The check engine light came on several weeks ago. I immediately took the
car in and P0401 code came up (insufficient EGR flow). The DPFE checked
out bad and a new one was ordered which took 3 weeks to get!!!
Valve replaced but tech could not get the light to stay out. Same code
kept coming back. I went on the internet and found that it could have
plugged ports caused by carbon buildup. Also found the info on
disconnecting the battery to recognize the new part.....The car was at the
shop for a week. I picked it up Friday, drove out of the lot and the light
came back on. Since the shop was closing as I left and it's a holiday
weekend I stopped by an Autozone Saturday morning where they let me use the
code reader thingy to be sure I didn't have ANOTHER problem and the same
code comes up. Will the same code come up if the solenoid is bad? I need
to get this car smogged within the next week and I need some help.
I am sure that the good folks on this newsgroup will help you out. But there
are numerous different EGR hookups, and some maladies are specific to
particular engines and model years. So please give us a bit more to chew on:
what vehicle is it, year, mileage, engine size? Perhaps also some
driveability problems that you observed. You know, the basics...
car in and P0401 code came up (insufficient EGR flow).
The car with the Code P0401 is a 1996 Ford Taurus LX. Except for that darm
"service engine soon" light, you would never know there was anything wrong
with the car. I am sensitive to any new noise and in fact asked about a
very intermittant noise I heard while I had it in for this problem. Turned
out to be the water pump which itself may not have been bad but a bolt had
sheared off and another was ready to go. The car just turned 84,ooo miles
and I had hoped to drive it for many more years. If I can't get this
problem solved, it's just junk.

I am wondering if that might be an emissions warranty type repair...
Somewhere around 1996 they added a 100,000 miles / 10-yesr (I think) to the
emissions systems and that code would come from enissions - have you checked
with a dealer?
