Ford 6.0L Power Stroke Diesel :: 2004 - CEL On With No Codes - Erratic Readings - EGR Valve Stuck?
Feb 17, 2015
I have late 2004 with 130k with a bpd egr cooler and new oil cooler and new ficm from Ed. Cat delete with no muffler. Everything else is stock I have a dash boss and was noticing some weird numbers. My check engine light came on but I couldn't get any codes with the dashboss. I started monitoring the egr error and saw some erratic readings really high negative numbers after I let the throttle off. The truck runs okay but was kinda starting slow. Could my egr valve be stuck? Could my short modified exhaust be messing things up?

I have an early 04, I'm not sure if there's a different in pressure over the years. But I'm curious what normal or average readings are. Btw I did replace the icp and pig tail last year. Here is what I have in psi from my sct
Cold start at idle 680 .23v
Warm idle 635 .24v
Cruising 1800rpms about 1500 .32v
WOT about 4200 .78v

I have a 04 CC F250 6.0. Lately my EOT and ECT have been all over the place the ECT has been fluctuating more than the EOT. For the past 100K miles my deltas have been within the 15 degree range. The ECT will vary up to 25 degrees from the EOT; EOT may be 180 and ECT 155. I purchased a new water temp sensor thinking that was the culprit, but haven't replaced it yet. I am using a scanguageII to monitor engine parameters. I have noticed when starting the truck in the morning the temps seem to be stored from the previous night, ex. ambient temp is 75 and SGII shows 90 then comes down to match the ambient temps. For the past few days I have been noticing the truck runs and starts smoothly until I get up to 50 mph, when cold, then starts to develop a miss until it reaches operating temps. Once reaching operating temp the truck runs smooth. Could the ECT sensor cause this or is there something else going on, missing at hwy speeds until warmed up?

My son is joining the site as we try to diagnose his first diesel. We checked fuel flow, and the bubble test. We held the valve down in the oil filter and watched it fill up in about 10 seconds and see it register on the dash gauge.
My Scan Gauge say it pushes 180 RPM while cranking, but it only gets about 225 on the ICP sensor and the IPR instantly maxes out at 84. It has thrown a code P2623 for a stuck IPR valve.
I hear a hiccup in the crank, but I'll let y'all listen and tell me. Will post YouTube link of it.
What are the chances of it being just a hole in the IPR screen or bad valve? I'm afraid we have a HP leak and need to do the air test to find it. I've never done that test and barely hear (rock concerts), my son hears but doesn't know what to listen for.

Bought truck for cheaper price with no 3rd gear. Went to a reputable yard and picked up a cheaper trans... It was carfaxed with 185K miles and in a rollover. (This is the last time I try to save a couple bucks by getting a cheaper transmission.)
I believe trans is stuck in 3rd gear...Takes off slow. RPMs do not drop..Doesn't shift...Feels like I'm in 3rd from takeoff. Here are the codes:
P2262: Turbo / Super Charger Boost Pressure Not Detected Mechanical
P2614: Camshaft position signal output circuit / open
P2262 again
P1000 On board diagnostics II Monitor / drive cycle test not complete
P0678 Cylinder 8 glow plug circuit
P0672 cylinder 2 glow plug circuit
P0603 Internal control module keep alive memory malfunction
P0720 output shaft speed sensor circuit
B1676 Battery pack voltage out of range
B1318 Battery voltage low

Live data readings dropping to zero while hooked up with AE. They drop to 0 and come back but it's pretty annoying. Not sure if it's my old laptop or the actual program itself.

I have replaced hpop, lpop gears and cover, stand pipes, dummy plugs, rebuilt high pressure rails, and i still have issues. The icp readings on torque pro are mostly below 100 hot. I am clueless... I ordered the icp air fitting but it wont be here until tuesday.

