Thanks buddy. My mother's Sport Trac has this code. I deleted it and drove it for a while and it didn't come back. Hoping it stays off as she's a total hypochondriac about her vehicles.
I found the valve to exhaust manifold pipe leaking at the seams where they put the flex section between two steel pipes on a 1996 5.8 throwing a P1400.

Yes sir. I can't take credit as I found that solution for the ping on an auto forum somewhere. No promises of course, but was lucky and worked for me and is not terrible expensive part on mine. Think it was less than 30 dollars on my truck.

02 explorer 4.0 sohc here. Changed dpfe sensor 2x along with the connector, new egr valve, new Egr solenoid, took the line off the exhaust and cleaned it with a wire brush and throttle body cleaner, cleaned the port inside the intake manifold, and same code keeps popping up!!!!
same here. Everything is new oem motorsport I think I have an exhaust leak in cylinder #2 after repairing a spark plug ejection. when they retapped the threads it caused a whistling noise during accelleration. But I also have a bypassed vacuum canister that might be contributing to the problem
Have had P0401 code for about a year, really want to get rid of the service engine light so about a year ago i changed the DPFE sensor but not with a oem one I’ve been hearing that if you don’t use an oem one might not read it right ? I also bout 8 months ago cleaned the throttle body but only from the intake on top, could it be that I need to take it entirely off and clean it all ? Or should I just replace the egr valve itself sitting at 150K miles 2003 f-150 5.4L
I have a Ford Taurus 2006 and it hard to check engine light come on and I just got an oil change and it was showing me low oil pressure light constantly coming on when I stopped and I took it for a diagnostic check and this is the code that came up
I have a 2000 Lincoln navigator with the same code when the engine is cold it hesitates between 1000 and 1500 RPMs when you rev it up between 2000 and 3000 it has a miss sometimes it stays sometimes it goes away any suggestions
Its possible you have two problems. Tackle one at a time. I don't believe this code on that vehicle will cause any noticeable engine performance issues.
i got a 98 f150 4.6 with a code p1299 and p0401..for the p1299 code ive replaced coolant temp sender and the cylinder head temp sensor but now i have a hole that just magically appeared on my rusted exhaust manifold🤔 im just wondering could this hole on my manifold cause p0401 and could it also be the cause of the ltfts on both banks to read very rich at about -19?...also p1299 reappeared any suggestion would be very helpful
I'd say the exhaust leak probably is affecting your fuel trim. P0401 is most likely not caused by the exhaust leak. I'd suspect the DPFE sensor or clogged EGR ports. P1299 sets if the vehicle is over heating. A bad CHT sensor could cause that code but it's more likely that the vehicle is actually overheating. You'll need to figure out if it is actually overheating and why. Hope that at least gets you pointed in the right direction.
Have you had a cat converter starting to plug up cause the hoses to burn up at DPFE sensor? Seen it once awhile back when I was a Chrysler Tech. Great info and video. You packed great info and less than 5 minutes. Thanks!
Anytime I've seen hoses burnt going to the DPFE they were usually the wrong type of hose. The correct hose is made of a special rubber that resists burning. I suppose it could be possible that a clogged cat would cause that though. It makes sense to me anyway. Exhaust temperatures in that are would be higher.
I have a 03 crown victoria, 4.6 2v. Yesterday i developed a bad hesitation and breakup. I changed the coils, plugs, fuel filter, and cleaned my maf, and cleaned the "charcoal canister" underneath the tank. Its still doing it. Any ideas? I did the egr test where you stick your finger over the hole where the foam protector was and it didn't die, just ran very rough

I have a 1999 ford Taurus 3.0. I changed the sensor but now getting the po401. could I just use some sea foam to clean out any possible gunk in the system and see if that works
i have an 04 explorer that is dying every few days on short drives , its throwing this code po401 & po193 fuel rail pressure somthing, im lost this helps a bunch, thanks also if you read this could you give any tips about the po193?
I have a 2006 explorer and had the same issue, engine light on, code p0401 and car would just die after 15min of driving. It would start after few moments and drive normal but then again would turn off at the first signal light. I changed every possible related part like egr valve, pcv valve, O2 sensors, evap purge valve and even the cats. Nothing worked, still same code and cars switching off after some driving. Turned out it was the whole ECU unit!! Paid the refurbished one from eBay 250USD and boom!! Car now drives like a charm!!
Yo what’s up my dude idk if your still active or not but I have a question. So I got that code replaced the EGR thing your 2nd option and it still has the code right. Okay so when I drive it. When I cruise at about 45-50 or so sometimes slower it humps like it stutters a lot when I press the gas softly. But if I press it hard it goes fine no problem. Also idles perfect sounds fine.
Usually a studder when under light acceleration at that speed, especially when going up hills, is indicative of an ignition misfire. It's possible you need plugs. But as for the code, have you checked to make sure the ports aren't clogged up?
@@BarboursAutoHelp no tbh I’m not a Mech savy person. I know the basics but not much. I thought about that but if I had a missfire it would cause a check engine light no?
I replaced the DPFE sensor, the EGR vacuum regulator solenoid, and the egr valve on my 2000 Ford Ranger 2.5L and I still get a code 0P0401... Comment, please. Thanks!
It's quite possible that the egr port in the intake is clogged. If you where to apply vacuum to the egr valve while the engine is running does the engine want to die out on you? If not, and the egr valve is actually opening then your port is probably clogged.
@@BarboursAutoHelp Thanks! I will check that out. What I find strange is that there is no hesitation on acceleration nor rough idling while driving, but the check engine light on just drives me nuts... I appreciate your suggestion! Thanks, again.

Hi i have a 00 Mustang gt and the hoses on the dpfe pop out and get super hot. What might be causing the problem? I'll be replacing the egr valve, dpfe, and the regulator
I'd replace the hoses when you replace everything else. Now those hoses are special. They are designed to withstand high temps. So be sure you get hoses designed for use on a DPFE sensor. It is normal for those hoses to get hot.
My 98 f150 was stalling and I had to floor the pedal to move it forward . I got code P0401. Is this the issue? I had codes P102 and P455 as well that I’ll look into, but does Anyone know if this is why a truck would turn off? Is this piece that vital?
No, I don't think the EGR system is causing the truck to stall. I'd be more concerned with the p0102. You may have a problem with the MAF sensor. This will cause the vehicle to run very poorly. Usually a dirty sensor is the cause.
Oh ya,that's the ticket, when I activate EGR valve at idle engine bigs for a second, my understanding it should die. To me acting like low gas flow, so ill net a dime to a dollar intake potrts,clogged, in check in morning and let ya all know if that was the problem, thanks any thing on purge valve, hold,vacume has 12v I do not have scan tool to send ground to the valve, have a po443 code valve circuit, any way to check out problem without scan tool command?
High voltage? Usually means that the sensor is seeing too much flow or there is an electrical issue. What does the sensor see at idle? Have you monitored the data stream on it?
i had this code for a few weeks on my 1999 expedition 5.4, unhooked the battery for 5 minutes and the check engine light quit showing, it wasn't driving weird at all
