What Your Check Engine Light Is Actually Telling You

Few dashboard lights cause as much worry as the check engine light. The truth is it can mean anything from a loose gas cap to something that needs real attention, and the only way to know is to read the code.

Solid light vs. flashing light

A steady check engine light means the car has logged an issue you should have looked at soon, but you can usually keep driving carefully. A flashing light is more urgent, often a misfire that can damage your catalytic converter. If it is flashing, ease off and get it looked at right away.

Common causes we see

• A loose or worn gas cap (yes, really)
• A failing oxygen sensor
• Worn spark plugs or ignition coils
• A bad mass airflow sensor
• Catalytic converter problems

Ignoring the light does not make the problem cheaper. A quick diagnostic scan finds the real cause so you are fixing the problem, not guessing. Bring it in and we will tell you straight what is going on.
