How did my car exhaust the intake and oil circuit carbon deposits, and the engine failure bulb lit 2

Carbon build-up in the engine is hard to avoid, it's only a matter of time. To solve the problem of carbon deposition, we must first understand the causes of carbon deposition. When the owner turns off the engine, there is always the gasoline fired from the cylinder, and after the gasoline volatilization left in the cylinder block, valve and combustion chamber, the remaining gum and paraffin wax are thicker and thicker, and carbon deposits are formed after hardening after repeated heating.

As for how to maintain it to reduce carbon deposits.

1. Use clean gasoline, the more clean the gasoline, the less glue and paraffin, and it is also a desirable practice to add gasoline detergent.

2. Cultivate good driving habits, try not to drive at low speed for a long time, and do not shift gears at low speed, in this case, insufficient gasoline combustion will occur, and carbon deposits will be easily generated.

3. Regular cleaning and maintenance, regular maintenance on time, and regular cleaning of the air duct, valve, oil circuit and other parts of the air intake system that are prone to carbon deposits.

The engine fault light is generally a problem with the sensor and body electrical equipment, and it is necessary to use the computer to read the fault code and repair it according to the specific fault code.

First of all, we must look at the fault code, generally throttle valve with throttle cleaning agent, intake and exhaust valve with valve self-quiet, that is, high speed, high speed, uniform speed, that is, commonly known as pull high-speed self-quiet.

The sensor signal has changed, so let's use the computer to rematch it.

The first is to reduce the engine power, that is, to make the power output uneven and gradually decayed, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden. The third is the difficulty of cold start, that is, the difficulty of ignition, and it is not easy to get on the car.

Finally, serious carbon deposition in the combustion chamber will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, thus seriously affecting the safety of the car. Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment. The specific principle is that if you do not pay attention to the oil and driving habits for a long time, the wax and gum in the gasoline will accumulate thicker and thicker, and carbon deposits will be formed when they harden after repeated heating.

If the engine burns oil, or if the gasoline is of poor quality and has more impurities, the valve carbon deposits are more serious and form faster. Because the structure of carbon deposition is similar to that of a sponge, when the valve forms carbon deposition, a part of the fuel injected into the cylinder will be adsorbed, which makes the concentration of the mixture that really enters the cylinder thinner, resulting in poor engine work, and abnormal phenomena such as difficult starting, unstable idling, poor acceleration, urgent refueling and tempering, excessive exhaust gas, and increased fuel consumption. If it is serious, it will cause the valve to be closed loosely, so that there is no cylinder pressure in the cylinder and it will not work completely, and even adhere to the valve to prevent it from returning.

At this point, the valve and piston will interfere with the movement, which will eventually damage the engine.

(1) After the engine fault light is on, the car cannot be started. This may be caused by the failure of the ignition part or fuel pump, at which point the vehicle will definitely not start, so you can only call a tow service to tow the vehicle to a repair point or 4S shop for repair.

2) Although the engine fault light is on, it can still drive, and there is nothing abnormal in driving. At this time, either a sensor is faulty, or the vehicle has a false fault, and it is impossible to determine what caused the fault light to turn on, so it is better to go to the nearest maintenance point as soon as possible to check and repair.

3) The engine fault light is on, and the vehicle can be driven, but there will be shaking, acceleration weakness, etc. In this case, it is not recommended to drive the vehicle again, although the vehicle can still be driven, but continuing to drive will lead to increased failure, resulting in engine damage, and in severe cases, it will cause other failures. So don't continue driving, stop the car and call ** and wait for help.

Summary. Hello, happy to answer your <>

The reason why the engine light is lit with carbon deposition cleaning agent is 1Engine Control Module Failure: The engine control module senses that there is a problem with some system, the discharge system, the ignition system, and the fuel system, and it triggers the engine fault light.

Carbon deposition cleaners can cause the control module to perceive a problem, causing the engine fault light to come on. 2.Blocked fuel nozzles and faulty oxygen sensors.