My '04 F250 6.0L has 220k on it. I've had the EGR serviced several times and, unfortunately, the intake manifold boiled out in one of those services.
The engine light is on now and I've got "EGR Performance Problems" just below 2000RPM most of the time but not all of the time (runs better when warmed up)
I've been unemployed for quite sometime so I'm going to have to make this fix myself.
First question, of course, is should I plan to clean or replace the valve?
The second is how to clean the manifold chambers (? right word? The carbon accessible when the EGR is removed. I've seen people on YouTube scraping them with what looks like brake tools. Is there an appropriate tool or chemical?
The third question is is it going to be very difficult removing an EGR valve that may have carbon buildup on it? Too difficult for an aging seldom mechanic to think about tackling?
I guess those are good starter questions. I didn't know until today that EGR cooler may also be part of the problem. Unlike many of the people who post here, I have not kept good repair records. I don't know when I last had my EGR valve replaced at the Ford dealership but it was probably 50,000 miles ago.

I have an oil leak on a 04 f250 6.0 stock. It has 292000 miles on her. It started as a few drips on the pavement about the size of a quarter and now has escalated to a steady trickle. It's on the driver's side in front of engine running down the corner of the block and dripping off the oil pan. I pulled intake plenum and everything and I thought it was coming out of the valve cover but now it looks like its just under the valve cover. It looks like its coming out of the front corner of the head. Its wet there and looks wet around the glow plugs. I cant run it now as I've drained the oil and coolant. I don't have a gauge or anything and its plain stock.

ok i have a 2004 6.0 that has been a pain for the last 3 months so much so that i have replaced all the injectors,fuel pump ,water pump ,ficm, batterys , now 4 days ago i was driving and the truck stumbled for a second but i brushed it off as maybe I still had air in the fuel and the truck drove as it should .. now fast forward 2 days and whil driving it just died so I put the shifter in nutral and it fired right up in 2 seconds then it runs as it should for about 10 minuets then it died again and fired right up .. while i was turning around it died 3 more times but would crank and run then just 3 miles from home it died and would not crank . when I got the truck home I hooked up my computer and had a cam position sensor code so it sat for about 3 hours and as luck would have it it fired back up and run fine i once again checked it and the same code was there now its today and I once again fired up the truck and i checked every wire for chafing and I could not find any i even checked it while running and nothing so I drove all over the yard and the truck run great until it reached a temp of 191 at which time it shuttered and died I could crank iit back up then it would die again but now I have no codes and my icp and irp seem fine here is a screen shot while the truck is running.

A while back my 05' f350 6.0 was having rough starts and an erratic idle. It died coming up to a stop sign it started back up after 2 cranks and then it did that same on the way home. The next day leaving work it wouldn't start. I knew i had a couple injectors on the way out so i decided it was time to replace all 8 upon tearing it down i noticed my oil cooler was leaking so i figured it was time to rebuild that and finally do the egr delete that i had been wanting to do. well i put it all back together and got a no start.
The dash gauge on my oil pressure is reading normal when i cranked it so i went and bought a scangauge2 to read the icp its hitting 1500psi when i crank it. The ipr% is reading good. But my ficm main power is at 26v with the key on then it drop to 14v while cranking and eventually down to about 9v. Its never at the 48v that its suppose to be at. The scan gauge is also showing that my ficm sync=0. Would the sync be showing 0 since the ficm is bad? My batteries are fully charged and i have both of them on the charger while I am cranking it.

I've got a 2004 6.0 4x4 broke down in Gillette WY that will crank but won't start. We've had a cert. Ford mechanic bring out the computer first time it showed the IPR valve so that was replaced. Now it's not throwing any codes. We had it running for about 2 hours a week ago but the next morning it wouldn't start again. We're at a loss of what else to check. Here's what we've checked & replaced so far:
2 new batteries
New ICP Sensor
New IPR Valve
New #6 Injector
New Cam Sensor
Checked all fuses and relays
Oil is good
Coolant is good.
High pressure fuel test checked ficm 48 volts as it should be.
It's not the hpop because oil pressure stays up when cranking for fifteen seconds.
Cleaned secondary filter housing.
All filters are good.
Checked fuel pump it's good. ....

