Ford 6.7L Power Stroke Diesel :: Reduced Engine Power Message Came Up On Dash And Truck Died
Sep 4, 2017
2015 F350 6.7L, 43,000miles
My family and I were driving into West Virginia this morning when the reduced engine power message came up on the dash and the truck died. I coasted off to the side of the road as best I could and got out. Immediately I smell diesel fuel. I look under the truck and there is fuel all over the passengers side frame and when I keyed it back up fuel started spraying down by the right front wheel.
Pulled the fender liner back and saw a small rubber hose that looks like it came off of a tee fitting down by the egr components. I tried to get it back on but wasn't able to get it seated 100% and when I tried to restart it blew off again. Truck is completely stock and ran perfect right up until it died.

I have seen this pop up on the truck I think 3 times now over the first 4000 miles on the truck.
Usually it's when I'm on the highway around 70mph or so.
It comes on for a few seconds, then goes away. I do have an exhaust / tune on the car.

I haven't had any issues with this truck before but last night I pulled out onto the highway and my check engine light came on and a message saying engine power reduced I finally got it to reset after 4 times of shutting the truck off, was wondering what this may be without knowing the code. I tried plugging my edge cts into it from my 6.0 but it wouldn't communicate guess it needs a update trucks a 15 f350 with only 30000km.....

So I just went on a vacation pulling my horse trailer (first time leaving the state with this truck) and at about 5 hrs into the trip I had a message Reduced Engine Power and went from 70 on the interstate to 10 miles an hour and slowing rather quickly. I ended up shutting it off and restarting and it came back just like normal. I found the nearest ford dealer and they put the computer on it and it showed absolutely nothing, no codes and nothing wrong. The mechanic reset some things and we went on our way.
Then I ended up getting a check engine light saturday. I found someone to read the code and it came up with P164A which is an O2 sensor, he was able to clear it and I put on probably 50 miles today and no check engine light. I have about a 10 hour drive back home. Still debating if I take it to ford near here if they will do anything now that it doesn't show a light?? I hate to chance getting broke down on the highway with a truck that will basically shut down like that?? It just doesn't make sense to me.

I started my '16 6.7 this am and drove it about a mile.
The check engine light came on and at the same time the display said "Reduced Power". I decide to turn around and try to make it back to my shop but shortly after turning around the display said "Low Fuel Pressure" and within a couple of hundred yards it shut down leaving me stranded by the side of the road.....
I called my local dealer who gave me the Ford Cares 800 number. I got a flat bed in about 1.5 hours which I didn't think was too bad considering I live in the country and they brought it to the dealer. The SA said it might be a couple of days before they could look at it as they were pretty busy... What it could be? The engine is stock with 9100 miles on it...

I have a 2011 Ford F250 6.7 Powerstroke. It has 107,000 miles on it.
The other day I was driving it down the highway and it got a Reduced Engine Power message on the dash. It lost power and I got off the highway to the service road. Then it died on me.
Had to get it pushed to a station then towed home. It wouldn't start. The starter cranks over for a few seconds but engine won't start. Checked all the fluid levels and batteries. My DEF fluid was only a half gallon low.
What I have noticed is that the DEF level indicator hasn't reminded me that it was low for over 4-5 months now. I had been putting in about 2-3 gallons every 3 months or so. But it hasn't reminded me lately and I just forgot. This is my first diesel.

So, I just had the fuel pump replaced on my '15 6.7 a month ago and it just died again. (next day edit: it didn't actually die, it showed all the same symptoms)
Same symptoms: whining sound, low fuel pressure warning, reduced power warning.
This time I'm 50 miles from home so I pulled off the road before it shut off. Interesting, I was in a hilly area and my low fuel warning came on too. We are waiting for a tow. I was considering trying to push on but don't want to get stuck in a dangerous spot on the highway. We're in a church parking lot.
So, last time this happened I was on flat road with about a half tank of fuel on a lunch break. I ran a mile after the warnings came on to feel out the issue and to see what would happen. I happened to be only about a mile away from my dealer so I drove that way. I got reduced power warning and then it cut power on me (limp mode). I made it to about 100 yards away before it cut off.
This time, I was in a hilly area at night on a windy two lane road with no shoulders in the woods. I was miles from civilization and was showing below a quarter tank of fuel. ~100 miles to EMPTY. I got the low fuel pressure warning first and then the reduced power mode before the whining noise started. I was climbing a hill on a curve at the time. I drove a quarter mile and then pulled off the road into a parking lot so I wouldn't be stuck on the shoulder. It didn't actually go into limp mode.
I let it sit a few minutes, talked it over with the wife and decided to call for a tow. After talking to the tow truck driver who said he would be an hour because he had to go find a bigger truck, I decided to see what I could do while I wait. I fired it back up and the fuel level dropped to below 1/8 and I was now showing 33 miles to EMPTY. I was parked on a hill with the back end up. I had backed the truck into a space to make it easier for the tow truck driver. I let it run a minute, checked for leaks and it seemed to run fine with no studdering or additional warning lights.
CEL was on but no new warnings. I put in my code reader and pulled the P0087. Just one code. I revved it a bit to see if there were any issues. It seemed fine so I decided to try my luck. I started driving towards home with the intention to stop at the first diesel station to fill up. Truck ran fine. After two minutes of driving gently, heart racing, my fuel level came back up and it now read 88 miles to EMPTY. I drove 11 miles to the nearest station and filled up. No issues. I shut it down. I fired it back up. Still no issues so with a full tank, I drove home the remaining 30 miles without issue.
Planning to take it in to the dealer Monday to get it checked. Could this be from an air pocked due to low fuel level and hilly terrain? Is my new pump dying already? Is there something else going on inside the tank or elsewhere?

