What is the reason why the fault light of the diesel car keeps flashing and can t hit the car?

The reason why the indicator light of the car dashboard flashes and does not catch fire is caused by the failure of the car's engine system.

The solution is: if the engine system of the car fails, you need to go to the 4S shop or repair shop of the car in time to overhaul the transmission system to solve the problem of the car indicator light and not ignition.

The car dashboard detection function is due to the fact that the vehicle is equipped with a self-protection system. The purpose is to let the driver know the changes in the information inside the vehicle and prepare for it. In this way, some accidents caused by vehicle problems can be avoided. Therefore, it is normal for the engine light to turn on and off.

Extended Information: The following describes the situation in which the indicator light of the car dashboard is always on.

When the vehicle fails, these faults will generate a string of **, and after the driving computer reads the fault code, it will appear on the dashboard in the form of an indicator. If the engine fault light on the dashboard flashes at the moment of entering the car, it is a reminder that the engine is faulty and that you should pay attention to maintenance when driving cautiously.

The fault signal of the automobile engine is sent by the ECU, and the ECU controls all the electronic equipment of the entire engine, such as electronic throttle, fuel injector, generator, fuel pump, etc., covering various systems such as air intake, exhaust, fuel, ignition, timing, etc. The reason for the flashing of the engine fault light is likely to be that a part of the engine has failed, which is an abnormal phenomenon.

What is the reason why the fault lights of diesel and gasoline keep flashing and the car cannot be hit? This kind of affirmation is what you have always wanted to say, he must be at least the phenomenon of poor contact, if you want to go to the 4S store. The real thing is to fix it.

The CAN bus is faulty, and the CAN interface of the ECU is not in good contact.

2.Excessive dirt and carbon deposits, abnormal air circulation, and inability to accurately control the normal air intake volume, resulting in unstable gas levels and making the engine not work well.

3.The low fuel pressure combined with the poor constant pressure performance leads to a low level of atomization in the system, making it difficult for the car to start.

Extended Materials. About the car dashboard.

1.The car dashboard is a device that reflects the working conditions of each system of the vehicle. Different cars have different gauges. However, the conventional instruments of general automobiles include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc.

2.A variety of indicators or warning lights are made under the instrument panel of modern automobiles, such as coolant level warning light, fuel level indicator, washer liquid level indicator, charging indicator, high and low beam dimming indicator, transmission gear indicator, brake anti-lock braking system (ABS) indicator, drive force control indicator, airbag (SRS) warning light, etc.

The engine fault light is generally faulty engine electrical equipment, you need to use the computer to see what the specific fault code is, and then targeted detection and maintenance, the car is not bored to use the computer to see what fault code, as soon as possible to detect and repair also has a certain guarantee for your driving safety.

In this case, it is also very likely that there is too much carbon deposit, or there is a problem with the quality of the oil added, so the combustion is not good, the efficiency is low, and the power is insufficient. You can try to improve the fuel to promote combustion, clear the carbon deposits, and combustion will completely help increase the power.

Boring, there may be a fuel injector mouth blocked, the EFI engine has high requirements for oil, and it is difficult to ensure the quality of domestic oil products.

Hello dear and happy to answer your <>

Find out the cause of the flashing diesel engine fault light. 1.The water temperature sensor is abnormal.

In order to protect the vehicle's engine and reduce the torque of the engine, the car's fault light will begin to flash, reminding the owner to check the vehicle's condition in time. 2.The inlet pressure temperature sensor is malfunctioning.

If the sensor fails, it will not be able to transmit signals to the engine normally, which will lead to insufficient fuel combustion in the car, weak engine, and even black smoke from the engine on the way to refuel. 3.There is a problem with the oil pressure sensor.

Problems with this sensor will also affect the normal reception of the engine signal as mentioned above, in order to attract the attention of the owner, it will also cause. I hope this service can help you, you can click on my avatar to follow me, and if you have any questions in the future, you can consult me again, and look forward to serving you again. Wishing you well; Happy life, everything goes well [warm] [warm].

Summary. 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 the engine problem or sensor failure, or it may be an occasional failure.

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

What is the reason for the diesel car engine failure light to be on and not working.

This question is up to me, it takes a little time to type, so please be patient.

Vehicle fault dismantling 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 if it is an engine problem or a sensor failure, or it may collapse as an occasional failure. 2.When the computer receives the parameters of the oxygen sensor after the exhaust emissions seriously exceed the national legal standards, the internal program of the computer can not be corrected to the range of the standard, at this time the engine control computer will issue a warning light (yellow pollution light on) through the instrument to remind the owner to the maintenance station to check the cause of the engine pollution emission lamp.
