The Customs data verification servicesengine fault light of the new car is on. When the engine fault indicator light of your new car is on, this is a worrying thing. This usually means that your car may have problems and needs to be overhauled in time to avoid more serious damage.In this article, we will discuss the reasons why the engine fault indicator light of the new car is on, how to deal with it and how to prevent this situation. 1. What is the engine fault indicator light? The engine fault indicator light of a new car, also known as the "Check Engine" light, is a yellow indicator light that is usually located on the dashboard of the vehicle. Its function is to provide the driver with warning information about the engine condition by monitoring the engine operation of the vehicle. When the vehicle detects a problem with the engine or emission system, this indicator light will light up. This may mean that some parts of the engine are faulty, such as oxygen sensors, throttle valves, ignition systems, accelerator pedals, etc. In addition, the intelligent computer system can also detect problems by detecting the automobile emission control system. Two. What is the reason?There may be many reasons why the engine fault indicator light turns on. Below we list some common problems: (1) Oxygen sensor failure: Oxygen sensor is an important part of the engine emission system. Its main function is to measure the oxygen content in the engine gas and send the information to the car computer system. If the oxygen sensor fails, the engine fault light will turn on. ( 2) Valve failure: The valve of the engine controls the air and fuel in the combustion chamber in the cylinder. If there is a problem with the valve, such as loose closure or inability to open, it will cause oil leakage and engine fault light to light up. ( 3) Fuel steam system: Fuel steam system plays an important role in automobile fuel system. Its function is to capture and store the oil and gas evaporated from the fuel tank and fuel system to reduce emissions.If there is a leak or other problem in the system, the engine fault light will also turn on. In addition to the reasons listed above, there are many other problems that may cause the engine fault indicator light to light up. 3. How to deal with it? Don't panic or be indifferent when the engine fault indicator light is on. Here are a few basic steps: (1) Parking: If the vehicle is running normally after the lights are on, you can stop temporarily, turn off the engine, and then restart the vehicle to check whether the lights disappear. If the lamp goes out, it may not be the real problem. If the problem persists, it needs to be repaired in time. ( 2) Check the fuel tank cover: Sometimes the reason why the engine fault indicator light turns on is that the fuel tank cover is loose, resulting in pressure leakage. Check the seal of the fuel tank cover, and then turn the sealing rod to make sure that it is tightly fixed to the fuel tank.(3) Check your own ability: If you are a mechanic with relevant skills, you can check some basic parts of the engine, such as oxygen sensors, air filters, ignition systems, etc. If you don't have relevant skills, you'd better send the vehicle to a professional maintenance service station for inspection. In a word, once the engine fault indicator light is found, timely measures need to be taken. Don't ignore this problem, because it may affect the performance and emissions of the vehicle, leading to more serious problems. Four. How to prevent it? Although engine failure cannot be completely avoided, we can take some measures to reduce the possibility of failure. Here are some useful suggestions: (1) Regular vehicle maintenance: Regular inspection and replacement of the vehicle's oil, oil filter, air filter, spark plug, etc. can reduce the possibility of engine failure.(2) Pay attention to the quality of oil: Choosing good oil and complying with the normal replacement cycle can extend the life of the vehicle and reduce the possibility of fuel consumption and engine failure. ( 3) Don't be in a hurry to drive: Don't over-accelerate, drive at high speed or carry goods that exceed the carrying capacity, which may cause damage to the engine and lead to engine failure. In a word, when the engine fault indicator light lights up, it needs to be dealt with in time. Regular maintenance of the vehicle, paying attention to the quality of oil, and not rushing to drive can reduce the possibility of engine failure. Most importantly, if you don't know how to deal with this situation, you'd better send the car to a professional maintenance service station for inspection.
