What should I do if the engine failure light of a diesel car is on?

1. You should find a safe place to stop and check whether the engine has abnormal noise, check whether there is oil leakage, if there is no abnormality after the inspection, it may be a false alarm of the fault sensor light. When the pollution light is on, the engine action does not shake or shakes slightly, at this time, the owner does not need to worry when using it, it can be used normally, and it can be checked or maintained when there is time or convenience.

2. The vehicle fault light is generally caused by the fuel emission system, you start and extinguish the vehicle when the fault light is on, and after starting and extinguishing the car three times, you observe whether the fault light is still lit when starting the vehicle, and if it is still lit, you need to go to the store in time to check the fault code to see whether it is the engine problem or the sensor failure.

There are many reasons why the diesel engine fault light is on, such as: 1. The car thermostat cannot be turned on, and the coolant cannot be circulated; 2. The radiator or engine water jacket is blocked, so that the coolant cannot be circulated and cooled normally; 3. The impeller of the water pump is corroded and aged, which makes the pump water pressure insufficient; 4. The heat sink of the water tank is abnormal, which may be deformed or blocked by foreign objects, which will affect the heat dissipation.

In addition, the cause of the diesel engine failure light may also be the engine ignition too late, the water pump belt aging too loose, etc. All in all, the diesel engine fault light is on, indicating that the vehicle engine is faulty, at this time, you should find a safe road section to stop as soon as possible, and wait for a while for the engine to cool down before the engine can be checked and repaired. Although sometimes the diesel engine fault light is lit, it may be just that the sensor is damaged and cannot detect the corresponding vehicle condition information, but the owner had better not take a chance to continue to use the car to avoid danger.

When the engine fault light of the car with diesel engine is on, it means that the engine of the car is faulty, and it is necessary to check whether there is a problem with the electronic control system of the car engine, which is generally caused by the damage of an electronic component of the car.

Personally, it is recommended not to use the vehicle as much as possible, call the insurance company** to contact the free tow truck and send it to the auto repair shop for inspection, and then use it after repair.

The reason why the engine failure light is on.

1. The combustion state is not good.

Poor engine combustion condition is the main reason why the engine failure light is on. In the design of the car, in order to ensure that the engine is in good working condition and ensure 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.

2. The fuel quality is not good.

Many riders who find that the engine fault light is on have a feeling: that is, the engine fault light suddenly turns on after adding a tank of fuel. Because the engine has requirements for the quality index of oil, especially as the requirements for the engine are getting higher and higher in various specifications, the quality index of the oil is also getting higher and higher.

3. The inside of the engine cylinder is not clean, and there must be some carbon deposits inside the engine after a certain period of use, which will cause the engine design parameters to change, and its properties are unstable and heat is accumulated, and the accumulated heat will lead to disorderly ignition of the engine, thereby causing engine detonation. In this case, the engine fault light is also illuminated.

The engine fault light is on the solution.

1. Clean the engine.

Once the engine failure light is on, the owner should clean the engine in time, and there are currently two correct cleaning methods:

1) Go to the repair shop to clean the carbon deposits with a special cleaning agent.

2) Clean the entire fuel system with good fuel additives, including removing carbon deposits in the cylinder.

2. Add higher grade gasoline.

After the engine cleaning, because the compression ratio of the current automobile engine that meets the national IV emission standard is generally above, this kind of car is not suitable for long-term gasoline below 95. 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 the engine failure light on.

3. Improve fuel quality.

Possible causes of car engine failure lights on:

1, the vehicle fault light is generally caused by the fuel emission system, you start and extinguish the vehicle when the fault light is on, and after starting the vehicle three times, you observe whether the fault light is still lit, or it is still lit, you need to go to the store in time to check the fault code, to see whether it is an engine problem or a sensor failure, or it may be an occasional failure can not be checked in time.

2. When the computer receives the parameters of the oxygen sensor, the exhaust emissions seriously exceed the national legal standards, and the internal program of the computer cannot be corrected to the standard range, at this time, the engine control computer will issue a warning light (yellow pollution lamp on) through the instrument to remind the owner to the maintenance station to check the cause of the engine pollution emission lamp.

The automobile engine is the machine that provides power for the car, and it is the heart of the car, which affects the power, economy and environmental protection of the car. According to different power**, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids.

Common gasoline engines and diesel engines belong to reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy of piston movement and output power to the outside world. The gasoline engine has high speed, small quality, low noise, easy starting, and low manufacturing cost; The diesel engine has a large compression ratio, high thermal efficiency, and better economic performance and emission performance than the gasoline engine.

In addition to the use of gasoline and diesel, vehicles that use other new energy sources are called new energy vehicles, including pure electric vehicles, hybrid electric vehicles, fuel cell vehicles, gas vehicles, bioethanol biodiesel vehicles, and hydrogen-powered vehicles. Most of the new energy vehicles on sale in the Chinese market are hybrid vehicles, but at present, pure electric vehicles have been taken as the main direction.

Hello, there are many reasons why the fault light is on, the water temperature, the oil lamp is normal, and you can not feel that the car is bad, you can drive to the nearest repair shop to check the fault code.

The exhaust gas purification liquid (urea) used in China V is gone. The car can be driven but the emissions are not up to standard, and the fuel consumption is high.

