How to eliminate the engine fault light (how to solve the problem of the engine fault light?How to adapt to shifting trade policies) Automobile is an indispensable means of transportation in people's daily life. With the continuous progress of science and technology, automobile technology is also more and more advanced.However, it is inevitable that the car will fail during use, and one of the most common problems is that the engine fault light is on. When we are driving a car, we find that the engine fault light is on. What should we do at this time? This article will introduce you how to solve the problem of engine fault light. I. What is the engine fault light? Engine Warning Light is a fault diagnosis function equipped with cars. Once the car engine system fails, the engine fault light will light up to remind the driver that there is a problem with the vehicle. This kind of fault light is generally on the dashboard, which is a yellow or red icon. The driver can determine the severity of the fault according to the color of the fault light and the icon prompts. II. The reason why the engine fault light is on 1. Sensor faulty steamThe car engine system includes multiple sensors, such as air flow meters, oxygen sensors, crankshaft sensors, etc. When one of the sensors fails, the signal received by the engine control unit (ECU) will be interfered, causing the engine fault light to light up. Two. Fuel problems Fuel problems are also a reason why the engine fault light is on, such as problems with the fuel pump and the oil tank lid is not closed correctly. 3. Engine mechanical failure. Engine mechanical failure will also cause the engine failure light to light up. For example, the valve, piston, connecting rod and other components fail. III. How to solve the problem that the engine fault light is on 1. Check the fuel content. If the engine fault light turns on, first check whether the fuel content of the vehicle is sufficient. If the vehicle is not enough fuel, you can refuel and drive away from the emergency lane and turn off the engine.If the engine fault light goes out, it means that the lack of fuel is the root cause of the problem; if the fault light continues to turn on, the next step needs to be carried out. Two. Check the engine cover. Some cars will automatically detect whether the engine cover of the vehicle is closed. If the cover is not closed, the engine fault light will turn on. At this time, it is necessary to check whether the engine cover is closed correctly. If not, close the engine cover and wait for the fault light to turn off automatically. 3. Check the car engine system. If the above two methods cannot solve the problem, it is necessary to check whether the car engine system is faulty. At this time, it is necessary to find a professional vehicle testing center for testing and diagnosis, find out the root cause of the problem and deal with it in time. Four. Clear the fault code. Once the engine fault light turns on, the fault code of the car will be stored in the vehicle control module for the technician to use.If none of the above operations can solve the problem, you can consider emptying the fault code in the car control module. Sometimes the fault code may only be a false alarm, and the engine fault light will also turn off after clearing the fault code. IV. Prevent the engine fault light from turning on 1. Regular maintenance of cars Regular maintenance is very important, which can effectively avoid vehicle failure. For example, replace accessories such as engine oil, air filter and car spark plugs to maintain the stability of the vehicle system and reduce the failure rate. Two. Driving style Car driving habits are also closely related to the engine fault light. Driving behaviors such as high-speed driving and sudden braking are easy to cause some damage to the car. Therefore, drivers should follow the safety driving norms and maintain a slow and steady driving style. 3. Detect the air flow meter. The air flow meter is also a common faulty part of automobile engines.First, if the air flow meter fails, the engine needs to accelerate to work normally, resulting in an increase in fuel consumption. Therefore, the driver needs to check the air flow meter regularly to ensure that the flow meter is in good condition. In summary, the engine fault light is a common problem in the use of cars. If such problems occur, effective solutions should be taken in time. Car owners with conditions can learn basic car troubleshooting skills in order to help themselves in an emergency. However, for some more serious problems, you still need to seek help from the automobile professional maintenance center. In normal use, drivers should also abide by traffic rules and safe driving standards to prevent car breakdowns as much as possible.
