It can be a scary scenario: you’re driving along and your Buick check engine light comes on. What do you do next? Here’s an overview of what to do if your Buick check engine light suddenly illuminates.
First: Stay Calm
The first and most important thing to do if your Buick check engine light suddenly comes on is to stay calm. When safe to do so, pull over so that you can take assess the situation.
Diagnostic
The next step is to determine what could be wrong. Let’s take a look at some common reasons for a check engine light.
- Loose gas cap — If your gas cap is loose, broken, or missing, your check engine light may illuminate.
- Bad oxygen sensor — The air-to-fuel mixture is vital to your engine. If this sensor goes bad, your system’s computer could get the fuel mixture wrong. This can cause serious problems.
- Faulty or failing catalytic converter — On high-mileage vehicles, the catalytic converter might get clogged up. Since this device is crucial to removing carbon monoxide from your vehicle’s system, if it goes bad your car’s fuel economy will suffer.
When you bring your car to our service center, our technicians will run diagnostics to determine why your engine light came on.
