2001 F150 SuperCrew 5.4L.
I got a P1405 code and I am going to replace the DPFE. Should I go generic or get the Motorcraft part? (so far, generic $79.00 - Motorcraft $148.00)

Thanks in advance for your feedback.

 

Motorcraft. Ford has updated the DPFE for these trucks and the aftermarket has not followed suit. Check with the website sponsors like Y2K Ford Discount Parts. Should be about $70. Good luck!

 

I just replaced mine with one from one of our sponsors (www.rockauto.com). it wasnt FORD OEM,but has worked flawlessly.I believe it was around 40.00. It did have an insert in the box concerning the fact that it had be "upgraded" to the Ford specs.Dont remember the specifics,but my CEL light hasnt come back on,and so far Im tickeled.
Dont get me wrong...I have no problems with Ford OEM components,and normally stick to factory parts,but in this case the gamble paid off.....

 

I think you will find the after market stays more updated than OEM. They see what fails on oem , then improves upon them to make a better product . That DPFE from OEM is metal which seems to fail often. After market came out with a plastic version which lasts longer. OEM has now followed along with a all plastic version.
A lot of aftermarket have much longer warranties than OEM.

 

I got the new DPFE from y2k discount parts as recommended. It was $70.00. The local parts store had the vacuum hoses for the install. I had to remind the guy that the hoses are two different sizes. He wanted to sell me one size hose for both. That was $6.00 total for a foot of each.

The install was easy. About 15 minutes. I then cleared the code. No issues so far.

Thanks to everyone who posted. I certainly got the complete range of responses from OEM is better to generic is better and others going with generic and hoping for the best. Sometimes I wish I could call Ford, get the friggin' engineer who designed the darn thing and get an honest answer as to what the situation is with any part, but we don't live in Fantasyland...

 

I have read plenty of posts where people installed aftermarket parts only to have the code return. I would trust Motorcraft to resolve the issue more than aftermarket. Sure some companies try to find out what is wrong, but most aftermarket parts are trying to build cheaper alternatives, and cheaper is rarely better.

 

ford has changed this part years ago and it is made of plastic

 

...Are the rubber hose "special"? or are they just regular rubber fuel line hose?

 

Special high-temperature hoses to take the heat of exhaust gas.

You can look them up at rockauto, the SMP brand has more info available there on the material.

 

The plastic version of DPFE was made as factory at least 12 years ago.
The hoses are 2 different sizes.
In the past, after market supply of these units often failed due to quality testing not tight enough.
The reason is the test requirements on the truck are very tight to the accuracy in the +/- 2% range for failure as dictated by the EPA.
The PCM program tests for excessive flow, to little flow, the connecting hose leakage etc..
These test also are affected by outside conditions involving the flow tests as well as the DPFE not being able to report the test results to the PCM.
The DPFE is a sensor only. It does not conduct or control any testing.
Doing any testing of the DPFE is nearly fruitless as you can't duplicate the test conditions unless you know what they are and have equipment to set up the pressures. Electrical test seldom have any value.
If the connector or harness is faulty, it becomes an exercise of observation.
The EGR system is tested 2 times per driving cycle. Once a failure is detected 2 times, a code is set, CEL comes on, the system is suspended from operation as long as the code is still present.
The effect of this is no drivability change but fuel mileage can suffer somewhat for other reasons due to the way the program handles other parameters when it is working vs. suspended.
Good luck.
