A vehicle’s check engine light might turn on for a variety of reasons. Some of these reasons are easy fixes and nothing to worry about, like a loose gas cap that needs replacing. However, this light could also be indicative of a much more serious problem that can permanently damage your engine. Always consult your owner’s manual to try to self-diagnose the issue. Many check engine lights blink or change color to relay the severity of the issue. If you can’t get the light to turn off or you’re worried something could be seriously wrong, contact Sample Shop for a check engine light diagnosis.
