Check Engine Light Explained

Flashing Check Engine Light

If your check engine light is flashing at you, this indicates a very serious problem–such as a cylinder misfire. This could lead to a very costly and dangerous situation. Bring your vehicle in for your service immediately if your check engine light begins flashing.

Solid Check Engine Light

Even if your check engine light is solid, rather than flashing, your vehicle is still releasing an irregular amount of emissions due to a problem and should be serviced as soon as possible. Problems causing a solid check engine light can range from your engine or another crucial system–any of which can hinder your vehicle’s mileage and performance. At Christian Brothers Automotive, our skilled technicians will diagnose and fix the underlying issue, ensuring your vehicle is safe to drive.

Ignoring the light can lead to more expensive repairs down the road. We use advanced diagnostic tools to accurately pinpoint the cause—and we explain it all in plain English, not tech jargon.
