What should I do if the engine fault light turns on after refueling

1. Reasons and solutions for the engine fault light of refined oil: Poor quality of gasoline causes the mixed gas to burn in the cylinder Sufficient, causing carbon accumulation. Solution: Replace good quality oil; the engine mileage is too long, and the working characteristics of the spark plug are weakened. Solution: replace the spark plug; mechanical aging of the vehicle.

2. Use fuel additives to clean the entire fuel system. After cleaning the engine, add higher-labeled car gasoline; use good quality fuel additives to improve the cleanliness level of the fuel;The poor quality of gasoline used in the car causes the mixed gas to be insufficiently fueled in the cylinder, resulting in carbon accumulation.

3. The oil is not good. Generally, after a while, it will show that the engine fault light is on due to the filling of poor quality oil. After filling with good quality gasoline, the engine fault light will turn off by itself.

What's wrong with the engine fault light after the car stepped on the accelerator?

1. The specific analysis is as follows; sensor problem; the sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data, which It will cause the engine failure light to turn on.

2. The reason why the engine fault light turns on after stepping on the accelerator is that the combustion state is insufficient. After stepping on the accelerator, the engine needs more fuel and air to meet the acceleration needs. If the combustion state of the engine is insufficient, that is, the mixing ratio of fuel and air is incorrect or the combustion process is incomplete, the engine fault light will turn on.

3. The reason why the engine fault light turns on after stepping on the accelerator is that the engine combustion state is insufficient;The quality of fuel is not good; there is carbon inside the engine cylinder. Solution to the engine fault light: clean the engine; use standard fuel.

Why did the fault light on the instrument light up after adding fuel?

Dealing with the fault light: When the engine fault light is on, you can observe by yourself first. If it is a major failure, the water temperature will rise with the weak shaking of the engine and multiple fault lights on the dashboard will need to stop and wait for professional rescue at this time.

After refueling, if the engine fault light turns on, it is basically caused by fuel problems. Because of the poor quality of the oil, the oxygen sensor will report a fault after the engine burns. It is recommended to go to the 4S store for a detailed inspection so as not to affect the use of the vehicle.

The quality of automobile fuel is not qualified. If the engine fault light on the dashboard of the car lights up shortly after the vehicle is refueled, then it is generally due to the wrong oil addition, poor quality, and non-standard, resulting in insufficient combustion of oil-gas mixture when the engine is working.

It's because the oil is not good. Generally, after a while, it will show that the engine fault light is on due to the filling of poor quality oil. After filling with good quality gasoline, the engine fault light will turn off by itself.

What's wrong with the fuel fault light after refueling? After refueling, the engine fault light may be caused by the wrong number of oil or poor fuel quality.

Langyi, please check the refueling port cover and then the engine fault light is on. What's the situation?

The combustion state of the engine is not good. The poor combustion state of the engine is the main reason for the alarm of the 2022 Volkswagen Touareg fuel tank cap. Due to the inaccurate coordination between the various parts of the engine, the combustion state of the engine is not good, causing the engine indicator light to turn on and go to the relevant 4s store for maintenance.

Engine oxygen sensor is abnormal. The engine oxygen sensor is usually placed near the intake manifold. Due to intense driving or some collisions, the oxygen sensor will be displaced or damaged, resulting in sensor abnormalities and fault light alarms.

Because it has just been adsorbed, the concentration of fuel entering the cylinder is low, which leads to the light. Finally, after stepping on the accelerator, the engine fault light turned on, but it went out after a while. This situation is because the air intake is not smooth. It may be that the air filter is too dirty and the air filter needs to be replaced.

The fault light is on, indicating that the engine has an electronic control failure. It is recommended to go to the repair shop to read the fault code with the decoder, and then repair it according to the prompts of the fault code.

After refueling, the engine fault light is on

1. Engine cylinder shortage: Engine cylinder is the main reason why the engine fault light is on. When the engine is out of cylinder, the car will have abnormal shaking of the body, and the power will be greatly The weakening of. After the engine cylinder is missing, you should go to the repair shop or 4s store to ask professionals to check it to prevent unnecessary trouble in the process of using the car.

2. After adding oil, the engine fault light turns on, indicating that inferior fuel has been added. In the process of engine combustion, due to poor qualityThere are more impurities in the fuel oil, and the combustion rate is low. Some impurities and unburned fuel formed accumulate in the combustion chamber and occupy the combustion chamber space, which leads to the engine failure light on.

3. Tighten the fuel tank cap. If the fuel tank cap is not tightened, it may cause the engine fault light to light up. At this time, just tighten the fuel tank cap. Change the gasoline. It may be that the engine fault light is on because the quality of gasoline is not good enough. Using good quality oil and replacing the original oil can solve this problem. Clean up the accumulated carbon.

4. Poor combustion of the engine is the main reason why the engine fault light is on.

The car has just been refueled, and the engine fault light is on. What's wrong?

The fuel quality of the car is not qualified.If the engine fault light on the dashboard of the car lights up shortly after the vehicle is refueled, then it is generally due to the wrong oil addition, poor quality, and non-standard, resulting in insufficient combustion of oil-gas mixture when the engine is working.

The reasons and solutions for the engine fault light after refueling are as follows: the fuel tank cap is loose: this is a common reason. A loose fuel tank cap will send an incorrect information report to the car computer, and the steam recovery system in the fuel tank fails; so if the gasoline cover is loose, tighten it OK.

Maintenance problems: Failure to maintain on time will cause problems with the car's engine. Oxygen sensor: The oxygen sensor on the car mainly monitors whether the ratio of air and fuel is normal. A problem causes the fault light to turn on. Oil: The failure of the oil does not play the role of lubrication, resulting in engine wear.

The poor combustion state of the engine is the main reason why the engine fault light is on.

After refueling, the engine fault light is on, indicating that inferior fuel is added. In the process of engine combustion, due to the large number of impurities in the inferior fuel and the low combustion rate, some impurities and unburned fuel formed accumulate in the combustion chamber and occupy the combustion chamber space, which leads to the engine failure light.
