Modern vehicles, most people have seen check engine light come on while you're driving. And then take a car to auto mechanic shop without knowing what and how serious the problem is as well as how much it will cost to fix it. People hate this light because most likely you will have to spend money to fix the problem and have the light turn off. But you should Nike Air Jordan 13 actually be thankful for the light. A vehicle's computer collect the reading from sensors mounted throughout a car. Then the computer sends a signal to actuators, solenoids, or switches to keep the engine run efficiently. In other words, when sensor's reading is out of specification or when one of actuators is not responding the engine runs less efficiently. You may not feel any change of engine performance. Or you may feel the engine shaking. You may notice that idling is too high. Or you smell gas before a startup. There are over a thousand different problems that the computer can detect. So symptoms are also various. But none of them is good for the engine.
Decades ago, cars were simple. Automotive electric meant only an ignition and a lightening system. There was no computer govern the engine management. There were few actuators, solenoids, switches, and sensors anyway. The engine was running in the same manner under any weather condition. On a cold day, the engine stalled easily. You needed to pull a lever to choke the engine so the engine ran higher until it got warm. There was no fuel injectors that can adjust the fuel volume going to the engine for keeping the best fuel efficiency. If you compare older cars with newer cars, older cars nearly were dumping gas, letting out thick smoke and increasing pollution level.
Auto manufacturers have been making an effort for the better and better fuel economy that leads to a reduction of pollution level. Fuel injector is one of the biggest innovation in an automotive history. Early stage of fuel injection system was kind of rough. It sure needed more adjustments for Nike Air Jordan 5 better engine performance. Auto manufacturers added numbers of components, sensors, solenoids throughout their cars. The development is too fast for people to understand the benefit of new technologies. As a result, people are taking them for granted.
Auto manufacturers didn't just put new components on their vehicles. They also made it possible to let the computer detect the problem when these components are not functioning properly. There are so many components these days. That is why there are over a thousand of obd2 codes. And some of the codes are set by the component that make slight adjustment to the engine. So slight that you might not Nike Air Mags notice the change of engine performance. But the problem exists. Leaving the problem unfixed might be going to be a costly repair.
Please keep it in mind. When check engine light come on, remember a lot of efforts made by the manufacurers in recent decades. I know you are not happy to see the light. But the light tells you the problem at the very beginning of the stage. You should show your appreciation and never ignore the light.
