2004 EB 5.4L 2WD. Was driving and suddenly the truck began to stutter and putt putt. researched and was very afraid it was gonna be a bad plug. Bought a OBDII scanner and that code eventually lead me to this video. I found that there was a break in the larger of the two hoses in this video. Replaced it and now the truck is running great. Mileage is back to normal also. This is the second time I have found a broken hose guys. Always check your hoses first. Many thanks to the poster.
Bought my sensor from auto zone. check engine light went out for a little while, then came back on. Same code. Went to ford and bought the oem part, not much more expensive. Light went out and has ran for years. The egr valve and hoses all looked good and clean at the time as well. Cheap part. Go with the oem when getting this sensor.
The downstream hose is connected to the DPFE sensor. There will be two hoses that go into the two small connections to the EGR Tube. You will want to buy these hoses from the dealership due to the fact that they are reinforced and will not collapse as with any other rubber hose. Measure these hoses, but they will sell them by the foot at the dealership. They are 2 different sizes. Replace both at this time. They tend to break around the sensor and allow too much air in cusing your error code
The 2 hoses connect to the DPFE sensor and the 2 "limbs that come off the EGR Tube. If the rubber hoses are not connected to the DPFE sensor that would be a problem throwing the code.
You should smell the coolant if you have a leak. Also the coolant should leave a small puddle trail from the leak. Water will evaporate, so if you are not using the correct mixture of coolant, it may just not leave any residue. You should check near the thermostat, the lower part of the housing should sit above a small trough that may collect some of the coolant. You may just have a bad thermostat which will cause it too overheat, thus burning off the coolant.
My Story......Have a Eddie Bauer 2004 Expedition got the dreaded P0401 changed the DPFE Sensor, EGR Valve and cleaned throttle body without removing it with throttle cleaner. Code went away but came back a couple days later. Decided to check the EGR Solenoid with multimeter before diving in to remove throttle from engine for deep clean. Solenoid read good so decided to start taking things apart...AN THERE IT WAS not the two hooded green hose with one going to the EGR valve but the other one had that crappy spongy rubber like material Ford used as an elbow to connect the hose from the EGR solenoid had fallen apart an had holes in it....Problem solved FYI people don't waste time like me check all hoses in the EMS system not just the unit throwing a code.
he air intake manifold must be taken off completely. There are 2 small ports that will be clogged with carbon buildup. Anytime your car runs to lean, or too rich carbon buildup is a byproduct. It is going to either clog the ports, valves. When a hole is present in the EGR hose, the intake valve is the first to clog and the most time consuming to clean. Just use a small wire bristle brush will clean this out with a good cleaner. Spray alone will not work on this.
.just curious. I work on my wife's 1999 4.6 liter model..It has an intermittent subtle loss of power. We took to an auto part store called and it has a P401 code.. DPFE code. I've never cleaned the manifold but we've had the car for about 10 years. I would imagine that there is some carbon build up at the very least. I used to take the Idle air control out and clean it..I think I finally replaced it I'm was a electronic tech for about 20 or so years. TVs VCRs .. Garage door openers, Sat.Systems. I've seen a lot of things replaced and often it was a transistor or IC. It goes grain to just throw money ( Scarce commodity,) at something. My problem is intermitent, carbon might due that. I think I'll look into cleaning that.
I have a 2001 Ford Expedition and I just did a tuneup and now the check engine light is on. As I was driving it felt smooth until 20 minutes into driving and now it's stalling as I'm driving.
Hello. I have a 2004 Ford expedition 5.4L V8. My truck is burning excessive fuel. I have changed my fuel filter & EGR unit. But I am still going through fuel super quick.
please tell me what that green vacuum hose that is connected to the egr valve is called because mine snaps off and i need to replace it but i cant find it anywhere because i dont know what it is called
What engine codes are you receiving? It sounds like the intake manifold may be clogged......If you are running rich or lean, carbon is a byproduct that will clog the two small holes in the air intake manifold. This will need to be cleaned, but I would also check the vacuum gauge pump as it would be prone to fail.
2004 ford expedition 5.4 l Triton V8 Replaced TPS, MAS, Crank post sensor, air filter, fuel filter, throttle body gasket, PCV valve and I still getting a too lean code. It idles fine when cold but idles rough when car warms up. It acts like it wants to die bit runs fine driving. Any help please it has 140,000 miles on it. Also replaced plugs and coils.
On my 03 navigator it turned out to be the air hose it will keep coming off when driving so I replace the air hose and problem fix. The air hose expanded with the time and became to large for it to hold on to the lines but the new ones had a strong fit so no more sliding off.
Could this happen to a v10 excursion? I have had intermiten no start/minimal to no crank and I kept thinking it's the fuel pump. It typically hapens after I've driven for a while and if I let it cool down, it may or may not start back up. No codes made it very difficult to pinpoint the problem...When I looked up on the OBD, it has a p04..code stored. Nothing specific, just P04...
I have a 2003 Ford Windstar SE and the codes that were on the diagnostic machine that was listed on it were P0171 and P0174 Bank 1 and Bank 2 were listed. Can you recommend where to get the sensors and what kind and how many? Amazon has some universal types, but can you help me choose the best ones at the lowest price? Thank you.
Where exactly was the air intake manifold clogged and what was it clogged with? I have the same code, P4001, I've changed the same part you have, and while I haven't done it yet, about every 30,000 I'll disconnect the air intake and spray down the throttle body flap with carb cleaner because there is carbon and dirt buildup on that flap....
Hello my name is Chris I have the same problem and same truck same code and I changed the dppf sensor the hoses to it and the vacuum solenoid and the EGR valve
I have a 03 Expedition 4.6L and my check engine light is on. Replaced all spark plugs and replaced 2 coils and both O2 sensors on the passenger side. Engine still hesitate like it wants to cut off and I lose pressure when trying to accelerate up hill do you have any suggestions on what that may be?
Carbon is a byproduct, it will become hard and build up on the manifold. Think of it like plaque on a tooth.....over time, it will build up and then cause problems.
I have a 2000 ford expo. with a 5.4, runs ok in town but when I hit 60 or more it seems to cut out and lose power. I took it to get a code read but the parts guy said there is nothing as if the port has no power, what does this mean......
I just checked my dads 2001 expedition and those two hoses aren't connected to anything (the rubber end) where do they connect to? He also has code p0401
HELP I have a 2001 Ford expedtion 5.4 engine i am having issue with acceleration we have changed maf sensor air intake sensor gas filter still having issues throws code p0442 some hose were also changed still the car is not accelerating correctly she runs smooth in park idles great cant tell its running from dead stop till 20 mph ok but trying to go on hyway she just bogs
I purchased a '01 Expedition 5.4 cheaper then expected, because it was doing the same thing. Sluggish during acceleration and would not pick up speed. The owner could not figure it out so he sold it to me for cheap. After multiple approaches, it finally fixed when I changed all 8 spark plugs myself. I didn't trust the mechanic to get the ones in the back. That did the trick! I couldn't change the boots at the time (funds), but changing the plugs seemed to fix my higher speed issue. Good Luck!
can some one help me with my van as it over heats. i have a ford transit 2002 we keep topping up the header tank, i have put on a new head gaskit and it is still overheating but where is all the water going.

