What Does The Check Engine Light Mean?
The check engine light is part of your vehicle’s onboard diagnostic system (OBD-II). When the system detects a problem affecting engine performance, emissions, fuel delivery, ignition, sensors, or other systems, it stores a trouble code and turns the light on.
The issue may be something minor—or it could indicate a more serious mechanical or electrical problem that requires immediate attention.

-
Loose or faulty gas cap
