What's wrong with the engine fault light on the dashboard of the car?

The specific analysis is as follows; sensor problems; 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. At this time It will cause the engine fault light to light up.

If there is a problem with the air intake system, there will be poor combustion, and the engine fault light will turn on.

If the car engine fault light is on, it means that there is something wrong with the car engine.There are many reasons why the engine fault light is on, such as poor quality of gasoline, oxygen sensor failure, air flow sensor failure, spark plug carbon accumulation, engine explosion, water temperature sensor damage, etc.

The reasons why the engine fault light is on are generally: poor combustion or poor fuel quality; the inside of the engine cylinder is not clean and there is carbon accumulation; the computer cannot obtain engine data.

What is the reason why the engine fault light on the dashboard

The following are the reasons why the engine fault light is on: poor quality gasoline and does not meet the standard. Not long after the car was refueled, the engine fault light on the dashboard of the car turned on, because poor-quality gasoline was added at a non-standard gas station, resulting in insufficient combustion of oil and gas mixture when the engine was working, and the engine fault light was on. Spark plugs accumulate carbon.

If there is a problem with the air intake system, there will be poor combustion, and the engine fault light will turn on.

The engine fault light on the car dashboard indicates that the engine has failed. There are many reasons for the engine failure, which need to be checked one by one, and it may be due to oxygen transmission.The damage of the sensor may also be due to the damage of the ternary catalyst, the damage of the thermostat, the aging of the ignition coil, etc.

Hello, the fault light of the car engine is on. There are the following reasons: 1 The inside of the engine cylinder is unclean and there is carbon accumulation. After a certain period of use, some carbon accumulation must accumulate inside the engine. These carbon accumulations themselves will cause changes in the engine design parameters, and at the same time, their properties are unstable and accumulate heat, which Some accumulated heat will lead to the engine.

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, and at this time it will Cause the engine fault light to turn on.

The following are the specific reasons why the engine indicator light on the car dashboard is on: sensor failure: including water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged and have poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data. Cause the engine fault light to turn on.

What's wrong with the yellow engine light on the dashboard?

The specific analysis is as follows; sensor problems; 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. At this time It will cause the engine fault light to light up.

The reason why the engine on the vehicle dashboard lights is yellow: water temperature sensor, crankshaft position sensor, air flow sensor, intake temperature sensor, oxygen sensor is damaged, poor contact or signal interruption, resulting in the ECU's inability to accurately obtain engine data. Improper maintenance aggravates the engine operation burden.

The reason why the yellow light of the dashboard engine is on: sensor problems, maintenance problems, oil quality problems, poor combustion of mixed gas, air intake problems.

The reason why the engine lights up yellow: the inside of the engine cylinder is not clean and there is carbon accumulation. After a certain period of time of use, there will definitely be some carbon accumulated inside the engine, which will change the design parameters of the engine itself. At the same time, the nature is unstable and heat will accumulate, resulting in disorderly ignition of the engine, thus causing engine explosion.

The reason why the car dashboard engine turns yellow is sensor problems, oil quality problems, mixed gas combustion, air intake problems, and false faults. The following are the specific reasons and solutions: sensor problems: including water temperature, crankshaft position, empty air flow, intake temperature, oxygen sensor, etc.

Causes and solutions for the yellow light of the car engine

1. The reason why the yellow light of the dashboard engine Sensor problem The sensors mentioned here include water temperature, crankshaft position, air flow, air intake Temperature, oxygen sensors, etc. When these sensors are damaged, the contact is poor or the signal is interrupted, the ECU of the car cannot accurately obtain the data of the engine, which will cause the engine fault light to turn on.

2. What is the reason why the yellow light of the car engine is on? When the car engine is not working normally, but the self-diagnosis system has no fault code output, it is especially necessary to rely on the operator's inspection and judgment to determine the nature of the fault and the part where the fault occurs.

3. The owner finds that the engine fault light suddenly lights up during the driving process. If there is no urgent matter, he needs to find the nearest repair shop to check the cause. Generally speaking, the reasons for the engine fault light to light up are poor quality of gasoline, oxygen sensor failure, spark plug carbon accumulation and water temperature sensor loss. Bad and so on.

4. The fuel quality of the car does not meet the standard. Gasoline is especially important for cars, because without gasoline, cars cannot start. The quality of this gasoline is equally important to cars.When the oil quality is not good, it will lead to insufficient combustion of the engine, resulting in the yellow light of the engine.

5. Reasons and solutions for the yellow light of the engine fault light Oil quality problem: If the oil quality does not meet the standard, it will also lead to insufficient combustion of oil and gas mixture when the engine is working, which will cause engine wear in the long run, and the engine fault light will also turn on.

The reason why the engine fault sign is on, the eight factors why the engine fault light is on

1. The second maintenance problem is that poor engine maintenance is the most common causes engine failure to light up. Reason.

2. If there is a problem with the air intake, if the air filter has not been replaced for a long time,It will cause the air filter to be blocked, thus affecting the normal intake demand of the engine, and the engine fault light will turn on. Solution: Replace a new air filter to solve the problem. It is recommended to replace the air filter every time you maintain it, and the price is not very expensive.

3. The problem of oil products needs to choose the appropriate oil and gasoline according to the characteristics of the engine. There is a problem with the sensor of the vehicle, causing the fault light to turn on. Problems with spark plugs or lines will lead to insufficient combustion of the engine mixture. Maintenance problems, or too much carbon accumulation will also cause insufficient combustion.

4. I: The common reasons are caused by the misalignity of the engine sensor signal, mainly including: lack of maintenance, long-term non-cleaning of the throttle valve, long-term failure to clean the engine carbon accumulation, and some fuel steam will adsorb after carbon accumulation.

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

What is the reason why the car engine fault light is on?

The specific analysis is as follows; sensor problems; 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. At this time It will cause the engine fault light to light up.

As follows: Sensor problems The sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or signal interruption, steamThe ECU of the car cannot accurately obtain the engine data, which will cause the engine fault light to turn on.

The engine fault light of the new car is on, which may be a false alarm from the driving computer. If the vehicle is directly turned off and restarted, the engine fault light can be erased. If the fault light has not been removed after the vehicle restarts, it is a quality problem. At this time, you can go to the 4s store to ask professionals to check it, and you can apply for a replacement if necessary.

Mainly because the oxygen sensor, water temperature sensor, crankshaft position sensor and air flow sensor are damaged, or when the contact is poor, the driving computer of the car cannot obtain the relevant data of the engine, resulting in the engine fault light.
