What Your Check Engine Light Means

Your Check Engine Light (CEL) warns you that your vehicle's computer has found a malfunctioning component in your emission control system. You may see "check engine," "service engine soon," or "check powertrain" displayed on your dashboard.

Don't Ignore Your Check Engine Light

While some issues may be minor, ignoring your check engine light can lead to more serious and costly problems. Getting a diagnostic scan early can save you time and money.
