What to Do When Your Check Engine Light Comes On

Alternative Automotive • February 17, 2025

Seeing the check engine light (CEL) pop up can be stressful, but it’s important to understand what it
means.

At Alternative Automotive in Winfield, MO, we’re here to help you figure out what’s happening and get it fixed quickly.

What Does the Light Mean?

The check engine light is part of your car’s diagnostic system, signaling that something isn’t working as it should.

Common causes include:

• Loose or damaged gas cap

• Faulty oxygen sensor

• Engine misfires

• Catalytic converter problems

Is It Safe to Keep Driving?

• Solid Light: Likely a minor issue, but it’s best to get it checked soon to avoid further damage.
• Flashing Light: This signals a serious problem, like a misfire, which can cause major damage if ignored. Stop driving as soon as it’s safe.

Why You Shouldn’t Ignore It

Ignoring the CEL can lead to costly repairs and even safety risks like stalling or reduced handling. The sooner you address it, the less likely it is to turn into a bigger problem.