Hello, the yellow light is problematic but can be turned on! But you have to know what the fault is to know what the impact is! It is advisable to check it out.

In the event of a breakdown, park the car to a safe mountain belt as soon as possible, and then find a way to ask for help.

Vehicles have warning lights, such as something like a faucet, which is often referred to as an engine failure, etc. This indicator light usually lights up when the vehicle is powered on and turns off when it actually starts. But lit up due to vehicle problems.

This light is often referred to as an engine failure light, but it is actually a warning light that emits a warning light. Normally, this light will not go out. This means that the vehicle's emissions exceed the standard and repairs must be made.

Due to carbon deposits. Emissions are mostly substandard. Therefore, if the warning light is on, the carbon deposition will be more severe.

For the carbon deposits that have formed, the only way to clean them is to clean them, and there is no easy and quick way to dispose of them. Carbon deposits occur reliably, but the speed and amount produced are related to many of the driver's car habits. In general, you should refuel regularly, minimize idle time, and use the refueling step regularly.

This is an effective means of slowing down carbon production, with the main aim of helping gasoline burn completely and reducing residues. How is that possible to solve the problem.

1.Start and shut down the vehicle 3 times in a row, or unplug the negative terminal of the engine battery and wait 30 seconds before connecting. Once the above methods are complete, check the engine fault indicator on the dashboard. This method is only used if there is a failure in the engine.

2.The engine exhaust system fault indicator is mainly due to three-way catalysis.

The oxygen sensor in the system is damaged, mainly due to the quality of the household oil or the three-way catalytic converter poisoning. If the indicator light is lit during operation, please slow down immediately and drive to the nearest repair shop. Gas stations are undergoing maintenance.

3.If the fault light is illuminated and the vehicle will not start with severe shaking, acceleration and other symptoms, it is recommended that you continue driving. Stopping the drive not only prevents further damage to the rock-matched engine, but also protects you and others.

Hello dear! If the diesel engine fault light is on, first check the water temperature gauge and oil pressure alarm light. If the water temperature gauge and oil pressure warning light are not alarmed, 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.

Chai Xian can be divided into three situations after the engine fault light is on, and each situation has different coping methods: the first is that the car cannot start, which may be caused by the failure of the fuel pump or ignition parts, then we will directly call ** for help, after all, the chance of ordinary people trying to bring the car back to life by themselves is very small. The second is that the fault light is bright, 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.

The third is that the engine fault light is on, and the vehicle can be driven, but there are symptoms such as severe shaking and acceleration weakness.

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

The first is that the car can't start, which 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.

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

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

Summary. Hello, first check the water temperature gauge, oil pressure alarm light. Drain the water out of the water separator, and if that doesn't work, you need to replace the sensor. It is recommended to go to the repair shop and read the fault code with the fault code.

What should I do if the diesel contains water and the engine fault light is on.

Hello, first check the water temperature gauge, oil pressure alarm light. Drain the water out of the water separator, and if that doesn't work, you need to replace the sensor. It is recommended to go to the repair shop and read the fault code with the fault code.

The display screen is the alarm with water in fuel?

There is also no drain valve under the diesel filter.

First, open the hood and place the container at the end of the ethylene hose under the drain plug of the oil-water separator; Then loosen the drain plug in a counterclockwise direction, and operate the diesel filter to drain the water from the manual fuel transfer pump until the fuel water separator is filled with fuel; Tighten the excretory plug in a clockwise direction to drain the water through the void; Finally, start the diesel engine to confirm that there is no oil leakage at the discharge plug, and check whether the indicator light of the oil-water separator is off.

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

The first is that the car can't start, which may be caused by the failure of the fuel pump or ignition parts, so call ** for help.

The second is that the fault light is on, but there is no abnormality in driving, which may only be a sensor failure, and this situation can continue to drive temporarily.

The third is that the engine fault light is on, and the vehicle can be driven, but there are symptoms such as severe shaking and weak acceleration, and in the face of this situation, it is necessary to stop and call for rescue.

The engine fault light is lit, and the fault code can be called up by using the computer detector, and then repaired according to the fault code. After a certain period of time and mileage of the vehicle, the air intake system and fuel system will more or less produce some carbon deposits, affecting the normal operation of the engine, so that the exhaust emissions exceed the standard, modern engine computers can detect the working condition of the engine, if the range value is exceeded, the fault light will be lit. Due to carbon deposits and impurities, just clean it.

1. First of all, although the fault light is on, but the car does not have a big problem, and can continue to drive, then, it is necessary to consider whether the sensor is faulty, at this time do not have to worry too much, it will automatically recover, or because of the interference of some external conditions, in fact, it should not affect the vehicle driving, but may have a certain impact on emissions. In this case, you can continue to drive for the time being, be very careful during the drive, and have time to go to the factory for testing.

2. If the fault light is on, there is a problem with a certain part of the car, or the car is difficult to drive, then it cannot continue to drive at this time, and it is called a rescue trailer. Because the car has a breakdown and there is a serious problem, continuing to drive will aggravate the problem, or the resulting problems will gradually accumulate and develop other problems, so it is not recommended to continue driving.

3. Take care of the car, if the engine fails, you should do it in time, don't wait for the problem to deteriorate, and don't take the risk of driving a faulty car.
