 3. Overheating: If the engine of the vehicle is overheated, the engine fault indicator light will light up.Four. Engine failure or engine damage: In some cases, the engine fault indicator light may be a serious fault sign, telling the owner that the engine may need to be repaired or replaced. What should we do? Once the engine yellow light comes on, you should find a safe place to stop as soon as possible and restart the engine. If the yellow light disappears, it may just be a temporary failure. And if you continue to drive, it may aggravate the failure and cause more damage. If the yellow light continues to be on, you need to go to a car repair shop or a professional technician for inspection and repair. Before maintenance, make sure that the engine fault indicator light is cleared and the fault code is recorded. This helps the repair staff to quickly find and solve the fault. Although the engine yellow light does not necessarily mean that you need to stop immediately, if the situation is very urgent or the engine yellow light turns red, you should stop immediately.A red light indicates a serious failure, which may cause the vehicle to be undriven and even cause an accident. Conclusion The yellow light of the engine is a kind of warning to remind the owner that the engine is faulty. If you find that the engine yellow light is flashing, please don't ignore it. Stop the car and check the fault, or go to the repair shop to seek help from a professional technician.
