Ford Super Duty (1999-2016) :: 2003 F250 - Service Engine Light Keeps Popping On And Putting Out Code P0401
I just bought a 2003 F250 from a used dealer. Unfortunately the service engine light keeps popping on and putting out the code P0401, I have replaced the EGR, cleaned the inside, and cleared the code. However it continues to keep popping up and then it will turn off after a couple of days. I mostly drive in the city and the code generally only pops on when I drive on the highway. I have also noticed a lack or delay of power, when I really hit it hard, I think its because the computer is keeping the egr valve open. What it could be?

I have a 2003 F250 Super Duty 5.4L V8 with no heat. It wasn't missing, running funny or blowing white smoke out of the tailpipe and there were no coolant leaks nor did it overheat. Thermostat has been replaced twice, heater core flushed twice, water pump replaced, fan clutch replaced and blend door works...Cabin airflow gets colder when turned from hot to cold. This thing is sitting in my driveway and I am about to push it over a cliff. Did I mention it only has 56,000 miles on it?
Coolant was drained to replace water pump and flush heater core (again, water ran through in both directions with no stoppage). 3 gallons of undilluted antifreeze was put into the overflow bottle to be topped off with water...the coolant went in and stopped. Engine was started to force coolant from bottle...coolant backed up into the bottle and out the top. Heater core inlet hose is hot and outlet hose not very warm if at all. Upper radiator hose is soft. Didn't check lower radiator hose as I was a bit peeved and slammed the hood closed and called it a night. I have been throwing money at this thing that I do not have and am at my wits end with it.
Ford Super Duty (1999-2016) :: 2004 F250 6.8L - Engine Just Shuts Off No Code
I've got a 2004 f250 4x4 crew cab that is driving me nuts. It runs great, but sporadically it will just quit running. Tach drops to zero. Engine is still turning, because it usually restarts by itself as long as I am moving over about 45. If not I can pull over, put it in park and restart it. Sometimes it sets codes, never the same ones and usually not something even related to the problem (transfer case solenoid for example). Most times it doesn't set any codes. I have changed the plugs and coil packs on all cylinders. Right now it is showing the P1000 code so I am suspicious of the pcm or the wiring to it. I think the tach is the only thing dropping out on the instruments and all the instruments are powered through the pcm.

I threw a code on my truck for a P0611 FICM. I checked it out and I had 48 Volts DC with key in the on position and 47.8 Volts DC with the truck running. I know that if it is fried, the second reading should be below 45 VDC.

Dreaded insufficient EGR flow. I've read I should clean the EGR ports.
I can't really find where these are? I took the throttle body off.
What I should do with this thing? I also get a hesitation on initial take off.
1999 F150 4.2 V6 ... 160k miles on it. Runs good otherwise.
Ford F-150 (2004-2008) :: 2007 4.6L V8 - Code P0401 - Insufficient Flow - EGR Identification
I am preparing to combat the old P0401, Insufficient flow issue. While looking at the steps in Alldatadiy the very first decision essentially forks on "EGR System Module" or "Others".
I am just guessing that, since the choice is there, some engines will have one and some will have the other. But I thought I'd come here and see if I could learn a little more about it.
How can I tell what my truck has? I'm sure there is some difference...
Santa FE SM (2001-06) :: 2004 2.4l - Code P0401 / EGR Insufficient Flow
EGR insufficient flow. EGR valve was pretty bad looking seemed a bit sticky when opened so I replaced it along with gasket. Reset the computer but check engine light came back on code p0401 again. I know you can test by pinching the yellow striped hose at the throttle body to see if the solenoid is bad. The engine will stumble a bit when you pinch it closed, or so I am told. However when I pinch the hose, nothing happens. I do notice that the car does idle kind of roughly.

Ok says injector pressure sensor low first guess was the upgrade to the blue spring. Did that code clear for a day then comes back on looking at the hfcm but kinda unsure? Came on after we got the real cold snap and i had to buy a block heater I don't see one on here i also added diesel 911 to the tank this is a 05 f250 w 6.0l....

My 99 F250 with a V10 had an abs light come on and then it would go off. Now the ABS light stays on and it drove fine for a little while but the other night the Service Engine light came on along with the ABS light. Tranny was shifting harsh, winding out and I scanned the codes and got P0500. Is it the sensor on top of the rear differential or is it the ABS light causing the problem?

