Everyone has experienced it—you turn on your car and it starts up as usual, but an illuminated check engine light makes for an unwelcome surprise. It’s a cause of panic for many drivers and could be a sign of the need for repair. However, you know your engine has a lot of parts, so what does this light refer to? Here, the friendly team of experts from Auto-Tech of Columbia, MO, share their knowledge about this pesky notification—as well as how you should treat it.

One major distinction involving your check engine light can give you a better idea of the severity of a potential problem: is it solid or flashing? A solid check engine light can mean hundreds of different things—from a loose gas cap to a transmission or timing issue. A solid light has one purpose, and that’s to let you know something isn’t quite right. There’s no indication of how severe the problem could be, and it may require a diagnostic test at an auto shop to diagnose the issue.

A flashing check engine light is a different story altogether. If the indicator comes on and begins to flash, it’s imperative you pull your car over to a safe place as soon as possible and turn it off. This flashing often means your engine is misfiring, which, if ignored, can lead to costly catalytic converter repairs or even a fire. If you are more than a few miles from your auto shop, call a tow truck to have your car looked at immediately.

If the light is not flashing and has not been on for a long time, it’s important to have it checked out, but the car is not unsafe to drive. It might even go off on its own after the gas cap is tightened. Some cars also have timed check engine lights based on mileage to let you know it’s time for a tuneup, even if you just had it done. In this case, you’ll need a dealer or mechanic to turn the light off.

The worst thing you can do with a check engine light, flashing or not, is ignore it. An untreated problem will only lead to costly repairs and more time in the shop.
