I'll be just driving down the road and my warning light /! \
periodically comes on and off. It stays on for about a minute then turns off for a while and then comes back on, for no reason. I supose i'll have to pull my engine codes. Does anyone know how to do this w/out having it diagnostic(ed?) so i don't have to pay. I know there is a way. I also saw in a different thread that it that sounded like the the smae thing and they said to check your break fluid - that it was low - well, it wasn't & i topped it off anyway and it still comes on. Any help would be great. Thanks guys

get yourself a small wire and connect the TE1 and E1 ports together and see how many times the engine check light blinks.

Does it happen more often when you are under braking? A lot of people get the light to come on sparatically if your brake fluid is just a liiiiiiiiiiiiiiiiitle bit low. Hope this helps.