Had just got done filling up with diesel, drove 1/4 mile and truck just died. Tried to start it and nothing. No power to edge tuner either. Fuse #22 20a under steering column blown (engine control). Replaced and keeps blowing. not sure what is causing it. Just another wrench to throw in my wedding week!

2016 F350 6.7; ccsrw, 22K on truck (zero issues previously). Stock other than titan fuel tank that was installed at 100 miles.
700 miles into todays trip, pulling trailer, snowing, in 4x4, tow/haul; pulled out to pass, got into it for a bit and got "reduced engine power" error, truck slowed, would not show boost on gauge, wouldn't rev over ~1900. CEL is on.
Pulled over, stopped, checked under/over and didn't find anything. Shut off truck, started back up, CEL is still on, but truck runs OK. Ran for another 20 miles or so and was OK for how I drove it (including boost showing on gauge). Not hot rodding, crappy road conditions (snow). Got on a big hill from dead start and got into it a bit, about 3K same error came on and she went back into limp mode. Same deal, stopped, shut off, back on, was able to keep going. Was only couple miles from motel at that point, so she is on break right now.
Of course I'm 400 miles from home and nowhere near a dealer. I have a code scanner, but nothing with me to pair it with (daughter has tablet with her, ha ha).
Should I keep going or find a dealer/tow/other? If she will keep running "normally" below 3K, then I can make it home as I don't need to horse it that bad on the roads I'll be on.
Truck has had fuel filters replaced on schedule, dealer has done all service work (oil, etc). Fuel filters were done 7500 miles ago.
This trip, was on third tank of fuel. Had just put in 30 gallons at last (big) truck stop about 15 miles before this issue happened, have 50 miles on this tank. That was 30 gallons into 50 gallon tank.

I am having a problem with a 6.7. The truck has 9900 miles on it. It has a dpf delete, egr delete, Spartan tuner and a snow stage 3 kit. The truck lopes at idle but once throttle is applied it levels out but still runs a little rough. Its keeps saying its in reduce engine power no matter how many times I clear the code. If I clear the code it will come back in 2 seconds with out cranking the truck or anything. Rail pressure is telling me 31090 psi and not changing running or not. I have changed rail pressure sensor, and pressure control valve with no result. The green and violet 5 volt reference that feeds those sensors is only putting out 1.2 volts. Put a new pcm in it still the same and now has quit running totally. The codes are P0193, P0335,and P06A6.

The truck (2012 f350 6.7 lb cc 131,600 miles) started fine. Then while i was setting up the defrost i accidentally hit the ac button. Well I then hit it again to turn off. At that point the engine stalled. Which has never happened to me before. I started it back up which took a bit longer to get it to fire. It now says "Reduced engine power" and runs kinda rough. I thought well im at the end of my fuel filters life so why not change it since i had one. Well the. The FF housing broke. After replacement FF housing and filter it will no longer start. I took the filter back off and checked to see if it was cross threaded or sucking air. I checked that twice. Still no start cranks fast and strong. Codes are
P2138 something to do with the gas pedal
P0193 fuel rail sensor A high
P06A6 voltage on circuit A is whacky (paraphrasing here)
P0532 ac pressure sensor low

Getting reduced engine power warning with no other lights on the dash and what is probably causing it. The truck is a 14 f450 cab and chassis model. I had just had it to the dealer for this problem and the check engine light was on and the said there were two sensors going bad on the exhaust so they changed them out and sent me on my way. Well after driving the truck around all day and not one issue it had just decided to set the rep warning again but did not set off any lights...

