What is the reason why the new car has two engine failures?

If the instrument indicator is not lit, first check the power supply fuse of the dashboard, and replace it if it is blown. Disassemble the dashboard, the lights are generally at the back of the dashboard, replace the lights that are not lit, and generally the individual lights are not lit to indicate that there is no problem with the fuse and wire, the main reasons are as follows

1. The lamp of the dashboard is damaged and needs to be replaced in time;

2. If the power supply line of the dashboard is broken, there is an open circuit or short circuit, which will also cause the car dashboard to not light up;

3. If the power supply fuse of the car dashboard is broken, there will naturally be no power supply, and the dashboard will not light up.

Precautions in the use of the car dashboard:

1. When the indicator light is on, the odometer should be observed immediately, if the cumulative mileage reaches or exceeds l00,000km, the timing toothed belt must be replaced, otherwise the timing toothed belt may break, so that the engine can not work normally.

2. After replacing the new timing toothed belt, it is necessary to open the rubber plug outside the reset switch on the mileage dial, and press the reset switch inside with a small round bar to extinguish the indicator light of the timing toothed belt.

3. After replacing the new timing toothed belt, remove the odometer and adjust all the readings on the odometer to the 0 position.

After the engine fault light of the new car is on, first pay attention to whether the engine is running normally, whether there are problems such as shaking, black smoke or difficult to start, and if so, try not to start again. If the engine is running normally and can be driven normally, please go to the service station as soon as possible to find out the cause.

What should I do if the engine fault light of a new car is on.

The reason for the fault light is well confirmed, and the service station can easily read the fault code as long as it is connected to a portable diagnostic instrument, and obtain the fault information for targeted repair. If the engine is running normally, the owner can also try to gently plug in the wiring harness connectors, which may be caused by a false connection somewhere, or repeatedly dial the key to the ON gear to see if it can be eliminated.

When the engine fault light is on, it can be divided into three situations, each of which has a different way to deal with it

1. The car can't start, this may be caused by the failure of the fuel pump or ignition parts, then let's call ** for help, after all, the chance of ordinary people wanting to make the car come back to life by themselves is very small.

2. The fault light is on, but there is no abnormality in driving, this may just be a sensor failure, this situation can continue to drive temporarily, but it is best to slow down at low and medium speeds, and the next destination is of course the repair shop.

3. The engine fault light is on, the vehicle can be driven, but there are symptoms such as severe shaking and acceleration weakness, don't take the courage to try your luck in the face of this situation, obediently stop and call for rescue.

Don't worry about the failure of the new car in 3 months, let's take a look at the specific fault phenomenon. Suddenly the engine fault light turned on, and the after-sales reply should be a fuel quality problem (all the way to add 95 gasoline, to the 4s inspection after the conclusion is also a fuel problem, it is recommended to buy 4s fuel mixture, drive home a week after refueling and then add fuel mixture, the next day the engine fault light is on again, what is the reason, how to solve it. Failure analysis This situation has nothing to do with the quality of the car, if the oil circuit is too dirty, the use of detergent once is not clean, it needs to be done many times.

Because the initial oil of this kind of imported car may deteriorate very badly, the reason is that the initial oil is transported to the customer in the initial stage, the fuel time is too long, the initial fuel is seriously deteriorated, and a large number of colloidal impurities appear, which finally leads to the continuous contamination of the subsequent fuel, similar to bacteria can continue to corrupt new fuel, resulting in a long-term lack of fresh fuel can be used. The fault light will only light up because of the accumulation of multiple combustion emission failures to a certain number of times, although it is a new car, but it is unavoidable that the problem of the initial fuel is installed. Because the initial fuel will deteriorate very badly, it will become a fuel containing a large number of oil bacteria, constantly polluting fresh fuel, and emission failures will occur many times, but they are not displayed, only the data stream exists, and when it is accumulated to a certain number of times, the emission failure light will be lit, and the car has been problematic many times.

It means that the fuel tank is too dirty, a lot of gum impurities, and the moisture density is high and precipitated underneath. Then the fault can be reported, which means that there is no problem with the sensor. But why is the fault light on after refueling, this is most likely because the impact force of refueling is relatively large, and after mixing a lot of colloidal impurities at the bottom of the fuel tank, it will break out of an extremely bad burning time period, and finally the light will be turned on after more times.

Solution Use the fuel additives of the national VI standard, after cleaning 5 times in a row and thoroughly cleaning, the oil circuit is clean and the combustion is good, there will be no more such failures. There is also such a situation in the circle of car friends, and it will be completely healed after cleaning it a few times in this way. Because the probability of bad oil deterioration is high, we have analyzed it above, so it is best to clean it thoroughly to prevent a lot of unfavorable conditions for the engine in the future.

Clean oil circuits have nothing to do with new and old cars, but are directly related to the severity of fuel deterioration before. In addition, the use of additives and the use of effective additives are two different things, it is best to use this kind of additives suitable for domestic oil products, targeted and strong effect. Imported additives are developed for exporting countries, and there is a big gap between the situation of domestic oil products.

Hello, I am helping you to inquire about the relevant information, please wait for a while and get back to you immediately.

Hello dear, here for you to find out. The solution to the failure light of the car engine is as follows: 1. Check the status of the car engine in time; 2. Check the status of the sensor, air flow sensor and spark plug parts of the car; 3. Check whether the car has detonation; 4. Check whether the ignition coil is faulty; 5. The engine has serious carbon deposits.

The reasons for the failure light of the automobile engine are: 1. The poor quality of gasoline leads to insufficient combustion of the mixture in the cylinder, resulting in carbon deposits; 2. The mileage of the engine is too long, and the working characteristics of the spark plug are weakened; 3. Aging of vehicle machinery; 4. Water temperature, crankshaft position, air flow, inlet air temperature, oxygen sensor damage, poor contact or signal interruption.

