Bob Howard Buick GMC welcomes you to discover why your Buick GMC check engine light is illuminated.
The check engine light warns owners of potential engine problems or complete failure. Your car’s check engine warning light might come on due to many reasons. It may be anything from a simple sensor failure, an alert to perform maintenance, or even warning drivers of potentially significant issues that might contribute to engine failure. So, just because the check engine light turns on, it may not be a complete catastrophe. However, when your check engine warning light does come on, you should bring it to us for a thorough diagnostic inspection. Even if nothing acts broken, getting it inspected can mean the difference between a simple fix and having to replace the engine.
Something as basic as not replacing the gas cap or not replacing it correctly can trigger a check engine warning light. A car’s gas cap will probably need to be changed during your ownership. After 50k miles, you should consider replacing a gas cap. We recommend genuine replacement parts from the manufacturer if it is time to replace your gas cap. Using parts from DIY stores can work in a pinch, but nothing beats original parts from the manufacturer.
Several sensors give info to your engine to help it run efficiently. However, missing sensor readings from components like the MAF sensor or the oxygen sensors can trigger a check engine warning light to come on. If the vehicle seems normal, a broken oxygen sensor is the most likely reason. This may mean that your vehicle is actually running normally, but because the engine isn’t receiving the data, it triggers a warning. Even if your vehicle feels normal, you should get your car checked out immediately to rule out more significant problems.
Spark plugs are vital to the performance of your vehicle’s engine. As the name implies, they provide a tiny spark of electricity, which then ignites the gas and causes your engine to run. Spark plugs demand very precise measurements for optimal effectiveness, and if the spark plug gap is incorrect, it could possibly cause a check engine warning light. Symptoms of faulty spark plugs include lower fuel economy, slower acceleration, and your engine just doesn’t run smoothly.
