P1401 DPFE Sensor??
Hey guys, I just recently pulled the P1401 code on my truck and need to get the sensor fixed before my next emissions test. I called the dealer and they quoted me $116 for the new sensor. Is there any other place that I could buy this sensor without hollowing out my wallet?

I had to replace mine on my 96, and at the time, it was a dealer only item @ around $100. It stands for something like Differential Pressure F? E?. I gues over time they fail due to the moisture in the system. I took mine apart and it was all wet inside.

Im new here, so forgive me if I dont follow set procedures on this board.
Im getting the P0401 code as well. I was planning on replacing the DPF Sensor & EGR valve since the cost isnt too entirely high.
My question is, where the heck are they located & how much trouble are they to replace? Is there an online manual or schematic?

NEVER replace an EGR valve for these code unless you KNOW it's bad. They very seldom fail.
Guys, especially all you new ones in this thread, it is very important that you identify your vehicle's specifics, ie, year engine, transmission, drivetrain. Put it in your signature and you won't need to edit or add to any of your previous posts. A simple entry such as "1999 4.6 4R70W 4X4" is the perfect information to give.
DPFE sensors from certain years have an extended warranty of 2 years/24K miles beyond your original 3/36 warranty. Your faulty DPFE sensors may be free if you still qualify.
Go to the top of every web page, click on Recalls/TSBs, select Full Text TSBs, then review the full text bulletins for your truck. You can also enter DTCs as a SEARCH argument of the TSB database to see if there are any relevent bulletins for your current fault code. (There are several TSBs for the codes currently under discussion).
Many codes are extraordinarily common subjects of discussions. A simple SEARCH of the website using your fault code as the SEARCH argument will bring up previous discussions.

I cannot add a signature until I have 26 posts.
This is my vehicle info:
2001 Ford F150 1/2 ton 2WD V8 4.6L EFI
My DPFE Sensor is out of warranty. I want to start by changing it and cleaning any carbon build up.
I will take projectSHO89's advice and not jack with the EGR Valve.
Where can I find the DPFE valve? Is there an online schematic or detail for finding & changing it? Or should I buy a manual?

The DPFE is on the side of the throttle body and it has two vaccuum lines attached to it. Two screws hold it in place. I just replaced mine and it didn't solve the problem. I removed the throttle body this weekend along with the EGR valve and WOW, tons of carbon build up. Got it cleaned and the light is now off. Still idling rough though. Changed the fuel filter too as well as cleaned the MAS. I have the same truck as you, 2001 F150 4.6 2WD SUPERCREW AUTO.
