Ford Super Duty (1999-2016) :: 2015 F250 - Check Engine Light Comes On And Truck Goes Into Limp Mode
Bought a brand new F250 6.7 it has 7000 miles in it now and the check engine light comes on and the truck goes into limp mode. I have taken it in to the dealership twice they said there is no code they can find and they just reset the check engine light and it does ok for a bit then starts the cycle all over again. It also is only getting about 6.5 mpg....

Replaced HPFP 38,000 miles ago. Truck began going in limp mode without engine light, wrench came on in dash, gave codes for brake switch, anti-theft, some other weird codes. Had those codes cleared, ran for while then water separator came on, drained the water out, came back on. Read some forums, so I removed and cleaned the housing, cleaned off the sensor. Had code cleared and ran good for about a week. Then guess what engine light comes on, limp mode.
Went to Auto Zone, pulled code P0088. This truck runs awesome until limp mode. No other problems. I take it to the ford dealer, scanner pulled P0088 and the water separator code again. I have read alot of remarks about this P0088 code. Can there be another cause for pulling this code, only 38,000 miles later. I had them do the TSB 12-07-07 but I have also read it can only be done if the P0088 is the only code. I just really feel there is an underlying issue with these 6.4's.
Ford Super Duty (1999-2016) :: Truck Keeps Throwing Communications Code And Goes Into Limp Mode
I recently bought a h&s tuner and installed a dpf delete kit. Everything works great when the truck is not plugged in to the tuner although when I do plug it in, the truck keeps throwing a communications code and goes into a limp mode until I delete the code. I believe it was p0073 but i maye be mistaken. Regardless it has to do with communicating through the obd2 port. I sent the tuner in to get checked out and it turns out its something to do with the truck. I've checked all the fuses and tried to check for broken wires. Where to look next?

F250 7.3L diesel started to flash OD light, goes into limp mode, code p1747. No other codes. Have had issues for a couple of years where the truck would not shift into gear for awhile; sometimes a couple of minutes till it would engage. Have done lots of diagnostics. Visual check harness. Have 12v on pins 1&12 on harness at transmission plug. Plug had some ATF visible, but cleaned it up and continuity good. (with 4" exhaust hard to get to connector).
Checked all solenoid wires with a DVM back to plug at PCM for continuity and shorts, all good. Pulled transmission pack and checked resistance on all solenoids except temp varistor all within specs. Removed Banks Trans Command and rewired tranny plug and pulled Ottomind chip from PCM. Still goes into limp mode and throws code. Did not see any bad solder joints or burns inside PCM by the way.
Seems like PCM right? But here is a complication to my issues. For over a year I have been having electrical issues like the radio not working and windows not working intermittently after starting up. After running for awhile or on restart would work fine. Sounds like the Instrument Cluster issues or relays.(?)
Will be pulling IC and checking for any bad solder joints. However, did not throw p1747 till just recently and now my radio has really gone wonky. It comes on when key is on automatically and then proceeds to cycle through settings; AM-FM-CD.
So questions are, "Is it possible that a bad Instrument Cluster can cause a p1747 code?" "Bad Ground to Tranny" "Can a bad PCM cause a electrical issue in IC??" "Are these 2 separate issues?"

Ford Super Duty (1999-2016) :: 2006 6.0 - Start Running Rough After 45 Seconds And Go Into Limp Mode?
Ok just bought this truck ran fine. Put a sct tuner on that the truck came with and some how got the egr turned on. It had a egr delete so it was smoking and finally found it out that it had turned on but fixed it. Now we have another problem, it will start up and run fine and about 45 seconds it will start running rough and go into a limp mode. It will run rough and starts to die slowly and when it starts to die there is no throttle at all.