The above is the reason why the engine light is on with carbon deposition cleaning agent.

With the addition of carbon deposition cleaner, the engine light is on.

Hello, the number of lines is happy to answer your <>

The above is the reason why the engine light is lit with the carbon deposition cleaning gear sail.

So how to eliminate the fault light, the repairman eliminated it twice, and it still lit up the failure.

Are there any fault codes now? Is there any reason for the shaking?

The fault light is on, the power drops, and the idle speed shakes.

It is the carbon deposits that adhere to the spark plug and affect the quality of the spark. Not even a jumper.

So how to eliminate the faulty lamp.

The spark plug was also replaced, it didn't work.

Kiss <>

Clean the spark plugs.

Changed. Kiss <>

What is the fault code.

Engine failure lights.

Kiss <>

What is the fault code found out by the computer?

Kiss <>

It is caused by poor combustion of the car's gas mixture.

Extension: Fault Code Definition: The fault code describes the dust fault type of the component, and consists of the fault level bit and the fault description bit.

The first-level failure occurs and continues until it disappears after receiving the non-return Qin enable command. Other failures are held for 1 second after the failure disappears.

Can carbon deposits cause engine failure lights to come on? Can carbon deposits cause engine failure lights to come on? There are many reasons why the engine fault indicator light is on.

Carbon deposits do not directly cause the engine failure light to come on, but the engine failure light does come on because carbon deposits can cause problems in other areas. If there is a problem with the oxygen sensor and three-way catalyst, the engine fault indicator will illuminate. Excessive carbon deposition and long carbon deposition time are one of the causes of problems with oxygen sensors and three-way catalytic converters.

Therefore, after the parts that are lit by the engine fault indicator light and the fault indicator light are repaired, if the engine does not clean up the carbon deposits, the carbon deposits of the engine can also be cleaned up. @2019

Summary. Hello, I am glad to answer your car master exclusive technician attentively and sincerely answer your car questions, find solutions and methods for you to ask questions, when the vehicle particle trap fault light is on, there are two ways to eliminate the prompt.

First, the dust and ash substances in the particle trap are eliminated by running at high speed, which has certain requirements for driving road conditions, and it is necessary to drive on elevated roads or highways.

Second, the dust and ash of the particle trap can be eliminated through the workshop regeneration function, which can be effectively eliminated in this way. It takes about half an hour. I hope I have been helpful to you, and if you have any other questions, you can continue to ask questions.

The engine fault light is not necessarily a carbon deposit problem, with the addition of inferior gasoline, the oxygen sensor, water temperature sensor, crankshaft position, air flow, inlet temperature and other sensors are faulty, and the intake air is blocked, etc.

Go to the repair shop and read the fault code.

1. The most common is to disassemble the throttle, clean the front and back of the throttle with a carburetor, and dry it with a cotton cloth. Generally, it is recommended to clean the lower throttle for a year or 20,000 kilometers, of course, different models will have different cleaning cycles, we can do it according to the maintenance manual.

2. Carbon deposition cleaning inside the engine, we can do it before we want to change the oil to a new one. Open the oil cap, add detergent, mix with old oil, and idle for about 10 minutes. You can buy the detergent by yourself, the operation is very simple, and you can operate it yourself.

3. To clean the air intake system, buy a bottle of air intake system cleaner, pour it into the liquid storage tank of the special cleaning equipment, connect it to the air intake system, and use the vacuum to suck the detergent into the air intake road to achieve the purpose of cleaning. Cleaning the carbon deposits in the intake system mainly refers to cleaning the carbon deposits inside the intake tract and intake manifold. The purpose is to remove carbon deposits from the intake system, increase intake flow and speed, and reduce engine shake and idle instability.

Restart the power door: Turn off the power to the vehicle so that the vehicle is completely de-energized, and then turn the power back on.

Perform fault code scanning: Use the vehicle diagnostics to scan the ECU to see which fault codes have been stored.
