What is wrong when engine light turns on?

Answer

The check engine or service engine soon light comes on to alert you that there is or was a problem with the emissions system on your vehicle. If the light comes on steady and stays on, it means that there is a problem and you should have it checked out soon. If it comes on and flashes, it means you will cause damage if you continue driving.
