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.
