The fault light is yellow, and the fault yellow light is on

First of all, the first one is our oil failure lamp, which is the oil pot lamp in the shape of Aladdin's magic lamp. The oil light is on, indicating that the pressure of our oil is abnormal, and there may be a lack of oil in the engine, which is equivalent to the blood of the engine.

Once we find that the oil lamp is on, we should pay attention to check two places. First of all, if the yellow light is on, listen carefully to whether the sound of the engine is different from before, whether there is a particularly loud sound, to roughly judge whether the oil light is on and does not affect the engine. In addition, if the oil lamp is red light, it means that there is a shortage of oil, at this time, you should immediately pull over, turn off the ignition, and check the oil height of the oil dipstick.

In general, the yellow light is a warning, the problem is not big, we can insist on driving to the repair shop, add some oil, maintenance and check. But if the red light is on, it means that it is already a big fault, if you add oil, it still can't turn on the red light, then it is best to find a tow truck and call a rescue. We can call the insurance company, and generally there will be this free towing service.

The second is the engine failure light, which is the one on the dashboard that kind of resembles a Super Mario pipe. If we drive normally and maintain it regularly, there will generally be no major problems with the engine.

Once the fault light of the engine turns yellow, it means that there is a problem with the working state of the engine, and most of the time the combustion state is not good. This is because there is an oxygen sensor in the engine that monitors the status of the combustion chamber at all times.

The engine needs to be injected with fuel and suction air to start combustion, for example, if the air intake is less due to the air filter blockage, it may also turn on the yellow light. It is also possible that the quality of the oil you add is too poor, as well as the carbon deposits in the engine, and the oil circuit is blocked.

Either way, it may affect the power output of our car. If the engine light is always on, you should also find a 4S shop as soon as possible and check it as soon as possible.

The car's yellow light is faulty**:1. The engine fault light is displayed, indicating that there is a problem with the engine.

2. The car steering power failure lamp, the car steering power is problematic.

3. Engine power control system.

4. The bulb damage indicator light.

5. Clean the liquid level and low fault lamp.

6. Anti-lock braking system lamp.

7. Body stability control system.

8. Tire pressure low warning light.

9. Fuel level low warning light.

A yellow indicator is a warning light, which indicates that a system is abnormal. When the fault light of the yellow exclamation mark of the car is on, it means that the tire pressure is low or the tire pressure system is faulty, and it is recommended to go to the 4S store to check the tire pressure.

1. The danger of excessive tire pressure.

a. The friction and adhesion of the tire will be reduced, which will affect the braking effect.

b. Cause the steering wheel to vibrate and deviate, so that the comfort of driving is reduced.

c. Accelerate the local wear of the tread pattern of the tire, so that the life of the tire is lowered.

d. The vibration of the body becomes larger, which will indirectly affect the life of other parts.

e. The tire cord will be subjected to excessive stretch deformation, and the elasticity of the carcass will decrease, so that the load of the car will increase while driving.

f, and make the rolling resistance decrease. When encountering sharp objects such as nails and glass on the road, it is easy to penetrate into the tire, and the impact will produce internal cracks and bursts, resulting in a puncture.

Second, the danger of low tire pressure.

a. The coefficient of friction with the road surface will increase, and the fuel consumption will increase.

b. The steering wheel is very heavy, easy to deviate and other factors that are not conducive to driving safety.

c. Increase the amount of exercise of all parts of the tire, and cause abnormal heating of the tire due to excessive rolling.

d. The function of the cord and rubber is reduced, causing delamination or excessive friction between the cord and the rim, resulting in damage and abnormal wear of the bead.

e. The friction between the tire and the ground increases exponentially, the tire temperature rises sharply, the tire becomes softer, and the strength decreases sharply. If the vehicle is driving at high speeds, it may cause a flat tire.

f. The tire pressure is too low to increase the deformation of the carcass, and the sidewall is prone to cracks, and at the same time produces flexural motion, resulting in excessive heating, promoting rubber aging, cord fatigue, and cord breakage, which will also increase the tire grounding area and accelerate the wear of the shoulder.

