Ford 6.7L Power Stroke Diesel :: Engine Shut Down Descending A Steep Grade
I do not think, I have seen anything about the engine shutting down descending a steep grade. first it threw the "wrench" warning and than that the engine was going on limp mode. luckily no one was on the road with me, coming or going. i pulled off on the shoulder with part of the pickup and 5er on the road. no steering or brakes used the 5er brakes to stop. turned the key off and restarted it again and no code or warnings. like nothing happened. it happened twice today between yellowstone park and great falls, mt. the second time the engine light stayed on and i had to stop and turn it off and restart it and it went away.

Well, my saga continues on my intermittent AC problem on my 99 f350 v10. As before, the AC blows cold but mysteriously stops working on occasion when climbing a grade or stopping at a light in warm weather. I bought a gage kit and runs ~ 45/250psi on the low/high gauges. Clutch is stopping and the metal tube from the accumulator tank runs warm when this occurs.
Seems like the problem occurs when the under hood temp reaches a certain level. Thought it might have been one of the switches but the pressure seems to be OK when these problems are occurring. What/how to check to find the problem? some of my thoughts are:
1. Wire a light in the clutch engagement circuit to see if the problem is in the compressor clutch coil not working when powered up or some heat related failure of the wiring continuity.
2. Check the Hi and low pressure switches for continuity when this is happening. to do this I need to know a few things- location of the high pressure switch low press in on the accumulator) and whether the switch should be open or closed in normal operation. Also can the switches be replaced without losing the charge in the system?
Ford 6.0L Power Stroke Diesel :: Wrench Light Comes On Pulling Even A Light Load Up A Grade
The thing is the truck seems to run fine. But, when it hits 30 pounds of boost it goes in to limp mode. Good way to get yourself run over on a highway. I'm wondering if the computer or whatever has gotten off somehow and is sensing a problem too early ? Would a re-flash possibly correct this ? BTW, it is a 2005 with 63,000 miles.

Decided to try a new wheel to see if I can stop the surge during hill climbing with our 5er. Old wheel looked great with no dusting or nicks. New wheel sure has a whirl when it spools up, but sounds cool. Haven't pulled trailer since swap yet. Truck still only has 85k on the clock.

Truck has been running very well while in the warmer North Carolina climate pulling trailers with no limp mode or wrench light. However, when daughter started the truck this morning, SGII showed one DTC and when she pulled it up it was P0675. OK, glow plug num 5 maybe or the module. No issues starting or rough cold idle. I told her to clear the code and we'll see if comes back.
She did ask if it is something she should have it repaired before the trip back to Vermont. So I thought I'd ping the group here since reading posts, they seem to be fairly easy to replace (and assuming it isn't a chafed wire) and I could probably save her some $. Just want to make sure there isn't any chance of real engine damage.
Ford 6.7L Power Stroke Diesel :: CEL Code P02E1 - Diesel Intake Air Flow Control Performance
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.
Ford 7.3L Power Stroke (1999-2003) :: Slight Pinging Sound At Low RPM When Climbing A Steep Hill
Was climbing a steep hill at 35 mph just before truck down shifted to 2nd, I was hearing a pinging sound. Sounded like only I cylinder was doing so. What it could be. I am currently running a 1/4 tank of Fppf fuel injector cleaner. Is this a injector noise. No knocking just a slight pinging.
View 1 RepliesFord 6.7L Power Stroke Diesel :: P259F Code / Reduced Power Mode
It happened to me. I was 2 hours into my trip and towing the camper when I got the reduced power CEL. I have 28,000 miles on my truck and always tow in "tow/haul" mode with the exhaust brake on. I was lucky in that I has on a limited access highway and just happened to be approaching an exit to a fuel station with big rig access. I limped in there at about 20MPH checked the code with my Forscan lite and found the P259F code. I typed that into Google and found a thread on another Diesel forum! Some guys said it went away after 3 or 4 restarts. So, I tried a couple of restarts...no luck.
I was down to half a tank of fuel so I filled up and parked. As long as I was parked, I went into the camper and used the bathroom. When I got back in the truck, I thought about the WiFi scan adapter plugged into my OBDII connector and wondered if I should unplug it. I did and everything worked! So, I drove the next 4 hours in "tow/haul" mode, but I left the EB off. I also never plugged in the WiFi scan adapter because I didn't want to risk going into the reduced power mode again. Anyway, we made it home without incident. One of the reasons I traded my 2013 in on a 2015 was to get the engine improvements and the EB. I sure don't want to give up the EB. I'm going to take mine to the dealer, but after reading this post, I'm not expecting anything much.
Ford 6.7L Power Stroke Diesel :: Significant Reduction In Power - CEL And Code P208E
Got this nugget this morning after dropping my daughter off at school. I also noticed a significant reduction in power. Had to get fuel so while pumping, I checked the code with my WiFi reader and Engine Link app.
Got the code number which came up with this: 6.7L ? MIL on with DTCs P208E P218F P204F ? 2011-2016 Ford F-Super Duty
I decided to clear the code and see if it would instantly return which it didn't. Power came back as soon as it was cleared too. Will see if it comes back. Looks like the code is saying there might be crystals on my DEF injector. I did have a regen last night right before I parked for the evening and then this showed showed up first thing this morning. Would a DEF injector nozzle be covered under the emissions warranty if it comes back?
Ford 6.0L Power Stroke Diesel :: Code P2290 - Start But No Power
Long story behind it but finally got my scanner working right and checked the suggested systems for p2290.
IPR was 77+ on start up dropped to around 31 at idle
FMP is in the 46.5 to 47.5 range
SYC was at 1 and occasionally at 1.5
ICP was at 550-650 during startup and quickly ramped up to 1150 then settled into around 850 at idle.
The only thing that I'm not sure of is the IPR being 31 at idle, is that what it should be. The others I think are within normal operating parameters.
The truck starts but has no power. Can barely go up a slight hill on my street. Seems like it's going to be fine but as soon as I apply a little gas it just falls off.
Ford 6.0L Power Stroke Diesel :: Low Power Until Warms Up - P0234 Code

