When we talk about check engine light or CEL then it is actually the warning indicator. It means that it has been determined by the computer of your vehicle that any system or some component of the vehicle is not in operation properly. As soon as the light gets on, the module of engine control stores a couple of “diagnostic trouble codes”. Even if engine module turns off the light the DTCs still remain. For addressing a problem of check engine light, retrieval of the DTCs is performed and some reasonable troubleshooting information is followed for finding the problem.
Some of the most common scenarios are given here that can be experienced by someone with the Check Engine Light.
One of the common things is that the light flickers and gets on and off. If your “Check Engine Light” gets on when you are in city and it gets off on freeway, it may be due to some fault in driving conditions in city. In such a case you will have to pay some attention to any difference in the driving or the running of the car when illumination is generated in Check Engine Light. If you feel any kind of change in the performance of the vehicle then you should drive your vehicle as less as you can and get it checked from some professional the soonest. If you don’t feel any kind of change in the performance then you can easily drive it to your destination but you should get it inspected as soon as you can.
Another common condition is that the light just gets on and keeps its state. If there is such constant illumination in your Check Engine Light and you don’t notice any apparent performance problems then certainly there is some permanent fault in your vehicle’s emission-control system. When such a fault occurs, computer controlling vehicle’s emission system often runs the backup program and it persists as soon as the fault is there. The vehicle should be serviced the soonest it is possible.
Another common scenario is the permanent illumination in the Check Engine Light and some performance problems are there. This depicts that there is some serious problem in some crucial component of the emission control and the engine management system. It often involves some system or component that is required by the vehicle for running. So as it is critical, therefore you should drive as less as you can. In most cases, it is not safe to drive the vehicle in such a state. The vehicle may stop at any time. It will be the best approach to pull it over to the safe place and get it inspected.