Automobile fault lights are roughly divided into three types: indication, prompt, and warning.

Indication class: It is used to describe some basic conditions of the vehicle, indicating the current working state of the vehicle, and is convenient for understanding the functions and states of the vehicle. (e.g. light system indicator, water temperature indicator, fuel level indicator).

It needs to have a faulty indicator to explain.

Summary. Dear, hello, the fault huang light is on is like this 1There are many reasons for the engine failure light to turn on, including high engine temperature, lack of cylinder in the engine, engine knocking, serious carbon deposition in the engine, poor fuel quality, etc.

2. After the fault light is on, there are two situations: one is that although the light is on, there is no abnormal feeling when driving, and everything is normal such as acceleration and braking, then the car can be carried out normally. It may be that a sensor has failed, or some external conditions interfere, or this fault does not affect the vehicle at all, but may have a certain impact on emissions.

In this case, you can continue to drive for the time being, and take the time to go to the 4S store for testing.

Dear, hello, the fault huang light is so coarse 1There are many causes of the engine failure light, including high engine temperature, lack of cylinder in the engine, engine knocking, serious carbon deposition in the engine, poor fuel quality, etc. 2. There are two situations after the fault light is on:

First, although the lights are on, there is no abnormal feeling when driving, and everything is normal when accelerating and braking the car, so the car can be carried out normally. It may be that a sensor has failed, or some external conditions interfere, or this fault does not affect the vehicle at all, but may have a certain impact on emissions. In this case, you can continue to drive for the time being, and take the time to go to the 4S store for testing.

Data Expansion: Fault Huang Lamp is 1Oxygen Xiangjin sensor failure.

If the oxygen sensor is damaged or the sensor plug is damaged or loose, it will cause the reassignment mixture to be too thin or too thick, which will cause the fault light to turn on. 2.Gasoline is of poor quality and substandard.

Generally, it is because of the addition of poor quality gasoline at non-standard gas stations, resulting in insufficient combustion of oil-gas mixture when the engine is working. At this time, the car dashboard will light up. 3.

Spark plug carbon deposit. Excessive carbon deposition will lead to the reverse breakdown of the ignition coil, which in turn will lead to the failure of the ignition coil, resulting in poor ignition and incomplete combustion. At this point, the fault light will also turn on.

If the yellow light of the engine on the dashboard is on, if it is lit up and then turned off during the car self-inspection, it is possible to drive, if the yellow light of the engine fault is still on after starting the car, do not continue driving.

There are two situations when the engine yellow light on the car dashboard is on, the first is when we turn on the power of the car, the vehicle will carry out a self-test, at this time, not only the engine yellow light will be on, but other fault lights will also be lit together, and then they will be extinguished together, which is a normal phenomenon. The second is that after the car starts, the yellow light of the engine fault is still on, which is an abnormal phenomenon that the ECU is reminding you that the engine has a key rental cleaning fault.

Inspect the vehicle

If in the process of driving the vehicle, if you find that the yellow light of the engine is on, the car can continue to drive, but it is not recommended to continue to drive, and you avoid causing potential safety hazards, so once you find that the yellow light of the engine is on, you need to go to the 4S shop in time to check the maintenance of the car, and after the fault of the engine is lifted, you can continue to use the vehicle.

The engine fault light is on, the vehicle can be driven, but there are symptoms such as severe shaking and acceleration weakness, don't take the courage to try your luck in the face of this situation, continuing to drive may increase the failure, damage the engine, or cause other failures, so it is not recommended to continue to write before you should call for help** and wait for support.

If your car fault light is on, then you should take the following actions immediately:

Understand the fault lamp: understand the meaning of the fault lamp, and determine the degree of the fault to determine the severity of the fault. You can check the car manual or ask a service professional.