View 3 RepliesFord Aerostar :: P0401 Insufficient EGR Gas Flow Code
My '96 4L developed the infamous P0401 insufficient EGR gas flow code 6 months ago. Rough running. Forgot to license it, now the St. Emissions Test was due before I could get new tabs issued. Finally got some warm dry weather to work on it. Started with the electrical measurements per DPFE graph of EGR flow vs electrical output to the PCM.
Showed the DPFE sensor failed, low V output max 2v. The old OEM aluminum body DPFE sensor was still in the old girl after 16 years. Corroded internally and ext., one hose nipple almost corroded off. Eureka. Put in a new Motorcraft plastic body upgrade. Same darn code.
Retested everything from the EGR vacuum valve that feeds the EGR valve to the new DPFE and then the EGR tube from the exhaust pipe. All tested ok electrically and leak wise. No fresh air leaks in the EGR V or EGR tube.
All pointed to restriction in EGR gas flow when PCM demanded it. Ran small stainless steel wire down the upper EGR tube line nipple to the EGR orifice trying to clear carbon build up, still the same P0401. Poured several cups of paint store acetone down each EGR tube hose with engine off and at 2k rpm to emulsify and dissolve the exhaust carbon out. Engine vacuum sucked the acetone up thru the EGR valve also cleaning it internally.
Let set overnight and took out for test drive. Still P0401. Almost ready to drive the green beast to the crusher of death.
Poured more acetone in the EGR and let set for 2 days prepared for the emissions station test failure then repair at emissions cert. shop with a shop waiver for no effective repair. Decided that the EGR tube or EGR valve were leaking fresh air, rusted and corroded. The end nuts on the tube were rusted away. EGR tube NLA from any source.
Went to the emissions test today and passed flying colors. NO P0401, drove all day on business. Got relicensed.
The old girl runs and drives like a dream, she's actually parked and sleeping in the garage tonight all pretty and shiny with a wash and wax job, got a reprieve from the Jaws of Death
Ford Super Duty (1999-2016) :: 2006 F250 - CEL And Error Code For TPS Occasionally Comes On
Engine light and error code for tps occasionally comes on , then stays off a while. parts store said it was ok (shows full range) , but ford has an update for computer to fix. engine is v10 and parts store erased code and it hasnt come back. the only indication that something was wrong is the light coming on and once on the interstate at high speed , then the off ramp slow down, the engine seemed to want to stall as if engine not matching actual speed for a few seconds, then it was ok again. I was out of town and the mechanic that looked at it told me to go to Ford for an update. He tested the tps and said it was ok.

I have a 99 f250 5.4l 2v with 165000. just two weeks ago i went to start up the truck on a job site to take lunch and it was running really rough. I talked with a mechanic at my shop and he said that it sounded like the aic or that i needed plugs. I went and bought aic and plugs and installed them all in one day. I unhooked the battery before i did any work and have changed the coil packs about 3-4 months ago when it was jerking at highway speeds. I am at a loss.
Read so much on the site about could be this or that and cant afford to through money at it like the govt does. I replaced the ait(air intake temp sensor) and the ect(engine coolant sensor) after i got a code from oreillys that said p0113 which is high input on it. I have read it can be so many things and it seems to be running rich because i am getting about half of mileage i was getting before problem started. i need a fix soon as i must drive the truck to work everyday which is a 52 mile trip total.
Ford Super Duty (1999-2016) :: 2005 F250 - Code For Cylinder 3 Misfire
My 5.4 F250 with 200,000 miles having many problems... It all started a few months ago, when the cam needed to be replaced, and a cam phaser was also replaced at the same time. It ran fine after, then threw a code for cylinder 3 misfire. The guy I took it to said it was due to the huge crack in the exhaust manifold and that was messing with the o2 sensor coming up as a cylinder 3 misfire. So, got the new manifold and it was good for a few weeks.
Now, starting the other night, Friday the 13th, it threw a CEL when I was coming into the driveway. It had been throwing a code every once in a while, and I brought it to school to scan it Friday the 13th but there was no code. So, I assume that it is an intermittent problem, no big deal. When I go to get in my truck to go to work a few hours later, the 5.4 cranks... and cranks... and cranks.
I get it to fire up, and it dies again. Run codes, and it says that the cam positioning sensor is broken. Replace both of them, still acts up ie. doesn't start when it does start it runs very rough and stalls. Get it up to my uncles shop, and replace fuel filter.. Still runs like trash. Run codes now, and it says rich/lean in bank 1.. My uncle tells me to move my truck out of the shop, so I start it up, and it runs great. No hiccups, it idles perfect as I move his truck out of the shop first.
I park my truck outside and let it idle for about 10 mins, and when I come back out it is still idling, perfectly fine. I get in, put it in reverse, and get about 20 feet when it dies and will no longer start back up. What could be going wrong?! Sick of throwing money into this thing! At one time while started up in my uncles shop, it was blowing black smoke, as if it was a diesel!
Ford Super Duty (1999-2016) :: F250 - ABS And MIL Lights Are On / Code Is P0500 - VSS Malfunction
I've got a 99 F-250 6.8L V10 manual 4WD with no speedometer or odometer. The ABS and MIL lights are on. Code is P0500 - VSS malfunction.
This started when the previous owner hooked up some large LED backup lights to the factory wiring. Something smoked under the dash. He then moved them to a relay-switched +12V feed. He reported that the backup light fuse did not blow.
Ive tested the backup light fuse and the recently replaced VSS. Fuse is good and the VSS tests ok for Ohms and gives AC voltage when the tone ring turns. I pulled the fuse panel, GEM, and PCM. There's no visible damage anywhere there. I'm stumped. Tomorrow, I'll dig for any melted wiring under the dash....

