Ford 6.7L Power Stroke Diesel :: Loud Squealing Noise / Exhaust TC Blew Or Fell Out?
On my way home from picking up or new Voltage 5er, I could hear a loud squealing noise when we pulled up to the house. After crawling around the under side of the truck I found the last exhaust thermal couple had either blew out or just fell out.

Truck = 2011 F250 150,000 miles, no modifications, stock.
Truck lost power yesterday, no boost, and no codes. When driving on Friday, I started moving from a red light. The truck seemed very sluggish. Then I noticed it downshift going up a small hill that it never downshifts before. I looked, and noticed the turbo gauge at 0, no boost. I pulled over, turned it off, then restarted it, but still no boost, and the truck is very under-powered. I looked over the area, and do not notice any leaks, also no leaks underneath. I hooked up my OBD reader, and no codes., the boost gauge is on zero, and the truck has lost significant power. I no longer hear the turbo spooling.
I have spent the past several hours searching sites and forums (Started with FTE ), and it seems that most believe a restart of the truck has solved it for them. However, this is not the case for me, a restart, even after letting it sit overnight did not resolve the issue.
I did see one reference that replacing a NOX sensor solved their problem. This brings up some interesting truck history. Back in June 2017, my truck threw the following codes, P207F and P20EE.
P207F - Reductant Quality Performance
P20EE - SCR NOx Catalyst Efficiency Below Threshold (Bank 1)
The message said I have 200 miles until reduced power. Since it was a Friday, not much I could do at the time so I let it sit overnight, and then the next morning the message was gone. I plugged in the OBD reader and cleared the only remaining code (P20EE), and its been a very happy truck until yesterday.
So my question, can a bad NOX sensor cause the issue of loss of turbo boost, with no codes? Is there another possible cause?
Ford 6.0L Power Stroke Diesel :: Black Smoke / Low Boost / Loud Hiss - Code P0299
Last night when I was towing my son's Ranger home - somebody stole all his gas & he thought the fuel pump quit - heard a pop and the truck started running like crap. Thought I had blown the CAC boot loose but that wasn't the case. As it turns out, the tube for the EBP sensor came off from the manifold.
I had taken it loose about a year ago to clean it out. I guess I didn't tighten it well enough. Truck blew black smoke, lost boost, and filled the cab with exhaust fumes. Easy enough fix, kind of hard to diagnose because that's not expected. Just throwing it out the for somebody's future search.
Ford 6.7L Power Stroke Diesel :: 2011 - Max Boost Rating On A Stock Turbo
Just wondering, what the max boost rating on a stock turbo, stock engine in a 2011 is. I know the gauge goes up to 40 PSI, but I don't think I've ever seen my go past 20.

Under light acceleration without any load. The motor backfired through the intake. Lost all boost. Other than the backfire noise the motor seems to be fine except for lack of power due to no boost. The motor has been serviced by Ford Dealer since new. All services have been done at 5K mile intervals. The last service was done at 60K miles. All filters had been changed at that time (oil, air and fuel).
I do have experience with turbo/ supercharged motors. My experience would tell me that the problem was with a lean condition at the time of the backfire. Plenty of fuel in the tank and no low fuel pressure warning. I have seen low fuel pressure warning in the past but it happened during the winter when temps were negative 40 degrees. The truck is still under extended warranty so I really don't have concerns regarding repair costs.
Ford 6.7L Power Stroke Diesel :: Squealing Noise Before Start Up
Just noticed a loud squealing sound coming from the engine area before I start the truck, but with the key in the on position. I'll try to get a video the next time it happens. I assume it's something starting/warming up, but it's louder than anything I've ever noticed. It lasts probably 20 seconds.

I have a 2011 F350 6.7 cclb 4wd dually. 212k ... I have the dtc p0284. The run good at idle and driving. I use it to pull a 40ft enclosed trailer. I have noticed that the boost gauge peaks at the half way mark and slowly drops half way down. I can feel my truck lose power when that happens. I also noticed that it runs alot better at night than the day. I have not modified anything except a s&b cold air intake. I have the #8injector replaced.
View 2 RepliesFord 6.7L Power Stroke Diesel :: 2013 - Turbo Noise - Loosing Boost Over And Over Again
I have a 2013 F350. Since it was new in August the turbo has made a chattering sound that sounds to me like the waste gate (if it had one) is opening and closing rapidly. Almost like its building boost and dumping it over and over again. Usually happens when it is in 6th gear around 1700 rpm under light load. It also does it from time to time while plowing snow. You can power through it or let off and it will go away. My local dealer where it was bought new put a new turbo on it and the problem still persists. The truck just turned over 8k miles and has been in several times in attempt to resolve the issue. They say that there are no codes on the truck nor does Ford have anything on their service web. My dealer claims that no one has ever had the issue.
View 14 RepliesFord 6.7L Power Stroke Diesel :: Fuel Filter / Pump Started Squealing And Making Vibrating Noise
Well, I last summer my fuel filter/ pump started squealing, and making vibrating noise, replaced the fuel filter changed the noise slightly, some times it would go away, sometimes the line going to the filter under the hood would vibrate, couple weeks ago truck warning light came on- "low fuel pressure warning" came on, hum... went out, came on a couple days later, then finally put me into limp mode, luckly only 1/2 mile from home... checked filter on frame/ tightness, it was tight, the pump on the filter housing was very noisey still, well, I figured 200 dollars cheaper than taking to ford....
I waited and pump arrived 3 days later, replaced it and low pressure warning still on, but pump was very quiet, and when I restarted low pressure warning and reduced power came on in driveway, hum.... I thought code was still in computer, I disconnected battery and turned headlights on to try and kill the code, started it and now the engine light came on, nothing else, and truck ran fine....hum.... went to autozone, and they pulled the code, low fuel rail pressure, p0087, guy said to drive and code should go off, truck runs fine. Drove truck a couple days and engine light went off, Truck runs great.......All is good.
Ford 6.7L Power Stroke Diesel :: 2011 F250 - Fuel Pump Is Humming Really Loud?
I just recently bought a 2011 powerstroke f250 and while running I can hear the fuel pump humming pretty loud. Is this a possibility that it's going out? Or is this normal?
View 3 RepliesFord 6.7L Power Stroke Diesel :: Truck Making A Lot Of Noise When Tried To Accelerate - Boost Gauge On Dash Stuck At 35 PSI
Was driving back home from shopping tonight and my truck was making a lot of noise when I tried to accelerate. I noticed the boost gauge on the dash was stuck at 35psi but the MiniMaxx showed 0psi.
No engine light so I babied it home which was about 30mins driving and managed to accelerate slowly to avoid the engine rattling. I didn't want to shut it down and restart in case it wouldn't start again for some reason.
When I got home I idled until EGT was <300F like I normally do (it never went over 700F when I was driving home) and then restarted it. The gauges worked fine, MiniMax showed boost and the engine revved freely with no rattling noise. I haven't taken it out for a road test, I'll do that when it's daylight.
Bad sensor somewhere? I would think if the turbo had failed it wouldn't have been fine after a restart.
Ford 6.0L Power Stroke Diesel :: Loud Ticking Noise Behind The Glove Box
The code was P040 which said is for the EGR system so I removed the EGR valve. It was completely plugged in the top section. I cleaned it out and cleaned out the ends of the EGR coolers then vacuumed the port out and reinstalled the valve and removed battery cables for 2 minutes to remove old check engine light codes . I drove it for 50 miles and it runs fine now and the check engine light did not come on. It still has a loud ticking noise behind the glove box which I read can be the blend door relay so I will try to pinpoint exactly what is making the noise as soon as I figure out how to get the glove box door off.

