Check engine light: A very important info for car-owners

If you own a car and drive it yourself or have a kept a driver, you must know that the check light is quite a nuisance. It does not give out any concrete information as to what has happened. The check light starts blinking and though it is not that difficult to detect the problem yourself, you might have to run to a mechanic which is not exactly a pleasant experience. It can be a major problem that your car has been undergoing and might require quite an amount of expenditure on your part. The only solution, in that case, would be to consult a mechanic and get the light switched off. If you have a scan tool that you use, this will be great.

Some scan tools like Autel, X431, Autoboss, Autohex II can help to identify the fault code.

Here are the main facts that you need to know about check light of a car. So give a reading:

1. The check engine light is also known as the MIL (Malfunction Indicator Lamp) and is situated beneath the steering column of the car and is very convenient to locate. It is basically a signal from the car’s engine’s computer that there is some glitch or obstacle in its smooth functioning. Before 1996, cars were at par with the Environment Protection Agency which looked into the requirements of controlling pollution. But later, cars were loaded with diagnostic trouble codes which made it mandatory that all cars should have a universal connector that will allow them to get access to the necessary information.

2. A check light comes in colors like orange, amber or even yellow, which is actually dependent on the manufacturer. If you see that the light is flashing, it might be indicative of a grave problem, for instance, there might be a misfire that has taken place which has eventually led to the overheating of the catalytic converter.

3. If you are having a problem with your engine check light, there is a scan tool that will come to your rescue. Autohex II is regarded as one of the most powerful scan tools that are available in the market. It is such designed that it will help you solve all your technical problems and will investigate what is the root of the problem regarding the check light in your car. Autohex II will provide you with services that are not provided by the OEM tools. It uses automotive technology and is extremely efficient. It will help you with the services of the pin code as well as online technical support and every possible car problem. It can perform the functions of coding, adaptation as well as key programming and update or even replacement of the ECU.

4. The scanning light may be on if the gas cap has become loose. This problem is quite common among cars and it happens when fuel vapors start to leak out of your cap. This can happen if there is some crack in the cap or it might not have been tightened properly. A loose cap actually sends an error signal to the computer of the car. It reports the issue of the loose cap and the fact that a leak has taken place in the vapor recovery system which is one of the integral aspects of a car’s system of emission. In such situations, you just need to stop the car and tighten the gas cap. You should keep driving and keep an eye on the engine light to see if it has been switched off or not. You can even buy a gas cap at any store of auto parts at a price of $3.

5. The light may also be on due to a variety of reasons like you might need to replace the catalytic converter if you notice that the mileage of your car has reduced. Your oxygen sensor might also need replacement if you see that the gas emissions have increased accompanied by a decrease in the gas mileage. A catalytic converter if needs replacement will cost you around $2000 whereas the replacement of the oxygen sensor will be much cheaper and easier too.

So, if you see your check engine light on the next time, it might be due to the above reasons. So keep an eye on it!
