Ford 6.0L Power Stroke Diesel :: 2004 F250 - Irregular EOT And ECT Readings
May 4, 2016
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?

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 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?

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.

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???

I have a 2004 F250 6.0 DuperDuty with about 170,000 miles on it, so far no major break-downs, just a starter and a blinker relay, but now I have a problem.
When I start now, the truck starts fine and it sounds fine, but it has almost no power even if I floor the gas peddle, there is a delay of like 2-3 seconds and then responds slowly, like some tractor. Eventually it starts to move slowly, and after it warms up (after a few minutes), the gas peddle responds more normal.
Also - at about 45mpg, at lower RPMs about 1250, the engine starts to shake (weird), it doesn't do it at idle about 850 RPM, or when I get it up to about 1800RPM+, but at about that 1250 RPM it does do it, luckily I driver locally for a few miles.
What could this be ? What exactly happens when I press on the gas peddle, what systems are involved and in which order?

I've got a 2004 F250, 6.0, with 150k miles. I was pulling a motorcycle trailer uphill in the mountains when suddenly I couldn't go over 10 to 15 mph. All the gauges read good but it just couldn't get any power.
Got to the top and checked over everything. Didn't see any issues. Drove it home (200 miles) the next day. It drove okay on highway but it felt like the turbo wasn't coming on. Coolant was low and EGR was gunked up but only slightly wet. From what I read, it sounds like EGR cooler is failing but would that cause the turbo not to come on or feel like that loss of power? Reading another thread, I thought it might be the fuel pickup but I dropped the tank and the sending unit looked very good.
I'm ready to throw on a bulletproof egr cooler, oil cooler and rebuild the turbo if necessary but hate to get to the end and find out none of that worked.

I have a 2004 F-250 with a 6.0 and am having a serious issue. The truck has about 240,000 miles and has been great until now. About a week ago the truck was running great and had plenty of power. I decided to wash it with my pressure washer (did not spray under the hood, however I did spray in the front wheel wells and underneath the truck). About 5 minutes after washing the truck, I took it out for a drive and noticed when I really got on the accelerator the truck would not want to try harder and motor got very quiet. Really all you could hear was the turbo whistling. Over this past week the problem has gradually gotten worse... a few days ago I had to feather the pedal in order to go up hills. If I gave it more than about 1/4 inch of accelerator, the motor once again would get quiet and the truck would start to slow down and would not want to work.
However, if I let up and only gave it a small amount of accelerator, the motor would sound normal again and it would pull up the hill. Today, I can do nothing more than idle back and forth in the driveway because the motor gets quiet and the turbo winds up if you give it even the slightest amount of accelerator. I have no idea if it's a coincidence that this happened after washing the truck, or if maybe there was a sensor that was rotted and about to die and I finished the job with the pressure washer. I already replaced the egr valve and have been running tons of Howes diesel conditioner and anti gel through it. The injectors were replaced about 50,000 miles ago so I'd hate to think it was them. The truck doesn't smoke at all either.

First off my vents stopped blowing completely. At this time the thermostat was still functioning. Fuse 28 was blown. I replaced the fuse and it blew again shortly after turning the heater on. I replaced the relay and resistor and still blowing fuses. For some reason I tried a 30A fuse and it didn't blow but a few minutes after turning on the heater there was a burning smell. I immediately turned it off and pulled the fuse back out, which was hot. I then replaced the blower motor and at this point there is no power at all to the control panel. The fuses are all fine as well as the relay and resistor. There's power to the fuses. So it seems like somewhere between the fuse box and the control panel I'm losing power.

While driving home the other night at highway speed my truck lost power. I just filled the tank about 15 miles before then and everything was running fine. No lights came on the dash before the truck died and now can't get it started. Bad fuel? Clogged filter?

this morning I started my 2004 f250 drove a mile and filled up my truck. Then drove another mile and my truck acted like it was running out of fuel. It was loosing power then stalled out and wouldn't start. About five hours later I tried to start it again and nothing. about five hours after that I tried it again and it started up and drove fine.
My thought was fuel filter or the water trap. I haven't had a chance to open the filters up and check them yet. Today while I was at work I got on here to see if I could figure out what was wrong with it. all I could think of was maybe the HPOP went out or the ICP sensor. Could one of these be the problem or was I right with my original thinking and it's just a fuel filter? First thing in the morning I'm going to pull the filters and replace them.
Could there be something else wrong with my truck that I don't know about? Like I said I filled up the fuel tank then it lost power within a mile and stalled out and wouldn't start back up. Then about 10 hours later it fires up and acts like nothing happened.

Ok I have an early 2004 F250. Recently changed out the #8 injector and then had to replace the ICP Sensor. Was running great then while driving down the road just died all of a sudden. Would start right back up with no issues. Continue driving and I am getting intermittent power loss. Also noticed that when it would lose power suddenly the glow plug light would come on.
Codes are P0102, P0113, P0272, and P1000.
P0102 Mass or Volume flow circuit low input
P0113 Intake Temp circuit High input
These are just soft codes not setting a light off. MAF is plugged in and I will check wiring here later after work but could this be causing my intermittent issues?

