Check Engine Light Diagnostics in Ashland, Virginia

What Does Your Check Engine Light Mean?

Is your check engine light on? We understand it can be a confusing and nerve-wracking situation to be in, but rest assured, Ferber’s Tire & Auto Service is here for you. Serving Ashland, Virginia, we are well-versed in the common causes of the check engine light (CEL) and how it plays an integral role in your vehicle’s overall performance. The check engine light is part of your onboard diagnostics system (OBD-II), which is found in all vehicles manufactured in the United States since 1996. The OBD-II system monitors major components through a network of sensors located throughout your vehicle; parts include the engine, transmission, exhaust, and others. If it detects an issue, it will produce two important elements: a diagnostic trouble code (DTC) that describes the trouble area and the check engine light warning in the dashboard to alert you that service is needed. We can retrieve the DTC, inspect the problem area, and diagnose the exact issue through check engine light diagnostics.

What Causes the Check Engine Light?

Your check engine light can come on for a myriad of reasons. For example, if your gas cap is loose or broken, which can release fuel vapors and provide entry for dirt and grime, it can illuminate. Some reasons are not as simple as that, however. A more serious problem is a misfiring engine, which can result in significant engine damage or an accident. It’s important to remember that severe issues will often present as a flashing check engine light; if you come across this, we suggest pulling over and giving us a call for guidance, as driving may not be safe. Common complications that trigger the CEL include a faulty oxygen sensor, worn or damaged spark plugs, a vacuum leak, a faulty catalytic converter, and a damaged mass airflow sensor. When your check engine light comes on, rest assured that we know what to do. Contact our team today to find out more about check engine light diagnostics!
