If its the check engine light its telling you that the computer has seen a problem in the system .......can turn ingnition on and off 3 times and it will flash code on dash like morse code


2 flashes then a pause then 1 flash would be a code 21 ect

your engine maay have maintainennce required . the light can be triggered by mileage
