When the check engine light illuminates your car's dashboard, it most likely adds a bit of extra stress to your day. A check engine light may come on at a time when you feel as though you car is running fine, and could indicate a problem with a simple solution. 

Many people make the mistake of continuing to drive with an illuminated check engine light for weeks after the light first appears on their dashboard. This can cause a vehicle to fail while out on the road, resulting in the driver becoming stranded. If this happens to you, it will certainly cause more stress than then light coming on in the first place!

In some cases, the check engine light can come on after you fill up your tank, in the event that you did not screw the gas cap back on tight enough. If your check engine light comes on shortly after leaving the gas station, pull over and ensure that the cap has been secured tightly. If this was the reason for the light to come on, then it should turn off after driving a few miles. Other common reasons for the check engine light include the O2 sensor, problems with the catalytic converter, mass airflow sensor, or problems with spark plug wires. However, some problems associated with a check engine light are serious, and can present a dangerous situation if you continue to drive without addressing the problem.

If your check engine light becomes illuminated, your safest bet is to bring your vehicle to a service station as soon as possible. By ignoring this warning light, you put yourself and other drivers at risk, while allowing the problem to become more complex. However by addressing the problem as soon as possible, you can keep your vehicle well maintained and avoid further complications.
