Replaced egr valve check engine light is still on - what else could be related to the 401 trouble code on a Ford Windstar?

Funny, you could have had a trained dealership technician, like me, tell you what the problem is for less than you spent on that EGR valve. Penny wise and dollar foolish my friend.
Or simply do some more trouble shooting. Many times the engine code doesn't tell the whole truth on any vehicle. Could be a DPFE sensor or a vac regulator. More that likely the DPFE sensor easy fix. Good Luck

You had your battery replaced in your 98 ford windstar and now your check engine light and abs light is on could this be from replacing the battery and what should you do to turn the lights off?
AnswerThe check engine light could be from changing the battery. Some models will do this saying that there was some loss of power recently. My jeep does this. I would get a hold of a code scanner and check it, because you just wont know what it is until it is read. Autozone will read your computer for free, but I don't think they will reset it. The trouble code has to be erased with a trouble code reader. Also Make sure your emergency brake is also all the way off.AnswerThe key here is that each warning light is trying to tell you 2 different things.
