Everything You Need to Know About Your Check Engine Light

Dashboard warning lights in a car at Bernard Northtown, showing ABS, parking brake, airbag, and battery alerts.

One of the most common and frustrating problems you’ll encounter as a driver is when your check engine light illuminates. This can cause a lot of concern if you don’t know exactly what caused it, but you can rest assured knowing that it’s usually a simple fix requiring some extra attention. Bernard’s Chrysler Dodge Jeep® RAM explains some common causes.

What Does the Check Engine Light Mean?

Most warning lights are straightforward, alerting you to an issue with a single component or system. The check engine light is different and can signify several things. It most commonly signals a problem with your engine or emission system. While these can sometimes be identified with a store-bought OBD-II scanner, those tools aren’t as precise as the diagnostic equipment used at our Chrysler service center. Furthermore, the average driver doesn’t have the training or experience to identify other problems that may exist in tandem with or be caused by the issues we find.

Solid vs. Flashing

When your check engine light illuminates, it will be completely solid or flashing. This can help you determine just how serious the issue with your vehicle is. Most of the time, the check engine light will appear completely solid – this means that you should address the issue as soon as possible, but the vehicle is likely still safe to drive. A flashing check engine light is much rarer and indicates a serious problem with your car that must be addressed immediately.

Why is My Check Engine Light On?

If the check engine light has turned on, there are several reasons why this may have occurred. Here are the most common issues that come from the check engine light:

  • If you recently filled your gas tank, the gas cap might be loose and produce additional emissions
  • Faulty oxygen sensor
  • Catalytic converter issues
  • You may need a battery replacement if the existing unit isn’t sending enough power to the vehicle’s electrical system and sensors
  • The mass airflow sensor may have become damaged, resulting in decreased fuel efficiency and poor performance