How do you diagnose a bad fan clutch? When driving in tow/haul mode I get a noise like a jet engine. It starts going down grade or upgrade and does not stop after leveling out. I have switched off tow/haul and it is still there. Over on the Diesel Stop site I found a couple of guys who have had the same problem. Concern is everything I have read there are no codes thrown. Have not taken to my local Ford Dealer to see what they say.
Driving a 2011 F-250, August 2010 build date with 76,500 miles. Problem started about 6 weeks ago when pulling an 8000 lb travel trailer in the White Mountains of NH.
Ford 6.0L Power Stroke Diesel :: 2003 - Fan Making Loud Noise Suddenly
I have a 2003 F250 6.0l 4x4 with 230k miles. All of a sudden it seems that the fan is very very loud and there may be a very little lost of power. Also i just replaced the fan clutch not sure if that may have anything to do with it. What could it be. I need to get this fixed this week...

AC compressor makes a loud growling noise and lugs the engine briefly when engaged at idle and the truck has been sitting for weeks. After that initial grind, it works perfectly and makes no harsh noises. Can I replace the compressor bearing or should I swap out the entire compressor?

My 2011 6.7 just started making a hum noise after shutdown. I've read that it might be the wastegate solenoid. Is there a TSB for this. My truck is tuned so hopefully my dealer will be tuner friendly.
View 14 RepliesFord 6.7L Power Stroke Diesel :: 2011 - Clunking Noise While In 4x4
My 2011 SD started clunking while in 4x4 this weekend. I was on an icy road for about 120 km driving about 60-80 kph and once or twice noticed a random clunk. Didn't think much of it.
Fast forward to following day - get truck on an icy hill where I had to make a sharp turn. Put truck in 4x4, turn off ATC by holding button 8 seconds. Only rear wheels engage. So then try 4 LO. Same thing. Straighten wheels, shift to park, engage 4x4 again and she hooks up and drives out no problem. Further down the road (still in 4x4), it fish tails slightly and then check 4x4 light comes on. In order to get 4x4 re-engaged (was spinning at a stop light on a slight incline) I had to shut truck off and restart it. Then it seemed to work normal and light went off.
Little further down the road I had to go up a steep incline and at a steady 40-50 kph I started hearing (and feeling) a noticeable clunk every few hundred feet. Seems to be coming from rear of truck but honestly cannot say for sure. Goes away when in 2wd.
I have 7000 kms left before warranty expires luckily.
Ford 6.7L Power Stroke Diesel :: 2011 F350 - Losing Power - Rough Noise - Vibrating?
2011 F350 diesel with 10,000 miles. I have been experiencing problems with the truck loosing power, making rough running noise (pinging like an older diesel), and vibrating. As though the motor is bogging down. It usually occurs on small inclines or hills with the truck in higher gears and low rpms. It will also occur running on flat ground 65-70 mph. Had it occur once while turning the truck around in 1st gear and low rpms. Depressing the accelerator will bring the truck out of it.
This problem occurs randomly sometimes a couple of times a week to not at all. Took to dealer and they found no codes and of couse it didn't do it on the hour long test drive I took the mechanic on. However they did say they had two other owners come in with the same complaints, but could not get trucks to repeat the issue. Problem usually occurs in the hotter part of the day, maybe just coincidence. I had seen similar posts with this problem but no conclusions.
Ford 6.7L Power Stroke Diesel :: 2011 F350 - Whistling Noise At 75 MPH
I've got a 2011 F350 Lariat crew cab and when i get up to 75 mph with a cross wind, there is a whistling noise. it sounds like a turbulent whistle as if its blowing across the ribbed portion down by the wipers. I tried to get audio but for some reason my phone wont pick up the noise, but its extremely loud at times. Sometimes it will wake up the kids if they're napping in the back seat.
