Car engine light (the meaning and Trade data-driven portfolio managementsolution of the car fault warning light) When driving a car, we often see the prompt of the fault light on the vehicle dashboard. The most common one is the engine light. The engine fault warning light is part of the automotive electronic diagnostic system. It can detect engine faults in time and provide fault information to the driver, so that the driver can take timely action to solve the problem. This article will introduce the significance of car engine lights and how to solve engine problems. What is a car engine light? The car engine light is a kind of warning light, which shows that there is a problem with the engine. When there is a problem with the engine, the automotive electronic control module (ECM) will send a signal to the engine fault light on the dashboard to inform the driver of the problem.The meaning of engine light: Engine fault light is generally composed of an icon, indicating an engine. This light turns on when the vehicle detects a problem with the engine. Usually, the engine fault light will flash or always light up. If the light continues to flash, it means that there is a serious problem with the engine. The longer the light is on, the more serious the problem is. The following are some basic meanings of the engine light indication: 1. Unexpected shutdown If you see a red or yellow engine light, stop in time to check whether the engine has been turned off. If your car accidentally shuts down on the road, it will affect the safety of large vehicles, drivers on the highway and yourself. Two. Oxygen sensor failure When the engine light flashes or lights up consistently, the alarm may be an oxygen sensor failure. The function of the oxygen sensor is to monitor the real state of the discharge and submit the signal to the computer when the discharge exceeds the standard.If the car engine light flashes or lights up consistently, check whether there is a problem with the oxygen sensor of the car. 3. Failure of the engine electronic control block (ECU) When the engine fault light is on, it may be a failure of the engine electronic control block (ECU). This computer controls almost all the functions on the machine and adjusts the working status of the engine according to the sensor signal. If something goes wrong, the whole system will be affected. How to solve the engine problem? When the engine light is on, we need the following inspection and handling methods: 1. Check engine oil. Car oil is one of the necessary parts for engine operation. If there is an abnormality, it can cause serious damage to the engine. If it is mild, the amount of oil is insufficient, and if it is severe, the oil is leaking. Therefore, drivers who often drive and travel must regularly check whether the engine oil is sufficient.Two. Check the engine water temperature. If you find that the engine water temperature is too high or too low, you should stop to check the water tank. If there is a leak or a crack in the water tank, it should be replaced immediately. 3. Check the car battery. If the engine light is on, check whether there is a problem with the car battery. If the battery is faulty, it should be replaced immediately to prevent it from failing. Four. Replace the shock sensor. Sometimes, if the engine light is on, it may be a problem with the shock sensor. The function of the shock sensor is to detect vibration and check whether there is an engine explosion. If you find something wrong with the shock sensor, it's best to ask a professional to replace it. In a word, once the engine fault light turns on, it should be dealt with in time. In order to ensure the safety of yourself and passengers, the car should be sent to the service station for inspection or repair in time.
