Check engine light 2006 Eddie Bauer Explorer?

Answer 1

A malfunction that is effecting the emission control system has been detected

If the check engine light is flashing on and off that means an engine cylinder misfire has been detected and should be looked after as soon as possible

If the check engine light is on solid , the problem may go away by itself and then the check engine light will go off , just use the vehicle a few times going from a cold start and if the light doesn't go out then take the vehicle in to have it scanned for any trouble code(s) to help diagnose and then repair the problem ( as long as your engine oil pressure is fine and your engine isn't overheating )

It could be anything from your gas cap not being installed correctly , some water in the gas , a sensor etc . ( The first , and only time that I saw my check engine light come on and then go off I just happened to be driving near the dealership and stopped in to have it repaired for almost $ 300 .00 , if I had known better I would have given it a chance to see if if the problem corrected itself , and then if it didn't I would take it in for repair)