I just bought an early 04 (01/04) and it starts hard when it's cold. It starts just fine when it's warm. It idles a little rough it seems and it's putting out white smoke, but not too thick. There are no codes on the truck.
I performed the "bubble test" and got no bubbles at all. I have found that it is common for oil rail o rings and dummy plugs go bad and I'm being told that is what the problem is.
Could the oil rail seals be the problem? It makes sense to me only because there are no codes and I feel anything else would have thrown a code.

I have a 2004 F250 I just had a Ford transmission out in it. when the truck is cold it runs great. buy when it gets warm it gets stuck in a gear, even if I drop it into a lower gear. Also, if I cut it off when this happens and i cut it off it will not turn over as if it's not in gear, in park or neutral, but if I let it sit for about 20 minutes it will turn over and run as it should until it warms up again.

On my '91 last week I was driving on the highway about 60-65 when all of a sudden the speedo dial started climbing to 70-75-80-85 and past. The odometer seems to be working ok? Still when I drive it still operates in the same manner. It never bounces around or falls back. The needle is sort of stable such if I maintain a speed the speedo will maintain even though it's incorrect. There is a slight wavering of the needle meaning it's not as stable as it use to be. With the odometer working I was wondering and don't know. Does the cable drive the needle or is it electrically controlled? I'm thinking of grabbing another instrument cluster it that is the problem, I'd like to know more about it and understand how it works so I don't just throw parts at it until it's fixed.

The bolt that holds the dipstick on the valve cover. i have tried for ever to get this thing off. soaked it , got a skinny wrench on the nut underneath but think it might be stripped (1/2 inch grinded out a little). going to try and get a set of skinny wrenches tomorrow , mine bent. tried vise grips on top of the bolt and put a box wrench on the nut , and gave it my all. The damn thing won't budge.
Also, any tips on the rest of the valve cover bolts. I had to remove some from inside the fender well but barely got to them. My question is not getting these out but getting them back in. And how the heck to you torque these things??? The bolt i mentioned above is creating problem, and I only have so much time

If the fuel relief valve is stuck open would it possibly throw a P1316 code?

So I've been chasing a problem in my 07 6.0 for about 6 months now I had just changed the oil cooler and a week later was driving home and she quit a mile from my house I have since then changed the cmp sensor the alternator 3 injectors all the o-rings in the nipples of my oil rail both down tubes in the oil rail and the IPR valve most resently and last night I hooked it up to me auto engenuity scanner and the IPR valve is still not closing it stay at 14.84% the whole time I'm cranking. The only code I'm running is cmp sensor low a cuircut or something like that I can't remember the number.

From what I understand it should be dry where the valve goes. I would call it moist not wet but fairly moist. The top groove had the most wetness, the middle groove was dry and the bottom was nearly dry. Where do I go from here - the video I watched said to scrape out and vacuum - not dry enough.

My friend attended a powerstroke diesel class last week. During the class the person doing it mentioned that if you are going to do a EGR delete on a 6.0 you need to install a blow off valve. He said that the 6.0 will open the EGR valve if you over boost and since you deleted the EGR it will lift the heads. He said that the unision ring wears out which will cause the truck to over boost causing the over boost situation.

I tugged on the little hose on the back pass. side of the engine,(5.4),...
and I could hear the vacuum leak that is apparently causing the erratic idle, and PO171 & PO174 to come up.
I know this hose is hooked to the Charge motion Control Valve on the back of the manifold,..I can't imagine what it does, as it terminates with some kind of plug or check valve??? Haynes say's to remove the entire manifold to get to the CMCV.
I can see it with a mirror,. I am thinking maybe long needle nose from Harbor freight,...bend the tip short,..maybe be able to change it out?????
