Car shows engine failure (car engine failure is Hearthstone arenadisplayed on the dashboard) The engine is the heart of the car. If it fails, it will not only affect the performance of the car, but also bring potential danger to the driver. If the car shows engine failure, it is a very serious thing. This article will introduce the possible reasons for seeing the engine fault indicator light on the dashboard, how to deal with this situation, and how to avoid this situation. 1. The reason why the engine fault light may turn on When the engine fault light turns on, the driver may feel panic and at a loss. So, what on earth is going on? ( 1) The engine oil is insufficient or the oil pressure is too low. The engine needs a certain oil pressure to maintain normal operation.If the engine oil is insufficient or the oil pressure is too low, it will lead to insufficient lubrication, increased wear, and even serious cases, it will lead to engine failure. ( 2) Spark plug problem Spark plug is an important part of the ignition system. If there is a problem, the engine may have symptoms such as shaking, poor acceleration, difficulty in starting, etc. If it is ignored, it will lead to serious engine failure. ( 3) Oxygen sensor failure The oxygen sensor is located at the bottom, which can detect the oxygen content in the engine exhaust gas. If there is a problem with the sensor, it will cause the engine performance to decline, and the exhaust gas emissions to exceed the standard, which will lead to engine failure. Two. How to deal with the engine fault light When the driver sees the engine fault light on, the following measures should be taken immediately: (1) Find a safe parking spot immediately. If the engine fault light is on, it is best to stop and then check again.Finding the right parking spot can avoid accidents on busy roads. ( 2) Check the engine fault code. When the engine fault light is displayed in the information center, the correct first step is to check the fault code. Through the fault code, it can be determined which part is faulty, and then carry out relevant processing. ( 3) Go to the overhaul as soon as possible. If the fault cannot be effectively solved, you should go to the regular maintenance site for overhaul in time to avoid more serious problems. 3. Prevent and avoid engine failures. Preventing and avoiding engine failures can not only reduce the occurrence of failures, but also maintain the performance of the car and extend the service life of the car. ( 1) Be sure to pay attention to the maintenance of the car. It is very important to maintain the car. Reasonable replacement of engine oil and filter can reduce the lack of lubrication, and timely replacement of accessories can avoid failure.(2) Pay attention to problems in the driving process. Although engine problems may not be directly caused by the driver, some improper driving behaviors will accelerate the wear and malfunction of the car. Therefore, drivers should pay attention to avoid sudden braking, high-speed driving, excessive acceleration and other behaviors. ( 3) Check and maintain safe driving before driving. Before driving, you should first check the basic conditions of the vehicle, such as tires, brakes, gears, fuel, etc. At the same time, maintaining safe driving can prevent and avoid car accidents and breakdowns. In a word, engine failure is one of the common problems in cars. When the engine fault light comes on, you should stop and check as soon as possible and take corresponding measures in time. In order to avoid this situation, the driver should pay attention to the basic maintenance of the car, avoid improper driving behavior, and maintain safe driving.
