It happens to virtually everyone at some point: you’re driving down the road, your vehicle is running smoothly, and suddenly, your “check engine” light comes on. As vehicles have become more technically advanced, computerized components have taken over more and more of your vehicle’s day-to-day operations. As a result, it has become increasingly difficult for everyday people to diagnose a “check engine” problem without advanced tools, such as code scanners.
If you’ve found yourself with a check engine light error, it’s important to get your vehicle to a qualified mechanic as soon as possible. Often times, a check engine light signifies that there is a potential problem with your vehicle’s powertrain and supporting systems. A check engine light may also signify that there is a problem with your vehicle’s exhaust, meaning you could be spewing dangerous pollutants into the air. Then again, it could be something as simple as a loose gas cap.
The problem with the check engine light is that it really doesn’t give you any real indication as to what the exact problem is. Your vehicle’s electronic control systems are so complex and so varied that it would be nearly impossible for there to be a warning light for every potential problem. With that said, as vehicle manufacturers have continued to integrate computer screens and controls into vehicle consoles, the ability to display detailed information has become easier.
If your check engine light comes on, it doesn’t necessarily mean you need to immediately pull off the road. You should, however, get to a mechanic soon. Some vehicles use a graded system of lights to signify dangerous problems over innocuous ones. These systems may use a solid yellow or orange check engine light to show that there is a potential problem that you need to address. As the problem becomes worse, the light may then begin to blink. Finally, if the problem is serious, you may receive a solid or blinking red light. This light may also be accompanied by a chime or beeping sound. If this happens, you should probably pull over, as continuing to drive under this condition could cause serious damage to expensive components.
Fortunately, drivers that experience a check engine light have inexpensive options to have it checked. Many auto parts stores will perform a system scan for free, which will then generate a trouble code. This trouble code will allow you to know exactly what’s wrong, allowing you to decide whether it’s something you need to fix right now, or if it’s something that can wait.
