Ford 6.0L Power Stroke Diesel :: 2004 F250 - EGR Low Flow Code
Jul 1, 2016
I am driving a early 2004 F250 CCSB with a 6.0l. I have a Code that is for an EGR Low Flow. I have a Scan Gauge II that I have been using to try and determine why this is. I have replace the EGR Cooler (unrelated), the EGR valve, and the MAF.
My EVD and EVM are tracking. My IA1 reads a letter (B usually) and 3 numbers that are in the 6 to 900 range. My IA2 appears to read normal with atmospheric temps at start up and goes up and down IAW the EVD and EVM readings. My FIA (already programmed) reads outside temperature along with the overhead console. The EBP reading doesn't exist, it is blank.

My truck threw a CEL after the first start today. The CTS reports it twice. I noticed it about two minutes after start.
P02E1 - Diesel Intake Air Flow Control Performance
The air box gauge is green and it doesn't reset when I push it so that appears to be fine.
The one thing I can easily notice is the sound of the turbo. Typically when I stop and park, the turbo spools up, then down, then spools again and gives a sigh of relief and it's then silent. It's not doing that currently.
Now, I can hear it constantly when parked and it spools down after I turn off the engine, even two minutes later. That is not normal for my truck when I wait for the above to finish its routine. When I start the truck, the turbo immediately spools to where I can hear it which is also not normal, as if it's building 0.5 psi. I realize that's funny to say on a turbo diesel but I know the sounds of my truck. The EGT's are fine, EOT, ECT, TFT are fine and I can build boost when driving without issue. I took the drive to work easy this morning so the highest I noticed was 10 psi.
I restarted the truck after a 20 minute drive to the office and it didn't clear the CEL. The CTS squawked four times when it woke up the second time but it didn't show me which PID it was upset about.
I'm thinking this has nothing to do with the CAI and this is something downstream of there. EGR related? I haven't opened the air box yet, at work and in dress clothes so that'll need to wait. My past four or five regenerations all started between 1.94 and 1.97 soot gpl. That is also not normal and is something I have been keeping my eyes on. Currently the DPF is at 2.10 so it has made it further. Normal behavior (post emissions flash) is above 2.54 soot gpl for an AR.

I'm going to do a weld-in-plug delete in my RV in the next couple weeks, and its a crapshoot apparently if it'll throw a code. My immediate concern is I want to go on a trip right after, and I won't have time to fiddle about getting an SCT tuner to turn the code off. What I definitely don't want is a code for EGR flow restriction to eventually cause my motor to go into some kind of limp mode while I'm in the middle of a long drive. Is this possible?

The truck in question is a 2004 6.0L Excursion, stock original turbo, no tunes, and EGR cooler delete done 1 year ago. Scanned for codes and none were found except for EGR insufficient flow P0401 code which is due to the EGR cooler delete.
Upon startup (no issues there) the VGT reads 67-70, now once the truck goes to high idle to warm up (1150 or so RPM) the VGT slowing climbs to 85 and stays there. If I blimp the throttle or step on the brake it goes back to 67-70 at normal idle. This has been happening for a few months now on a regular basis. I have checked the MAP, BARO, and EBP readings at KOEO and they are all within 0.6 of each other (14.4-15.0). The EBP tube was checked and cleaned (no buildup present)..

Ok just bought a '04 F250 Diesel. Loving everything but can't get the keyless code to work. The keypad lights when I touch it and I have retrieved the 5 digit code from the "Bosch" box behind the radio. No deal. Locks don't react at all to the factoy code. Know what? I read that there is a list of all the possible codes. Where can I get that list?

My truck threw a P2073 code. Its Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Idle. I do have aftermarket intake. It threw this code 2 weeks after install. Does this mean my mass air flow sensor is going to fail soon?

I've researched the heck out of P0401.... I have an 04' F250 w/a 6.0, 61k miles, completely stock. I have been getting a reoccurring P0401 EGR flow CEL. I've checked all the fittings and tubes and see no cracks or breaks. I've checked the exhaust system and no signs of leaking soot anywhere except on the passenger side exhaust manifold, there is some minor deposits of soot near the first two cylinders, but that's it.
Everything else looks good and I can't hear any hissing either. I am not getting any white smoke from the exhaust. I pulled my EGR valve and looked at it, it looked fine. I cleaned it off and put it back in. Then I got a new one just to see if that fixed it. I am missing a little coolant. I'm adding maybe a few cups of coolant every few weeks. Truck is always serviced and only repairs was Ford replaced the EGR valve in 2008. When I pull my EGR valve, it is slightly moist in the housing but not wet and no sludge. Again, the EGR valve had a nice layer of soot, no build up or sludge on it....

