Can the engine fault light continue to turn on?

It can be opened to a 4S store.

If the engine fault light is on, there is no abnormal noise in the cabin, there is no other abnormal prompt in the instrument, the vehicle power is not affected, and the gearbox upshift is not affected, you can continue to drive and stop the 4S shop for further investigation, because the intake and exhaust may cause the engine fault light to be on, and the specific problem is analyzed.

There are two situations when the engine fault light is on: the yellow symbol light indicates that the engine is faulty, but the fault does not affect the normal operation of the engine, but it must be maintained.

The red symbol light indicates that the engine has a serious fault, and it needs to be repaired immediately under normal circumstances, if it is under special road conditions, it can be used in an emergency, but it is necessary to pay attention to the working status of the engine at all times; But as a reminder, EFI engines have self-protecting control systems, which won't let you ignore the life or death of the engine.

Electronically controlled engine maintenance points, control gasoline injection system has high requirements for the cleanliness of gasoline, and deleaded gasoline with the grade and quality fully meets the requirements should be used. Fuel filters are replaced regularly to prevent foreign objects in the fuel from clogging the injectors.

Use the power supply in strict accordance with the requirements. The battery must be installed with the correct polarity, otherwise the electronic components will burn out. Try to avoid severe vibration of the computer, and prevent moisture from soaking into the parts (parts) of the electronic control system.

When the engine cannot start normally due to the loss of battery power, the battery should be charged or replaced with a new battery in time, and try not to use the method of jumper circuit to start the engine.

An engine is a machine that can convert other forms of energy into mechanical energy, such as internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. For example, the internal combustion engine usually converts chemical energy into mechanical energy. An engine applies to both a power generation unit and an entire machine including a power unit (e.g

gasoline engines, aero engines).

The engine was first born in England, so the concept of the engine also originated from the English language, and its original meaning refers to the "mechanical device that produces power".

The engine fault light is on, but when the car is driven, as long as there are no symptoms such as shaking, frustration, and black smoke from the exhaust pipe, you don't have to worry, you can drive it with confidence, mainly because of poor combustion, false failure caused by poor contact with the oxygen sensor, pull the engine at high speed, clear the oil circuit, and after changing the fuel, it will return to normal after a period of time. On the contrary, it is necessary to use a computer to read the fault code for symptoms.

The yellow fault light of the engine is on, on or not With the development of automotive technology, there are more and more functions on the car, and the development of automotive technology is very rapid. However, this also makes the phenomenon of car engine failure lights on more and more. Car fault lights often appear in the process of driving, or the moment the car is ignited, usually red or yellow lights, once lit, in most cases will not disappear automatically, in a few cases will disappear automatically, then, the engine fault light can continue to drive after the car is on?

When can I continue driving? This kind of yellow fault lamp is mainly caused by poor emissions: First, the exhaust emission is not up to standard:

For example, poor fuel, three-way catalytic converter failure, excessive carbon deposition in the intake pipe, blocked fuel injector, oxygen sensor failure, occasional lack of fire in the engine, etc., will lead to the engine failure light to be lit, among which the engine failure light is the most caused by poor oil quality, many times many riders have a feeling, that is, the engine fault light suddenly lights up after adding a tank of oil to the field, because the engine has requirements for the quality index of the oil, leaded gasoline will also cause oxygen sensor poisoning, Therefore, oil quality is the main cause of insufficient engine combustion, which leads to the engine failure light on. This kind of failure is not a big problem in the initial stage of use, but long-term use may cause oxygen sensor poisoning, three-way catalytic converter failure, etc., the above spare parts are not cheap, it is recommended to deal with it as soon as possible to reduce the risk of failure. It is recommended to use 3-5 times of additives such as general stock solution, and it will disappear after running more than one more time.

Do not drive vigorously at this time, so as not to cause greater damage due to excessive pressure on the fuel injector.

Use the decoder to read the fault**, and then clear the fault**, the reason, 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, and at the same time, the vehicle will also have oil leakage, large oil consumption, and power loss.

The engine fault light is on and cannot be turned on.

Once the engine fault light is on, the owner can check it by following these three points:

1. First of all, check whether the engine is running normally, whether there is shaking, black smoke or difficult to start, try not to start again, there is a high probability that the engine is wrong.

2. If the engine is running normally and can drive normally, please go to the service station as soon as possible to find the reason.

3. If the engine is running normally, the owner can try to plug in the wiring harness joints, which may be a virtual connection somewhere, or you can repeatedly dial the key to the ON gear to see if it can be eliminated.

The reason for the engine failure light is very well confirmed, and the service station only needs to be connected to a portable diagnostic instrument to read the fault code and obtain fault information for targeted repair.

After the engine fault light is on, if it is not solved in time, it will usually be accompanied by the following problems:

1. The quality of automobile exhaust gas deteriorates and pollutes the environment.

2. The fuel consumption of automobiles increases and wastes petroleum resources.

3. The temperature of the combustion chamber rises and the wear intensifies, which may lead to early damage to the engine.