This video really helped me out with my Ford expedition
I cleaned my 01 4.6 last night took me an hour in a half to take apart clean and reassemble truck runs good i was 100% clogged both ports
What did u take apart?
The 2 hoses connect to the DPFE sensor and the 2 "limbs that come off the EGR Tube. If the rubber hoses are not connected to the DPFE sensor that would be a problem throwing the code.

Dpfe replacement worked for me!!!
Super fuckin happy. I love you tube!!!
Had this issue also, what i found was the hoses hooked up to the DPFE were in the wrong positions. I changed around so far so good.
What position do they go in?

It may be the air vacuum. It will sit back behind the manifold....in the video it has a green line that comes out of it...try here first.

May I ask what was the size of the inner diameter of the egr hose? I got wrong one today ...the inner diam was 4mm too small.

Q: What part of that tube do you blow out.. or how do you get to it?... Do yo blow it out from on end or are you removing it completely?

Hello my name is Chris I have the same problem and same truck same code and I changed the dppf sensor the hoses to it and the vacuum solenoid and the EGR valve
And I cleaned the boty throttle like you and had a mechanic lot at the car and said everything is good but the code still comes on any thoughts?
I have a 03 Expedition 4.6L and my check engine light is on. Replaced all spark plugs and replaced 2 coils and both O2 sensors on the passenger side. Engine still hesitate like it wants to cut off and I lose pressure when trying to accelerate up hill do you have any suggestions on what that may be?
What was the problem?
Did you ever fixed your issue?
@@mtsanchez27 Yeah got rid of it 😂😂😂😂
where do u find the emission control sensor on a 5.4 triton in a 2003 fordvf150
Would it bogg down randomly on the gas?
I have a 04 expedition 5.4 with p1405 code, would this cause the smell of gas because I got that going on too. Thanks
I need to kno how the dpfm hoses go
What's the size of the vacuum lines

change the fuse for car lighter fuse r eng fuse
I have 03 ford expedition and I'm having trouble keeping the hoses on. Replaced the sensor and hoses but one just keeps blowing off. Help!
Catalytic converters are plugged.
Try a clamp or a zip tie
I just read somewhere that a bad egr sensor might not read a p0401 & that it could actually trigger the p0171 & p0174 codes (too lean). Is this true?
I have a 2001 Ford Explorer Sport, 4.0, V6
im replacing my hoses but one looked like it semi melted and blew off
Lhow. Can i purchase this DPFE EGR SENSOR FROM EBAY FOR A 2001 FORD EXPEDITION 4.6
How can I 1⅞
purchase This EGR SENSOR FROM FROM EBAY ITS A DPEF EGR SENSOR FOR. A 2001 FORD EXPEDITION 4.6
I just checked my dads 2001 expedition and those two hoses aren't connected to anything (the rubber end) where do they connect to? He also has code p0401
To the dpfe sensor
Did you ever get rid of these codes?

Did you ever fixed the problem with your truck?
When I go to a shop, what exactly do I ask for? hey please unclog my intake system???
3 step treatment
thx .. doing it right now ;)
can some one help me with my van as it over heats.
i have a ford transit 2002 we keep topping up the header tank, i have put on a new head gaskit and it is still overheating but where is all the water going.
what bout your water pump
Which engine does this car have?
4.6 I believe or the 5.4 triton
were you getting bad gas mileage
Ours is right now
Video is so shaken I got dizzy.
Lol now it’ll will probably cost around 500 for them to do that. Gotta love inflation
Manitake infold lol
10 dollar hose your nuts auto zone has them for 1 a foot bad sensor take continuity readings
