What's the matter with the fault light of Bluebird engine always on?

ladies and gentlemen, I am 8. The Bluebird bought at 16, when the car is picked up, the engine fault light is always on as long as the engine is started. The car seller says that it is all like that, but it will be gone after running for a while. Is it the same for you? I have run for more than 1 kilometers, and everyone who is still on, I am 8. The Bluebird bought at 16 (check the transaction price | model details), when the car is picked up, the engine fault light is always on as long as the engine is started. The car seller says that it is all like that, and it will be gone after running for a while. Is it the same for you? My car has been running for more than 1 kilometers, and it's still on. If the water thermometer can't rise to the ideal temperature (usually 9 degrees) for a long time in the car, the engine fault light will light up. Although there are many reasons for turning on the light, I feel that the low-grade gasoline is used due to the high compression ratio due to the power age of the squeezing engine. I think the poor quality of gasoline or the low-grade gasoline used is the main reason. I suggest that the gas station with large traffic flow should be filled with high-grade gasoline, and the car should run at high speed for a few minutes without shaking, and it should be restored within 2 days. No other reasons can be checked. It is my pleasure to answer the questions of riders. If you are satisfied, please adopt it. Reasons for the engine fault light: 1. If the engine cylinder is dirty and has carbon deposits in it for a certain period of time, some carbon deposits must accumulate in the engine. These carbon deposits themselves will lead to changes in engine design parameters, and at the same time, their properties will be unstable and heat will accumulate. These accumulated heat will lead to disorderly ignition of the engine, thus causing engine knocking. In this case, the engine fault light will light up. What is the reason why the automobile engine fault light is on? 2. The poor combustion state of the engine is the main reason why the engine fault light is on. In automobile design, in order to ensure that the engine is in a good working condition and the normal working life of the engine, an oxygen sensor is designed and installed on the engine to monitor the combustion state of the engine. Once the engine is in a bad combustion state, it will not only pollute the environment, but also lead to fuel waste and excessive engine wear. 3, poor fuel quality Many riders who find that the engine fault light is on have a feeling that the engine fault light suddenly lights up after adding a box of oil. Because the engine has requirements for the quality index of oil, especially with the increasingly high requirements for engines in various specifications, the quality index of oil is also increasingly high. In real life, after all, some gas stations can't provide fuel to meet the requirements of high-performance engines completely according to the specifications, which leads to engine failure lights coming on from time to time. Solutions for engine failure lights 1. Cleaning the engine Once the engine failure lights up, the owner should clean the engine in time. At present, there are two correct cleaning methods: (1) Go to the repair shop to clean the carbon deposit with a special cleaning agent. (2) Clean the whole fuel system by yourself with good fuel additives, including removing carbon deposits in the cylinder. 2. After cleaning the engine with higher grade gasoline, the compression ratio of automobile engines that meet the national four emission standards is generally above 1., so this kind of car is not suitable for adding gasoline below 95 for a long time. In order to keep the engine in good working condition, the owner can choose to add 95 # or 97 # gasoline, which can usually solve the problem of engine fault light. 3. Improve fuel quality Since domestic fuel can't meet the requirements of current high-efficiency engines for the time being, improve the quality of fuel by yourself. For example, it should be the best way to improve the cleanliness of fuel with good fuel additives. Damage caused by the engine fault light: After the engine fault light is on, there are always some abnormal conditions. If it is not solved in time, it will usually be accompanied by the following problems: 1. The temperature of the combustion chamber rises and the wear is intensified, which may lead to early engine damage; 2, the engine noise increases, affecting driving and riding comfort. 3. The increase of automobile fuel consumption wastes petroleum resources and RMB resources; 4. Engine burns engine oil; 5. The quality of automobile exhaust gas becomes worse and pollutes the environment; What should I do if the engine fault light is on? First, check the water thermometer and the oil pressure alarm light. If the water thermometer and the oil pressure warning light don't give an alarm (the pointer thermometer remembers that the temperature should be around 95 degrees), the car can still be driven, but at this time, we must pay attention to controlling the speed and drive to the repair shop for inspection in time. If the water temperature is too high or the oil pressure warning light is on, if you obviously feel that the vehicle is out of order, you should immediately pull over and call the repair shop for help. Will the engine fault light disappear automatically? Once the engine fault light is on, it means that the engine parameters have changed, and excessive carbon deposition is one of the main reasons for the change of engine parameters. If this problem is not solved, the engine combustion state will never be adjusted to the normal state, and the engine fault light will of course always be on and will not disappear automatically. Can the engine fault light be turned on? Just because the engine fault light is on doesn't mean that the engine can't work. First of all, when the fault light is on, it is necessary to check and repair. If you happen to be near the repair shop, you can check it at any time. If you are far away from the repair shop and happen to have no time to check it, you can do your thing first. There are just a few points to note. 1. Don't drive as usual during driving. It's best to keep driving at a low speed. 2, always pay attention to whether the oil meter is an alarm, if the oil is seriously missing, it is absolutely impossible to drive. 3. Always pay attention to whether the water thermometer (antifreeze) gives an alarm. If the water temperature is too high and you drive for a long time, it is certain that the car will break down. The engine fault light is on. Usually, if there is no obvious fault, it is ok to drive cautiously at low speed. There may be some minor faults, or there may be no faults (false faults), but if the engine has obvious faults, such as serious abnormal noise, serious jitter, engine smoke, etc., you must not drive on the road. It is best to contact the repair shop and wait for rescue. @219
