That's what I was meaning. There are quite a few aftermarket companies who just rebox old OE parts... wherever he may be buying the replacements from could be still selling the aluminum ones.

Well after replacing this dpfe sensor three times within a week and a new vacum sylinoid my cel still turns on giving me the same 0401 code. I have a new egr and am hesitant to put it in because the old one still seems to open and close when put to the vacum pump. Having said all that it seems like I am not getting but very little suction from the egr vacum line. Can someone tell me what to do next...I need to pass smog so I can get my tags.

I have had the same problem about every 30-50,000 miles. Found this video that explains the symptoms and fixes very well. ; http://www.youtube.com/watch?v=Ev1-kEZL3qQ
Hope it helps!
It appears to be a very common problem mine was a plugged up differential tube some carbon would get sucked up into the tube and cause the P0401 cleaned it with carb cleaner seems to be working much better still using the same DPFE valve. I am driving to Phoenix int eh morning from Lancaster, CA. It should let me know if it fixes the problem.
If not Autozone has a new valve for$30.00 if I have to I'll pick one up on the road.
