What does a Check Engine Light mean?

In short, it means pay attention. Your vehicle is sensing that something wrong might be increasing your car’s emissions.

Look, we all know the drill. The check engine warning light comes on, and it feels generic, and a little bit goofy. It looks like a graphic on a kid’s toy, and it doesn’t really feel urgent.

So, you ignore the check engine light. And you keep ignoring it, thinking it will go away.

Guess what? Your engine won’t repair itself. Meaning, the check engine light is not going to go away if you keep ignoring it. You can cross your fingers all you want, but it’s there, until the issue is resolved by getting a diagnostic.

The check engine warning light is kind of a catch all sensor for everything that can go wrong with your car. A large number of issues can ultimately result in the light illuminating. You might think that vagueness makes the light sensor less important. You’re wrong. The vagueness provides all the more reason to diagnose the issue. 

That said, sometimes the issue causing the check engine light is minor. In fact, the check engine light can even come on if your gas cap isn’t screwed on properly after you fill up. So, uhh…check the gas cap before you freak out.

Ultimately, the check engine light is like a grim grab bag at a party. You need to diagnose it because it could be absolutely anything. While a lot of the issues a mechanic might diagnose are minor,  some – such as transmission problems, faulty oxygen sensors or catalytic converter, engine mechanical issues, and computer malfunctions – are a bit more serious. The check engine light is designed to pop on for anything that leads to increased vehicle emission through your exhaust system (issues like an overheating engine, catalytic converter, failing oxygen sensor or slipping transmission can lead to increased emissions). 

So stop doing that thing you do where you ignore the check engine light and get an OBDII diagnostic today. Your wallet and engine will thank you later down the road.

How to spot a Check Engine Light

Warning lights are illuminated

Well, that was pretty straightforward, wasn’t it? I’m hoping you could have gotten there on your own. But it’s important to pay attention to more than just your check engine light. Oftentimes, mechanical issues will cause multiple lights to come on. If, say, your charging light is on and your check engine light is on, then you probably don’t have two problems. You probably just have an issue with your charging system. Regardless, we recommend that you get a diagnostic for the check engine light as well as any other lights your vehicle's engine sensors are picking up on .

How urgent is a Check Engine Light?

Did you miss that whole spiel earlier? It’s important to get a diagnostic for a check engine light. Ignore the check engine warning light at your own risk. It could be a gas cap, it could also be a transmission, engine, or electronics issue, that, if ignored, leads to serious damage and a huge dent in your wallet. Not to mention, it could be a serious safety issue.

Ignoring your check engine light, and not getting diagnostic, is like ignoring your parents. It might seem cool, but eventually you, and your engine, will realize it’s a really bad idea.
