The newly bought car found that the engine failure light was on within a few days, what happened?

The newly purchased car, after a few days of driving, found that the engine fault light was on, indicating that its own quality is not good enough, and the engine has a certain fault, so at this time there is a certain potential safety hazard of vehicle driving, and it must be repaired and dealt with in time to achieve the ideal use effect.

Usually, the maintenance of the car must communicate with professionals to learn, master the correct maintenance methods, learn and communicate with others, and pay attention to the following points.

1. Learn to listen. Listening more will allow you to receive more information that is easy to ignore, when to say more, and it is better to listen more and talk less, which will reduce the chance of making mistakes, and also make yourself appear more meaningful and deep.

2. Humble attitude. When speaking, you should put yourself in a humble perspective, not too confident, and not arrogant, otherwise it will affect your interpersonal relationships and work efficiency at work at any time. When encountering things, it is best to discuss them with others, and do not insist on going their own way.

3. Be concise and to the point. The expression of ideas and ideas should be concise and to the point, concise and effective description can better complete the communication of the work, which is the performance of the ability to work, and accurate expression can reduce the working time by more than half.

4. Learn humor. Humor can bring oneself closer to others, but also resolve many conflicts, when there is a misunderstanding of work communication, humor can change the awkward atmosphere, is a skill that must be mastered in the workplace.

5. Use praise more. Only by praising others can you show your courage. Praising the merits of others will gain the respect of others, and at the same time, you will be more motivated to learn.

This needs to go to the store to read the specific cause of the engine failure**, it may be that the circuit is wrong, resulting in a false alarm fault code, or it may be that the engine is really wrong. If there is a real problem with the engine, you can ask them to change the car.

Check the status of the engine, check the car's sensors, air flow sensors, spark plugs, etc., check whether the ignition coil is faulty, and go to the garage to check in time.

There are many kinds of faults that cause the car engine failure light to light up, of course, most of them are in the engine, the core of the car is the engine, and so on agree that the heart engine has a problem, the car must be used abnormally, since it is newly bought, you should immediately drive back to the 4S shop, let them find the reason, if it is a small fault, repair it, if it is not possible to find out or a major fault, ask to change the car.

Before the power is turned on, it is the vehicle self-test, which is normal, and it will be extinguished after starting. If it is still lit after starting or the driving process is bright, the vehicle is faulty and needs to be repaired, and it cannot be forcibly driven, so as not to leave hidden dangers, and contact 4S in time.

If the engine fault light of the new car is on, it may be a false alarm of the driving computer, and the engine fault light can be eliminated by turning off the vehicle and then restarting it. If the fault light has not been eliminated after the vehicle is restarted, it is a quality problem, at this time you can go to the 4S shop to ask professionals to check, and if necessary, you can apply for a replacement car.

The reason is the problem of oil quality, and it is necessary to choose the right oil and gasoline according to the characteristics of the engine. There is a problem with the vehicle's sensors, causing the fault light to come on. Problems with spark plugs or wiring can lead to insufficient combustion of the engine mixture.

Because you're a new car, I personally think it's the sensor or the oil that's causing the problem.

This may be a problem with the quality of the gasoline you added, if there is too much moisture in the gasoline, then the fault light will be on, you can turn on the main driver's seat, and then disconnect the wire on the battery, and then reconnect and start to find that the fault light is off.

The situation that the engine fault light of the new car turns on and off is due to insufficient combustion of the engine mixture due to the substandard fuel quality. In this case, after refueling, add some better quality fuel additives or choose the best fuel station to achieve the purpose of improving the quality of fuel.

The engine failure light of the newly bought car is on in a few days, at this time you need to pay attention, maybe the car you bought may not be a new car, maybe this car is a second-hand car packaged at 4s point to sell to you, this is what you have to look at the nameplate of the car, look at the production date on it, see when it was produced, and then let the manufacturer deal with the problem.

Most of this situation occurs when the battery is out of power and the battery is fully charged. You can take off the negative pole of the battery and wait until two minutes later to put it on again, and then the faulty light will be eliminated.

Is it lit after startup or before starting? It's okay before starting, normal, after starting, it's up to see if there is any abnormality, no abnormality may be a small problem, or even a false alarm, you can go to detect it, if there is an abnormality, immediately turn off the fire and call for rescue.

It should be that the engine water temperature is too high.

When you find that the engine fault light is on, you should pay attention to whether the water temperature of the engine is too high, whether the engine has abnormal noise, and whether the engine is running smoothly.