Check the oil level: Check whether the oil level is normal. If the oil level is too low, ** full of oil.

Check the fuel system: Check the fuel system for leaks or faults.

Check the battery: Check the battery for faults and replace the battery if needed.

Check the ignition system: Check the ignition system for malfunctions.

Check the cooling system: Check whether the cooling system is faulty.

Take your vehicle to a workshop: If you're not familiar with your vehicle's systems or can't resolve a breakdown, take your vehicle to a professional workshop.

If you're not sure what it means when your vehicle breakdown light is on, or if you're not confident in resolving your vehicle's fault, it's important to have your vehicle inspected by a professional automotive technician.

Pacific Automobile Network] engine yellow light in different brands of models called different, some called engine fault lights, some called exhaust system fault lights, but the graphic identity is very unified. This light is on to indicate a malfunction in the engine's exhaust monitoring system, commonly known as three-way catalytic converter poisoning.

The engine fault light is a problem that every car owner can not ignore, which is directly related to engine life and driving safety. The engine failure light is usually caused by the following reasons.

1. The quality of gasoline is poor, and it is estimated that most car owners have this experience, and soon after the car is refueled, the engine failure light is lit on the car dashboard; This is generally due to the addition of poor quality gasoline at non-standard gas stations, resulting in insufficient combustion of the oil-gas mixture and the engine fault light when the engine is working. This will not affect driving safety, but it will be more or less harmful to the engine.

2. Oxygen sensor failure: Now there are two oxygen sensors installed on the car, one before and one before and after the three-way catalytic converter. The function of the front oxygen sensor is to detect the air-fuel ratio of the engine under different working conditions, while the ECU computer adjusts the fuel injection amount and calculates the ignition time according to this signal. The rear is mainly to detect the working of the three-way catalytic converter!

Therefore, if the oxygen sensor is damaged or the sensor plug is damaged or loose, the mixture will be too thin or too thick, which will cause the fault light to turn on.

In fact, the oxygen sensor is a fairly durable component that can last for 3 years or more as long as the fuel quality is passable. Therefore, the barrier light of the old laughing hall of the new car is on, you may wish to check whether the oxygen sensor plug is loose.

3. Air flow sensor failureThe air flow sensor is also known as the air flow meter, which detects the amount of air inhaled and converts it into an electrical signal and transmits it to the ECU of the electronic control unit. If the air flow sensor or wiring fails, the ECU will not get the correct intake volume signal and will not be able to control the normal fuel volume, resulting in the mixture being too thin or too thick and the engine will not work properly.

Although the air flow sensor is not malfunctioning to cause the engine to fail to start, phenomena such as unstable idling, poor acceleration, flashback of the intake pipe, and black smoke from the exhaust pipe are still highly likely.

There are three reasons why the engine fault light is yellow: sensor problems, maintenance problems, and poor combustion of the gas mixture.

1. Sensor problem: The sensor here includes 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, which will cause the engine fault light to turn on.

2. Maintenance problems: Poor engine maintenance is the most common cause of engine failure. Vehicles have a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, it will increase the burden of engine operation, resulting in the failure lights to warn.

3. Poor combustion of mixture: spark plug failure, ignition coil failure, fuel pump failure, oil circuit blockage, etc. of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture can lead to engine carbon deposits or knocking, which are eventually detected by the engine's oxygen sensor and reported to the ECU, causing a fault light to light up as a warning.

The importance of engine failure lights

The engine fault light is a very important indicator light on the car, which can remind the driver to find the engine fault in time and take timely maintenance measures to protect the safety of the engine and reduce the loss and safety caused by untimely maintenance.

The display of the engine fault light and its importance provide an important reference for the driver, and the driver should keep in mind that the engine fault should be dealt with in time to protect the safety of the engine and reduce maintenance losses and safety hazards.