It depends on the circumstances.

If the electric door lock is opened, this situation occurs before it is started, which is the system self-test state, and the indicator lights of the instrument panel disappear when the ignition is started, indicating that there is no problem.

If the fault light is still on when it is started, this is not necessarily a real fault, but it should be taken seriously. You can give 4S points **, let the master come and check it, if they say let you drive over, then drive over, because it is free of charge for maintenance during the warranty period.

Hello, I have also seen someone mention this situation you said, maybe the oil problem, maybe the induction problem, maybe the engine really has a problem, but generally according to the text description of the words it is difficult to find and find the specific reason, the best is to find a nearby professional and reliable maintenance shop or after-sales call the master to actually check, only the specific inspection can be effectively solved.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Good evening, the EFI car electronic control system is mainly composed of sensors, actuators, computer board wiring harnesses, fault lamp assembly, ** abnormal will light up the fault lamp, at this time you need to use the decoder to call the fault code for troubleshooting. This part of the old car is still new.

If there is no malfunction, it is generally caused by bad fuel and needs to be used with 97 gasoline.

There are too many reasons that induce engine failure lights, such as poor engine condition caused by bad gasoline oil quality can also cause this! There is also the possibility of a failure of one of the engine's sensors.

The main reason for the engine light of the new car is related to the circuit, and the computer is used to identify the fault code to determine the problem.

Hello, the fault light of the engine is on, there are too many reasons, it is recommended to go to the four S store to test it with a computer. Most of it is due to the fuel emission system, or the quality of your gasoline

Hello, there are many reasons why the engine failure light is on, and bad oil will also cause the engine failure light, so it is recommended that you go to the store to check it.

Hello, the engine failure light of the new car is on, it is best to go directly to the 4S shop for direct inspection and maintenance, if the vehicle is powered on for self-inspection, the ignition is generally extinguished, this is normal.

Hello landlord. If the fault light is on, it is necessary to connect the diagnostic instrument to see what the specific fault code is, so as to solve the problem more efficiently. It is recommended to go to a 4S shop or repair shop to have a look.

Hello, the engine fault indicator of the new car needs to be lit up The old car is the same, you need to use the computer diagnostic instrument to detect the specific fault code, and repair and eliminate the fault according to the fault code prompt.

New cars are generally the fault light of the vehicle self-inspection, if it is still on after ignition, it is necessary to check and confirm the fault.

Hello, the vehicle engine fault light has been on, you need to go to the 4S shop to check the fault code to know the specific problem.

If the engine fault light is on, there will be many reasons, it is recommended that you go to the 4S shop to read the engine fault code.

If the engine fault light of the new car is on, you can go directly to the 4S shop for free inspection and maintenance.

Si Youpu said that the car, the new car will turn on the fault light.

Hello, I have also seen someone mention this situation you said, maybe the oil problem, maybe the induction problem, maybe the engine really has a problem, but generally according to the text description of the words it is difficult to find and find the specific reason, the best is to find a nearby professional and reliable maintenance shop or after-sales call the master to actually check, only the specific inspection can be effectively solved.

This needs to be checked with a diagnostic computer to know the result.

This requires the help of a decoder to look for faults.

Just look at the faults with the help of the decoder.

The engine fault light, battery light, and oil lamp are always on as long as the key is placed in the ON place before the fire is on, and it is normal, and it is normal to turn off after the car, and it is a problem to be on again.

Si Youpu said that the car, the new car will turn on the fault light.

Hello, new car breakdown, how many kilometers of your car is that year! I hope mine can be helpful to you, and if you don't understand, you can ask me if you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

There are generally several reasons for the engine failure light: the fuel supply system, ignition system, air intake system, exhaust system and various sensor components are faulty. You can use the elimination method to eliminate one by one, and if you encounter the engine light during driving, it is best to go to the repair shop to check the fault code.

First of all, it needs to be clear that when the ignition switch is turned on, the dashboard indicator light will be lit, which is the self-diagnosis of the car system, and it will automatically go off after a period of time.

1. Engine fault lamp.

Causes: Poor combustion state, engine knocking, poor fuel quality, excessive carbon deposits in the engine.

Second, the battery fault lamp.

Reason: Battery loss and scrapping, power system failure.

3. Oil warning light.

Causes: insufficient oil volume, high engine temperature, improper oil selection, blockage in the oil pipeline.

Fourth, the tire pressure warning light.

Cause: Broken and leaky tires, damaged tire pressure sensors.

5. Brake system fault lamp.

Reason: The handbrake is not put down, the ABS function fails, the brake fluid does not meet the requirements, and the braking system is abnormal.

6. Water temperature alarm light.

Causes: Engine water temperature is too high, lack of coolant, thermostat failure, water temperature sensor damage.

In summary, the above is the more common car fault light, the new car fault light can reflect the situation to the 4S shop, and the one within the warranty period can be replaced or repaired free of charge.

Hello, the engine fault light of the new car is on, there are the following reasons: 1. Sensor problem, the sensor mentioned here includes 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 be on. 2. Maintenance problems, poor engine maintenance is the most common cause of engine failure.

We know that vehicles have 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 that you should care about your car. 3. Oil quality, the oil quality mentioned 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 generally recommends the owner to use which grade of fuel, what 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.

4. 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 engine carbon deposition or knocking problems, and these will eventually be detected by the engine's oxygen sensor, and after being reported to the ECU, the fault light will naturally be lit as a warning.

5. Air intake problem: When the engine burns, it needs to be intake, the air filter 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.