View 3 RepliesFord 6.7L Power Stroke Diesel :: Reduced Engine Power Message - Code P164A
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.
Ford 6.7L Power Stroke Diesel :: Got Code P0170 - Power Fuel Trim (Bank 1)
Drove the truck to the store tonight about 5 minutes away and everything seemed fine. Went to leave the parking lot and noticed the check engine light was on. Pulled out my tablet, dongle and fired up Torque Pro. Retrieved error code P0170. Truck has a little over 12,700 miles and is complete stock. I ran a search and didn't come up with much info on this code other than what Just Stroken posted in another post.

Ford 6.7L Power Stroke Diesel :: Power Loss - Code P0401 - EGR Cooler Is Clogged
My 2011 has 62k miles and has been throwing P0401 codes, which results in losing power. I assume the EGR cooler is clogged. So I went to the dealership to see if it's covered, and was told there's no warranty coverage.
I would rather blockoff the EGR cooler than repair it. I would also like the extra performance from a tuner like the MiniMaxx. I do prefer the stock exhaust and not real excited about the drone/smell that comes with deleted DPF.
Will I have issues if it's tuned with the EGR blocked off, and stock exhaust? Or am I better off doing a full delete at this point?
Ford 6.7L Power Stroke Diesel :: 2011 F350 - Reduced Engine Power Code On Dashboard
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...
Ford 6.7L Power Stroke Diesel :: CEL With Code P00BC?
I recently put on my no limits intake and have started getting a check engine light for code P00BC which means P00BC - Mass or Volume Air Flow A Circuit Range/Performance - Air Flow Too Low. It comes at random times and I can not recreate it. Does not effect the driving of the truck. At first I thought it was the tunning but I got custom tunes and it happened again today. Is it possible that it just got dirty and needs to be cleaned?
View 14 RepliesFord 6.0L Power Stroke Diesel :: CEL On With Code PO299?
i had a very bad day yesterday after loading my families atvs on our trailer and heading 40 miles away the 6.0 let me down. the check engine light was on about a month ago but the truck was running perfectly so i unhooked the batteries and reset it and the cel had not been back on until the start of our journey yesterday. the cel came on and the turbo barked and then every time i hit the throttle i had no boost till about 2500 rpm then the boost would go up to 30-33 psi only going 60 mph. so after making it to the trails and making it home i took it to advanced auto to read the cel codes and they pulled the po299 underboost code. now i know that this has been brought up many times but i cant find any where the truck has been over boosting like mine was. and also i did check all the boots and they all seem to be fine.
I really don't want to take it to ford until i know some of the cause because the truck isn't under warranty ... Also only mods to the truck are mbrp 4 inch turbo back exhaust and afe stage 2 cai
