Hello, this should first read the fault code to see what is the reason for the fault lamp lit, if the problem is not big, you can clear it directly.
-
Hello, did you light the fire and wash it in the car, or did you remove it and wash it underneath! If it is estimated that the head of the oxygen sensor is dirty when it is cleaned in the car, it is recommended to use the computer to see what fault code?

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.
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. anti-theft system; If the car's electronic immobilizer fails, or if the immobilizer does not match the engine electronic controller, the immobilizer system will also cause the engine to not work properly and the engine fault light will be lit at the same time.
-
The fault light of the three-way catalytic engine may be caused by the engine itself being too thick or too thin.
Precautions for the use of automotive three-way catalysis: check the working status of the oxygen sensor every 30,000km, and clean or replace the new oxygen sensor in time.
The working principle of the three-way catalytic converter: the purification agent in the three-way catalytic converter will promote the exhaust gas to undergo a certain redox reaction.
-
Although you can use the computer to turn off the fault light, but once the fault light is on, the software will be used to turn it off, so that the oxygen sensor can not read the rear oxygen sensor data, so that there is a certain hidden danger.
-
1. The fault light is on to indicate the three-way catalytic converter.
There are many reasons for blockage, such as poor atomization of fuel injectors, insufficient combustion of the engine, failure of oxygen sensors, temporary poisoning of three-way catalytic converters, failure of three-way catalytic converters, etc.;
2. The working principle of the three-way catalytic converter, when the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of CO, HC and NOx, and promote it to carry out a certain redox reaction.
3. CO is oxidized at high temperature to become colorless and non-toxic carbon dioxide.
Gas; HC compounds are oxidized to water and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. The three harmful gases become harmless gases, so that the exhaust gas of the car can be purified.

Summary. This is because after the replacement of the three-way catalytic converter, the engine combustion is not the same as the original data, you can first add a higher grade of fuel than the original, after a period of driving, the fault light will go out, if the fault light has been on, you need to go to a professional repair shop to check the reason, targeted maintenance!
What is the reason why the three-way catalytic fault lamp is still on?
In this case, it may also be caused by a problem with the oxygen sensor, which may be caused by poor engine combustion. It is also possible that there is a problem with the control computer of this engine, and it may be caused by a problem with the wiring of the oxygen sensor.
This is because after the replacement of the three-way catalytic converter, the engine combustion is not the same as the original data, you can first add a higher grade of fuel than the original, after a period of driving, the fault light will go out, if the fault light has been on, you need to go to a professional repair shop to check the reason, targeted maintenance!
-
The fault light of the new three-way catalytic converter of the car has been on all the time, because the engine combustion is different from the original data.
In this case, you can add fuel that is one grade higher than the original, so that after driving for a while, the fault light will go out.
If, after running for a period of time, the fault light is still on, you have to go to the auto repair shop to check, find out the reason, and solve the problem.
-
The main reasons why the car fault light is on are:
1. The combustion state is not good.
2. Engine knocking.
3. The fuel quality is not good.
4. The inside of the engine cylinder is not clean and there is deposited carbon.
5. The computer cannot obtain the engine data.
Hope, thank you!

Hello, I'm helping you sort out the answers to your questions, please wait a moment Oh ask questions. What happens if the three-way catalytic converter is not good.
Hello, I am your exclusive technician, attentive, careful, and attentive to answer your car's questions, and find solutions and solutions for you to solve the corresponding problems! Your problem is that the fault light is still on after changing to a new three-way catalytic system? The relevant scheme is as follows, the first replacement of the three-way catalysis is not the original factory, there is a problem with the quality itself, the second is the problem of the oxygen sensor, and the third, the engine is not working well, and I personally suggest that this can be judged through the data flow of the oxygen sensor, whether it is the problem of three-way gasification or the problem of the oxygen sensor.
If there is a problem with the quality of the three-way catalysis, the fault light will be lit and the fault code will be reported.

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.
The three-way catalytic converter for automobiles can be cleaned with hydrochloric acid. Non-dismantling cleaning, that is, by "hanging bottles" or adding cleaning agent to the fuel tank, the specific method of "hanging bottles": >>>More
According to the above-mentioned vehicle use phenomenon, combined with the maintenance part and vehicle condition, from the perspective of maintenance cases, this sound nature of the case is mostly the phenomenon of poor bearing lubrication, such as belt tensioner, belt performance, etc., otherwise it will be replaced. In addition, this kind of fault should also be checked on the chassis, such as the exhaust pipe support bottom resonance, the engine lower guard plate is loose, etc., otherwise it can be corrected or tightened. Secondly, combined with maintenance, it is recommended to analyze the engine speed change, so as to judge the performance of the three-way catalytic converter after cleaning, if the engine speed value increases, the sound comes from the chassis or the sound nature changes, such as some noise on the basis of the normal "buzz", such as "bang" or stuffy, it means that the three-way catalytic converter has a problem, and it can be disassembled and checked, otherwise it will be replaced.
There are generally two.
Generally, there is one on the exhaust head section, and then there is one on the middle section of the lower end of the exhaust pipe. >>>More