Reduced Engine Power warning and fuel leak? While towing our 37 Fiver uphill a couple of days ago, the warning popped up along with the CEL. Indeed, the truck did lose a tremendous amount of power. When I found a safe place to stop, the diesel smell was terrible. Further inspection revealed that fuel was dripping down the side of the engine from somewhere above the oil filter. I limped along another 15 miles to the campground and unloaded the 5<SUP>th</SUP> wheel and brought the truck in to the dealer this morning. They aren't giving many details of their findings thus far. They say that they've talked to Ford engineers and that they'll have to put a dye into the fuel to detect the origin of the leak. They suspect the high pressure fuel pump, but by the time they remove enough "stuff" to get to the pump, they can't run the engine to witness the leak. This is my first Ford in 30 years behind the wheel and my first diesel. After 8k miles on the truck.....

I just had my first fuel filter change (about 9,000 miles). After the shop changed both fuel filters with factory Ford ones, a check engine light came on and a "low fuel pressure" warning, along with a "reduced engine power" warning. It also stalls a lot and takes a long time to restart.
Obviously, they didn't do it right. I suppose there is air in the lines or something didn't go back together correctly.
My '06 seemed to purge itself, but this truck obviously won't. It is not even driveable to get it back to the station, to see if they can correct the problem.
The thing is, I watched them do it, so if someone can ask me the right questions as far as what I saw, maybe I can lick the issue in the driveway myself.

I have a 2011 6.7 F-350 Diesel. I bought the truck new and I've never had any problems with it until now. I have a SCT Chip & Tuner. It needed an update so I returned the truck to stock and a code came up on my dashboard that said "reduced engine power" which obviously I thought was Normal because of the modifications done to my truck.
I updated my tuner and returned the truck to a performance tune but this dashboard code will not go away. My truck isn't reading any codes and there's no other indication lights on. The truck has Normal RPM readings but 0 throttle response. No power at all...

Got a Decreased Power message across the dash info center today and was limited to only around 5lbs boost. I stopped and pulled the codes and here is what I found:
P054E - Fuel Quantity lower than expected
P1249
P1247
P0471 - Exhaust pressure sensor range/performance
P02D7 - Injector learning @ max
P0402 - EGR flow excessive detected
I dumped the trailer and limped home to change the fuel filters. I could only go 35mph on the flats and 10mph on any kind of up hill slope. I switched out the filters, purged the air, fired her up and cleared the codes, all seemed well. I backed out and went for a test lap around the neighborhood, as soon as I turned the corner and rolled on the throttle and reached 35 the message came back and the codes returned. I will be towing it in to the dealer tomorrow for diagnostics.

So the A/C compressor died on my truck. I am looking at replacing it myself and it looks rather tight in there. My labor manual says I have to pull the fan/fan clutch, fan shroud and right inner fender to gain access.

So about 3 days ago I made a long 9 hour drive. No problems at all but I did allow my fuel to get a little lower then I normally do. About eighth a tank had 30 miles left on the digital read out. Stopped and filled up at loves where I always get my fuel. And off I went drove it down to 3/4 a tank and made it to my stopping point. Got in to go about 7 miles down the road and come to a stop sign and slowing down the truck died. I thought crap I forgot to turn off the auto start but never done that before. Stopped and stared truck as normal. Made it to my stopping point again. Headed back to the house and doing on average 55mph and truck surges like it wants to die but doesn't.
Rpms drop below 500 and it keeps going I get to same stop sign and slowing down again doing maybe 25ish and truck dies again as I have my foot on the break. Put in nut and started it right up and drive on home. Today went about same distance. Only this time I started it with key and was doing down other things while letting it run it just dies start it back up and take off get to where I was going and it surged or hiccuped so to say. Again started it once I was getting ready to leave and let it run for about 5 min and it died had the heater on as it was chilly out by the lake. Got in and restarted it and it was blowing cold air and had a diesel smell to it. Wife asked me if truck was going to blow up. Backed out of area and put in drive and made it 80' or so and truck died again doing about 10mph
Checked so far
Batteries checked and both are good
No mods done to it
New ICP sensor and pigtail
New water pump
New injectors 20k miles ago
Oil changed 1100 miles ago
New filters upper sad lower

Last friday, my truck died while running. I let it sit for a few hours, went out and it started right up. Went to get pizza for my kids and I got 5 blocks from my house and I barely had any power. Truck died again while getting pizza and had to tow it home. Now it will not start. I have checked fuses, taken apart the fuel pump on the motor and cleaned the water from it, added a fuel treatment and also did an old truckers trick with the fuel (10% gasoline). the truck will crank and make an attempt to fire but it will not start. I have 3 kids and this is my ONLY transportation. I need to get this thing running STAT.
