It’s natural to feel uneasy when the check engine light comes on in your car. Even if the vehicle seems to be running normally, it’s important to figure out why the light is on. Both minimal issues with a sensor and serious problems that require engine repair can activate the light. Here’s what you need to know before getting back on the road.

What Causes the Check Engine Light to Turn On?

Modern cars rely on onboard computers to work properly. These handle fundamental functions and record important data about performance. 

When the check engine light comes on, your car’s computer has come across an unusual symptom that could indicate a problem with the vehicle. It will store the error code, which an auto mechanic will be able to identify with a diagnostic device. The most common error codes point to faulty ignition coils, spark plugs, oxygen sensors, and catalytic converters.

What Should You Do Next?

In most vehicles, the check engine light will flash or turn red for issues that require immediate attention, so you should promptly take your car into a shop for an inspection.

There are a few steps you can take to determine if engine repair is required for your vehicle. First, see if there are any other indicators of an engine malfunction, such as unusual sounds or changes in steering.  

A loose gas cap can cause the light to come on in some models, so try tightening yours first. If that doesn’t help, visit an auto shop.