6.0 diesel 83,000 miles. My CEL is always on and my Edge gauge says it's lower than expected Mass air flow. I've changed the filter, cleaned the MAF with special cleaner and then replaced with new. I've replaced the EGR valve.
If I clear the codes and run it I don't get a CEL until I turn it off. But the next time I start it, there it is again. My Edge reads 0.0-0.3 MAF while running but what that means. One end of my cleaner box is slightly warped but I can't feel any noticeable leakage.
Everything runs fine but I would like to regain the ability to have that idiot light available to tell me if I have a new problem.

I just bought a set of 2013 20" rims for my 2012 F-250. I can't seem to get the tire fault light to go off. I've gone through the "learn" process but it won't read them. Are the TPMS not the same between years?

CEL came on today on my 2011 F-250 6.7 with 48K miles. It did not show a message or shut down. When I checked the code it was P2479 EGT Out of Range Bank 1 Sensor 2. I was reading about a letter last year, which I did not receive, concerning an extended warranty. My questions are: What is the part number? How are they identified and located in the exhaust system? I found a diagram stating: EGT 12, 14 ect? How does that correlate to Bank & Sensor?

I got a 2006 F250 6.0 that won't start. It turns over perfectly. What I've done so far was change oil and filter, along with fuel filters. All fuses and relays are fine. I payed for the scan gauge 2 and monitored FICM SYNC, FICM voltage, ICP, AND IPR. Every thing checks out besides ICP. The ICP is reading under 400. So I unplugged the ICP. Still no start.
I decided to spray some starter fluid in the intake and turn her over. Boom starts right up and runs fine. I even drove her around for about 20 min. I get home and shut off the truck. wait a few minutes and nothing dead again. So ICP is low but the truck runs fine after some initial support from starter fluid. What I need to do next? I don't want to have to take it into the shop for something stupid I could do myself.
Also the code its throwing at me is P0231 Fuel Pump Secondary Circuit

I have a 2007 f250 and got a check engine code icp circuit intermittent and to what I know icp sensor should be on the valve cover on the passenger side but it's not I bought the truck few months ago could it be that they swapped the engine for an early 6.0 or is there any other place for the icp sensor???

I just bought a 2016 F250 with the diesel and thought I'd share an early ownership experience. At about the 1300 mile mark the check engine light came on and other than the remote start not working the truck continued to run great. I pulled a P0170 code, Fuel Trim Bank 1. And since the truck was still running fine, I considered clearing the code and see if it would come back. But since it's under warranty I decided to bring it to the dealer. They checked it out and diagnosed a bad Fuel Rail Pressure (FRP) sensor. They swapped it out and it seems to be good to go (no more light). While I was in there I asked them to turn on the DPF percentage full screen which they did.

06 6.0 F250 throwing code P0677 #7 glow plug circuit module. I don't think one bad plug would cause a no start, however coupled with too much oil possibly? Swapped my oil about 500 miles ago, I put in 20qts accidentally, drained off about 3-4 qts eyeballed, truck fired up and ran fine no smoke nothing. Yesterday morning I was leaving work and moved my truck from parking space to behind the bay at my fire station, I turned the engine off.
Loaded up my gear and turned the engine to the aux position and someone was talking to me so inlet it sit for a while in the auxiliary position. Went to crank no start, turned the key off then back on and it fired. Fast forward after 7 different starts throughout the day, I'm at dinner with my son we go to leave engine will not start at all, rolls and rolls and rolls nothing. Towed her home and scratching my head. Over filled oil with a bad plug cause no start??
Egr delete, new oil cooler, cat and muffler delete, upgraded Y turbo pipe. Also have an SCII throwing codes p0677 and p0401 egr code....

I've done some searching on this site and found some good information but I still have some questions about Fuel Pressure and fuel flow. A few months back when I had a bad injector and bubble tested to verify and it took around 15 seconds to fill the bowl(filter removed) from near empty is that normal or the sign of a healthy HFCM?
Tonight I was able to check the fuel pressure for the first time and when I turned the key on fuel pressure was slow to build for 2-3 seconds held at 20 psi then spiked up to 62psi and stayed at that psi during the starting cycle and held steady during idle. Is it acceptable to hesitate with a pressure build at the beginning of the cycle?

I changed out my fuel filters today on my 2016 F350 SD and right parts, no leakes, main filter full, and I did the 6 cycle fuel pump prime. Turns over but won't Start. Redid the 6 cycle prime several times now and still no start. Pulled the 2ndary filter lines while it was priming to see if flowing and got squirted on both lines.

Coolant flow seems to be not at its max output seems like it's blocked somewhere. Lots of pressure in bypass line of radiator after clamping of hose and releasing pressure of degas bottle?

I have a 2004 F250. Owned it for a little less than 4 miles (186k on the odometer) .. The other day making a routine run and the radio goes out. Stopped to check it out and found I had no power windows either.
Made it home, checked the fuse on the radio and its good and the the power window fuse is also good. Put a meter on the terminals and have no voltage going to them. What I need to look at???
