Getting ready to replace my DPFE sensor after diagnosing my problem here on the forum, but I have one question. Auto Zone has the part for $25, and the Ford dealership has it for $77, is there any reason to buy from the dealership????? If it is the same part and going to last just as long I see no reason not to buy from Auto Zone. Auto Zone claims the part they have is an OEM part, I just cant see not buying thiers unless there is a good reason the Ford part is more expensive. By the way the truck is a 2002 with a 4.6.

 

Quite a few people who have replaced the DPFE have indicated that the autozone (or any other parts store DPFE), may not work as well/long as the 'updated' one from FORD. Buy the one from FORD.

 

The sensor third party venders sell could fail after install or shortly after. Yea, purchase from the dealership to avoid future headaches.

 

Thanks for the quick responses, I guess I will go ahead and buy the ford part.
