What It Means: Your check engine light may appear for a variety of reasons. Sometimes it is triggered by an open, loose or cracked gas cap, which causes fuel to evaporate. But sometimes it indicates a serious issue, like low oil pressure or overheating! (NOTE: Some car dashboards will display the words “CHECK ENGINE” instead of this symbol.) What To Do: If you haven’t noticed a change in the way the car drives and you don’t notice any unusual sounds or smells, you can continue driving a moderate distance (preferably back home or to your local Virginia Tire & Auto). If the check engine light is red and/or flashing, you should stop driving immediately! In most vehicles, a flashing check engine light signals that you have a major problem that could cause serious damage to your engine if you ignore it. In either case, make sure to get the light checked and the problem repaired as soon as possible.