4. The engine burns oil.

5. The increase in engine noise affects the comfort of driving and riding in the car.

It is best not to continue driving when the engine fault light is on, because the fault light is on, which means that there is a problem with the car, and drive to the nearest station as soon as possible to test the car.

Generally speaking, there are two situations when the engine fault light is on:

1. The yellow symbol light indicates that the engine is faulty, but the fault does not affect the normal operation of the engine, but it must be tested and repaired.

2. The red symbol light indicates that the engine has a serious fault, and it needs to be repaired immediately under normal circumstances. <>

After the engine fault light is on, if it is not solved in time, it is usually accompanied by the following front pin problems:

1. The quality of automobile exhaust gas deteriorates and pollutes the environment.

2. The fuel consumption of automobiles increases and wastes petroleum resources.

3. The temperature of the combustion chamber rises and the wear increases, which may lead to early damage to the engine.

4. The engine burns oil.

5. The engine noise increases, affecting the comfort of driving and riding.

It is recommended to send it to the 4S shop for repair in time, and the fault light is on, for the following reasons.

1. When the ignition switch is turned on, the instrument panel indicator will light up, which is the self-diagnosis of the car system, and it will automatically turn off after a period of time.

2. The engine fault light is on, indicating that the combustion state is not good for the car, the engine is detonated, the fuel quality is not good, and the engine has too much carbon deposit.

3. The battery fault light is on, indicating that the battery is scrapped due to power loss and the power supply system is faulty.

4. The oil warning light is on, indicating that the oil quantity is insufficient, the engine temperature is too high, the oil is not properly selected, and the oil pipeline is blocked.

5. The tire pressure alarm light is on, indicating that the tire is damaged and the sail base air is leaking, and the tire pressure sensor is damaged.

6. The fault light of the braking system indicates that the handbrake is not released and down, the ABS function is invalid, the brake oil does not meet the requirements, and the braking system is abnormal.

7. The water temperature alarm light is on, indicating that the engine water temperature is too high, the coolant is missing, the thermostat fails, and the water temperature sensor is damaged.

The engine fault light is on, can the car continue to drive? Old driver: Of course not!

What should I do if the engine fault light is on? First check the water temperature gauge and the oil pressure alarm light. If the water temperature gauge and oil pressure warning light do not alarm, the car can still be driven, but at this time, you must pay attention to control the speed of the car and drive to the maintenance station in time for inspection.

Answer hello, the exhaust fault light can continue to open, not all exhaust fault lights can not be turned on, if the engine fault light is on, there is no abnormal sound in the cabin, the instrument has no other abnormal prompts, the vehicle power is not affected, the gearbox upshift is not affected, you can continue to drive.

If the engine fault light is on, there is no abnormal noise in the cabin, there is no other abnormal prompt in the instrument, the vehicle power is not affected, and the gearbox upshift is not affected, you can continue to drive and stop the 4S shop for further investigation, because the intake and exhaust may cause the engine fault light to be on, and the specific problem is analyzed.

This is commonly referred to as the exhaust gas fault lamp, also known as the EFI system fault lamp. As long as there are no special abnormalities in the engine power and sound, it can still continue to drive. Because there is a substitute bug program in the ECU.

Once one of the many sensors has a sensing failure, in order to ensure the normal operation of the engine, the ECU will replace the parameters of the faulty sensor according to the pre-set backup parameters to avoid vehicle breakdown. For example, if the water temperature sensor is broken, the ECU will use a backup value of 80 degrees as the control parameter for fuel injection and ignition. So it can be opened, but it must also be repaired in time.

If not addressed in a timely manner, the following situations may occur:

1. The quality of automobile exhaust gas deteriorates and pollutes the environment.

2. Increased fuel consumption of automobiles;

3. The temperature of the combustion chamber rises and the wear intensifies, resulting in accelerated engine wear;

4. The engine noise increases, affecting the comfort of driving and riding.

The engine fault light is on, as long as there is no abnormal noise, no red light is on, it can be turned on, no problem.

The engine fault light is a yellow light, which means that you can drive to the pit for maintenance, and the red light will not work, as long as it is on, you can't drive.

The fault light of the engine is on, if the oil and antifreeze are not missing, and. The acceleration performance of the engine is also normal, the sound of the engine is also normal, and there is no change before, then in this case it may be that the engine burns badly, or a sensor is not working properly, in this case, the vehicle can still be driven, but do not run for a long time in time. Go to the repair shop in time and use the computer to detect and repair it.

If the engine fault light is on, there is no abnormal noise in the cabin, there is no other abnormal prompt in the instrument, the vehicle power is not affected, and the gearbox upshift is not affected, you can continue to drive to the repair shop for further investigation.

There are many reasons why the engine fault warning light is on, which may be the poor combustion state in the cylinder, engine knocking (the engine combustion is abnormal, the pressure curve appears high-frequency, large fluctuations, and will break through the cylinder block in serious cases), carbon deposits inside the engine, etc.