I have an 04 6.0. My truck was running perfect, no problems. I start my truck, it started idealing rough for a couple seconds then just died. After that it just kept cranking and no start. There are no codes, tried unplugging the ICP sensor and nothing. Checked the fuel filter and its filling up with fuel before cranking. Oil is at a good level. FICM is reading 46.5-47.5 before cranking. Checked the ICP Psi I'm only building 11psi and HPOP was replaced in October.

My husband and I purchased a 2004 f250 king ranch 6.0L... We love the truck, despite the headaches. We took it to a dealership and spent just under $5k in parts, drove it for a month (everything going great) until we shut it off to bs w a friend and it won't turn back on. It's been sitting for 4 days and nothing. Cranks and cranks, but won't actually start. We are pretty handy with gas trucks, but this diesel is out of our element- we are getting better though haha!
We looked on here and saw that the no start could be bc of the FICM - swapped it out- not the issue.
Now the codes being thrown are P2291 & P2285 (or so my husband says)
We are thinking if we replace the ICP and that fixes it, we won't need to do the HPOP. Or do we need to do it as well? Are we on the right track?
When we shut it off, it didn't have any lights on, no gauge fluctuations, or any "red flags". This is why we are stumped!!
(Ford dealership fixes: 2 batteries, new starter, new tank cap, new oil cooler, maybe a few others- receipts not infront of me).
Like I mentioned, we've already dropped more money than we have into this truck and now it's taking more- we love the truck and once it's fixed we will "have a new truck" it just sucks bc my husband works afternoons and I'm a stay at home mom with a 14mo and this is our only vehicle.

I'm new to diesels. I just bought a 2004 F250 with the 6.0 V8. I have the high and low circuit, contribution codes on cylinders 4 and 8. I've only had the truck for a few days but I've been reading a ton. The symptoms are hard start, rough idle/shaking, no power when cold. When it heats up and I'm over 2000 RPM it seems to be just fine. Even when hot and below 2000 RPM it does ok. I've check the FICM. It reads 48V with key on and 48V running. My plan is to do the following:
Change the Fuel Filters
Change the oil filter
Change Air Filter
Change oil with 5-W30 synth and I have both Hot Shot/Rev-X
If that doesn't work, I'll replace the two injectors. How does that sound.

I have an early 2004 F 250 6.0 that just quit one day and haven't been able to get it started since then. I have tried to follow the No Start checklist...
I have no aftermarket mods or tunes.
I have changed the fuel filters, made sure that there is fuel in the tank and made sure that it is getting fuel.
I have un-plugged the ICP and still no start.
When I turn the key on it goes through the regular sequence and I hear the injectors (sounds like it's doing a buzz test).
When I try to start it, it cranks over, but I hear a good bit of clicking coming from the fuse/relay panel under the driver's side dash.
I have inspected fuses/relay and dont see anything smokingly obvious.
I installed new batteries, but no joy.
While trying to start, it sounds like it may actually do it for a second, and then I get a noise from the starter.
I bought a scanguage and added the PIDs that I found searching through the forum and here are my results.
ICP key on = 0.23 ICP while trying to start = 1.30
ICP Voltage (Volts)
TXD: 07E02216AD
RXF: 0462451606AD
RXD: 3010
[Code] ....
Camshaft & Crankshaft Sync = This is erratic; it will flash 1 and immediately go away. The thing is, I don't know which sensor should be replaced.

The truck is a 2004 f250. Build date is 7/ 03 so its an early 04. I have been in a parking lot for 3 days now with no money trying to get this truck to start. Me and my dad replaced the ipr pigtail and the ipr thinking this might have been the problem, because the ipr pigtail had a damaged connector.
Before doing this work the icp sensor connector had no oil in it, now after replacing the ipr and cranking the engine the icp has some oil in the connector, could this cause a short and not let the truck start, and if so will unplugging the icp allow the truck to start?
We were having trouble with no starts before this happened and when it did all we had to was push the ground wire back further that goes back to the ficm and the truck would start, but that is not working anymore.
Is it possible the ipr is not seated properly or the new ipr is bad out of the box? Or maybe the made in tawain pigtail connector to the ipr is bad?
We are thinking it may be a short somewhere in the harness since everytime we pushed the ground to the ficm up further to where it grounds before when we had no start problems this might have took the short out of the ipr or icp pigtails and allowing the truck to start. Injectors are buzzing when key is turned and I can hear the fuel pump.

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.

I have a 2004 f250 6.0 factory as can be I haven't did anything to it mechanical wise but lately while driving the truck bogs down while I am driving. If I give it a little gas or get off the gas it will clear up or sometimes while I am driving if it doesn't bog down, and I am trying to accelerate the truck will start to turbo bark.