View 5 RepliesFord Super Duty (1999-2016) :: Random High Idle Sometimes When Put Into Park - Codes P0300 And P0401
1999 F-250 V10 .... Truck was running perfectly fine except for a random high idle sometimes when put into park but if I gave it a good rev it would drop back down to normal. I assumed it was a dirty IAC or something and figured I'd get around to it later kinda deal. I also had a coolant leak from what I thought was the intake manifold to head gasket on the drivers side right in the front where the upper radiator hose meets the intake manifold so i added water here and there no issues.
One night I need to pull a trailer and didn't have the wiring set up for it in the back so I stopped at advance auto and bought one of those kits that plugs into your brake wiring harness and then plugs into the trailer. I tested it in the parking lot with the trailer and it was all sorts of messed up. My reverse lights stayed on my brake lights didn't work either etc. Turns out it was for the wrong years but plugs matched up coincidentally. I returned the kit and drove home just fine.
Next morning on my way to work truck started misfiring like crazy idle was bouncing all over the place lack of power etc. I took it to advance again after work even though no check engine light came on I still pulled 2 codes. P0300 which is multiple random misfire (no specific bank) and a P0401 which is an EGR Insufficient Flow code. I took it by a local shop I get my oil down at and they told me it was probably the fuel pump that they go bad in these trucks alot.
So I replaced the fuel pump and the fuel filter. Nothing changed so I thought maybe that coolant leak had dripped down to the plugs or possibly the intake gasket was getting worse and leaking coolant into the air flow ports since it was thought to already be a problem. So i pulled everything off the top and firgured id go through it all why I had it apart. I replaced the intake gasket but noticed when i took it apart that it wasnt the gasket that the head it self had a small pin hole leak in the very front where the coolant fed into below that upper neck that bolts to the intake manifold. I patched it with jb weld/ quick steel/ and rtv. Yes I know it wont last but just for the time being until I figure out the main issue. Replaced the plugs with motocraft plugs checked all my coils for grime and corrosion or what not and they all seemed fine and cleaner than expected. replaced the gaskets and threw it all back together. I also cleaned out the EGR and IAC with air and brake cleaner etc.
Blew all my lines out with air and everything seemed fine. I also replaced my DPFE sensor. Started it up ran fine at idle for like 5 min no coolant leaks or anything so I thought I was golden then about 500 ft through the neighborhood on a test drive the exact same misfire came back doing the same thing with the idle etc. I'm going to check my fuses tonight but I'm starting to think that maybe when I plugged in that wrong wire adapter for the trailer that I may have screwed up something with the PCM. Only because the lights were all out of wack and literally the next morning I started having these issues. I'm lost if its not a fuse. I would really hate to buy a PCM and not need it especially after all the parts I've bought and not needed already.
The vacuum lines all seemed fine and intact as well with no cracks or leaks.

View 9 RepliesFord Super Duty (1999-2016) :: 2005 F250 - Hard Start - Misfire Code?
I have a 2005 F250 with the 5.4. This truck has been one thing after another, as you can tell from my other posts. The problem this time is, if it cranks hard to start because it's cold(can be anywhere from as high as 32, but usually in the teens) it will start just fine, then several minutes later throw the check engine light. Put the scanner on, like clockwork, 4 codes, always cylinder 1 misfire pending, misfire on first 1,000 revolutions pending, cylinder 1 misfire confirmed, misfire on first 1,000 revolutions confirmed.
Sometimes you can hear a slight lope in the idle when it does this. Clear the codes, runs perfectly fine. It will never do it after it's been started for the day. Some days you would think for sure it would throw it when it's frigid and the winds been blowing on it, it doesn't bother, other days you wouldn't think it would, and it does.Can the computer think that since it didn't start right up, it misfired?
