Check Engine Light Diagnostics in Yelm, WA
Solving the Mystery Behind the Check Engine Light
What Is It?
If you have ever been concerned about the check engine light in your car, you may question its purpose and reason for being there. The current second-generation (OBD-II) system was created to ensure that your vehicle operates in a way that minimizes environmental impact. Unlike its predecessor, the system has been required on all new vehicles sold in the US since 1996 and uses universal trouble codes so that information is not brand specific. If your car’s check engine light is on, our ASE-certified technicians at Emerald Car Care in Yelm, Washington, can demystify the situation. Employee-owned and staffed by veterans, our shop is located at 10615 Bald Hill Road SE Yelm, WA 98597 (just off 507 down from Tractor Supply and across from the AMPM Convenience Store). We’re open Monday - Thursday 8 am to 6 pm Friday 8 am to 5 pm. While we welcome walk-ins, you can schedule ahead online or by calling us at (360) 458-1421.
What Causes It?
Although the CEL (MIL) is a single lamp, it can be triggered by a number of underlying causes. Our experienced mechanics can use the trouble code along with their own expertise to pinpoint the exact problem. Check engine light issues can range from simple to complex. Many drivers are surprised to learn that a poorly fitting gas cap can breach the sealed fuel system, causing the check engine light to come on. They also dread the thought of a failed catalytic converter, a major repair. Fortunately, that’s a rare occurrence. In reality, the issue is most often somewhere in between. Frequent problems include aged spark plugs, frayed spark plug wires, and ailing sensors (oxygen and mass airflow). Regardless of the cause, we aim to get you back on your way as soon as possible.