If you buy a new car for a few days, the engine fault light is on again, then you should pay attention to the fact that the engine fault light is on after the vehicle is ignited, and then the engine fault light is on.

If you find that the engine failure light is on in a few days, you must go to the seller in time to check the notes.

This situation is not necessarily due to engine failure, you can take off the negative pole of the car's battery, wait until two minutes later, and then install it, at this time the engine fault light will not turn on again.

This one needs to be checked at the 4S store. Only in the 4S shop inspection can we find out what is the reason for the engine to turn on the fault light. But you're a new car, I think it's more likely that the system is wrong, and there should be no problem with the engine.

Hello, this kind of thing happens a lot nowadays, and sometimes bad luck can happen to such a thing!

The 4S shop will not return the car to you, but will repair it for you.

Prove that there is a problem with the engine, find a place to sell the car for repairs, and you must be under warranty. And it is time to do a check to prevent this car from breaking down frequently.

In the newly bought car, the engine failure light appeared. There are many reasons for this. It is possible that there is a problem with the integrated route of your vehicle, or there is a problem with the quality of the gasoline you added, anyway, there are many reasons, you can go to some car repair shops to check it.

This, then you still need to find a professional to conduct the test. Generally, there are fewer cases of this kind of fault in new cars, in which case you can ask to replace the engine, or directly replace the car.

Because there are some problems with the engine, you just need to drive to the repair shop, let the repair shop masters check it, see what is the problem and then repair it, you may have a problem with this lamp.

It may be a problem with the sensor, the sensor including water temperature, crankshaft position, air flow, recent temperature, oxygen sensor and other poor contact or interruption of the contact signal of the ECU of the car will cause the engine failure light to turn on.

This needs to contact the 4S store immediately, let them check what the reason is, and find someone who understands to see, if there is a big problem, return or change the car.

Hello, if the engine fault light is on when you start the car and goes off later, then there is no problem, this is the self-check of the car when you start the car.

The car has not been turned on for a few days, and the engine fault light is on, which may be caused by the failure of the engine-related sensors, and then it may be a false alarm itself, which may be a problem with the refueling oil.

Since it is newly bought, the car is within the warranty period of the whole vehicle, and it should be driven to the point of sale for inspection and maintenance in time, and it cannot be repaired privately.

A few days after buying a new car, I found that the engine fault light was on, and it was very likely that the driving computer had a false alarm. It is recommended that you restart the vehicle and see if it is still available.

After a few days of buying a new car, I found that the engine fault light was on, because your engine was indeed faulty, and the fault light was on.

There are many reasons for this problem, don't open it first, go to the 4S store and use the computer to read the data fault code, check the reason, and solve the problem.

1. The engine cannot rotate or rotates too slowly due to the failure of the starting system.

2. Ignition system failure. It is possible that the ignition time is incorrect.

3. The reasons for the high and low engine speed caused by the failure of the fuel injection system include the failure of the fuel injection disc system, the failure of the ignition control system, and the failure of the air intake system.

4. The main reason for poor idle or stalling of the engine is the failure of the idle control system.

5. The internal reasons for the engine fault light to be on: the fuel quality is not good, the inside of the engine cylinder is not clean, and there is carbon deposit.

First of all, light the fault light, so as to tell the owner that the current engine system is faulty, and it should be checked and repaired in time.

Secondly, this fault information will be stored and provided to the mechanic as a reference during maintenance, so as to solve the fault faster.

In addition, in order to ensure that the engine can continue to run in the event of a failure, if the detected fault has little impact on the operation of the engine, the computer will directly ignore it, but in fact, the engine is not in good working condition at this time. If a serious fault is detected, the computer will start the emergency program, and the engine can also work under the emergency program, but generally only to ensure that the engine can continue to run without turning off.

Hello, the engine is faulty, and the new car is only a few days old, and the 4S shop will repair it for you for free.

Call ** to the 4S store and check it out as soon as possible.

Look at the odometer sensor! In new cars, sometimes the odometer sensor will turn on! [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, now the car is used with electronically controlled engines, there are a lot of sensors to detect the working conditions of the engine, and then the signal is fed back to the computer, after the computer analysis and comparison, and then to control the fuel injection ignition and air intake, if there is a problem with the detection of each sensor of the engine, the computer will report the fault code, to remind the owner, the engine needs to be tested and repaired, so we have to find out the reasons for this failure, there are often the following reasons, for reference only: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

The specific situation is analyzed as follows; 1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter, exhaust camshaft and bearing. The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate.

The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter.