My F250 with V10 has developed an overheating problem. While driving, the temp gauge suddenly shoots to max, and the truck goes into limp mode. Turning off the truck and ignition, waiting a few minutes, and all seems to be well again - sometimes for only a minute, sometimes for several days. No steam leaking, the water in the reservoir seems to be normal temperature, the radiator is not overly hot, and the AC keeps on blowing ice cold. Me thinks it is not really overheating, it just thinks it is. So where to start? Change the temp sensor first, or the thermostat? It seems the hoses are fairly firm, I don't believe they are collapsing from suction.
View 14 RepliesFord Super Duty (1999-2016) :: How Does ESOF Locking Hubs Work In Auto Mode
I took apart, cleaned and lubed my hubs. My question is: how does the vacuum make the gears work?
Does the vacuum force (suck) the nylon assembly to push the outer gear towards the center of the truck, sliding on the inner gear thus engaging the teeth so that the axle shaft turns the hub?
When the vacuum is gone, does spring pressure pushes the outer gear away from the center of the truck thus disengaging the teeth from the inner gear and allowing the hub to free wheel?
Is this vacuum source constant during 4wd and not present during 2wd or do I not understand how the system works? I have read about a “vacuum pulse” that locks the hubs and another pulse that unlocks the hubs and this confuses me.
BTW, I like the way the Auto lock works. I had a set of Warn Auto Lock hubs on my 78 CJ. They worked on the principle of a set of roller bearings that would lock (pinch) when there was torque coming from the drive shaft. There was no vacuum involved at all. The down side was that when you coasted, the front hubs would be in two wheel drive and so you would not get the engine braking on all 4 wheels. These ESOF seem to have solved this problem.
Oh, I should probably tell you that I just purchased my 04 F250 SuperDuty 4x4 with the 6.0 diesel, just had it a week. It has been 18 years since I owned a 4x4. Before this I owned an 87 F250 2wd with the 6.9 diesel.
Ford Super Duty (1999-2016) :: Transmission Not Shifting Into Tow Mode When Pulling To A Steep Hill
I have a 2006 f-250 super duty with a 6.0 and auto trans. I was pulling a trailer with about 5k of vehicle on the trailer.
Problem : after a long trip on good roads, I had to pull a steep hill. climbing the hill i did not shift into tow mode and all of a sudden my engine raced up to about 3k rpms and seemed to either shift to low or ( maybe ?) the Governor may engaged ?
Anyway I made it to the top of the grade and it seemed to be fine from there.
Question Is the trans broken, or did the computer maybe try to protect the trans ? It seems to work fine still?
Santa FE SM (2001-06) :: Transmission Started Going Into Limp Mode And Causing Check Engine Light To Come On
2002 Santa Fe, 2.7 AWD
The transmission has started going into limp mode and causing the check engine light to come on.
The codes given are p0750 and.... I think p0751, for shift solenoids C and D. There is also the generic Transmission Control Module code.
Limp mode only occurs at higher speeds although shifting feels a little rough at times in lower speeds.
If operated in manual mode the vehicle can be driven normally at all speeds without going into limp mode.
Fluid levels are fine.
With limp mode occurring in automatic but not occurring in manual mode, is it more reasonable to believe the solenoids are malfunctioning or the control module itself? I'm inclined to replace the solenoids but find it odd that the vehicle operates normally in manual. Also, can the solenoids be replaced without removing the transmission? It looks like I could get the pan off but am unsure if there is room to get the work done once it is removed.
Ford Super Duty (1999-2016) :: When To Use Tow / Haul Mode
This maybe a dumb question. But when do you use this feature? How many pounds should I start using the tow mode? I dont haul much. I just haul a 4place trailer with 4wheelers. And in the bed another 4 wheeler or camp gear. All the 4wheelers weigh over 650lbs wet and the trailer not too sure but its steel.
My truck doesnt have a hard time hauling, it shifts fine. Feels like its not even hauling anything. I did use to tow mode once but it seem it just keeps the rpm higher and I felt that the highter rpm was not needed when I was hauling.
Ford Super Duty (1999-2016) :: Any Way To Keep Tow Haul Mode On All The Time?
I have a 2009 F350 and use it almost exclusively for towing. Every time I stop to fill up or eat or whatever I have to push the tow haul button again when I start the truck- no big deal really just annoying at times because I don't always remember to turn it back on. Is there a way to have it turn on with the button and not turn off until I push it again (even after the trucks been turned off)? I suppose while we're on the subject same with the heated seats?
View 12 RepliesFord 6.0L Power Stroke Diesel :: F350 - Speedo Won't Work When The Truck Goes Into Limp Mode
What the problem is with my F-350 6.0. I have an intermittent problem with my Speedo reading zero while I'm doing 70mph on the fwy. since the speedo won't work the truck goes into limp mode, the turbo will not function at optimum level. I have replaced the diff. sensor, the trani sensor, the a.b.s.sensors, the instrument cluster to a reman cluster. Then when I had a local mechanic plug a laptop dianostic program on it as he was running through the system inadvertently the radio cut out, so I found that who ever installed the after market stereo they cut a few wires to the harness, I went to the junk yard found the harness end and replaced the end. so with all that said and done no one knows what is causing this speedo not to work and limp mode. about 4 years ago the oil pump stopped working and ruined the turbo so the whole front end of that glorious 6.0 was rebuilt the problem started about a year after that.

I have just bought a 2004 F-250 SuperDuty 6.0 Diesel with 98k miles from a Ford dealer (no warantee)...
Just after I drove it home I noticed the Tow/Haul mode switch was not working - no dashboard light and no transmission downshifting.
The dealer took the truck back in and kept it for 2 days, it came back working, they claimed to have replaced the gear shift lever. 500 miles later and the Tow Haul has failed again.
Ford Super Duty (1999-2016) :: Cannot Get F250 To Enter Program Mode
When I bought that '99 F-250 SuperDuty, it only came with one key and one keyfob. So, I had another key made (no chip in key, btw!) and ordered 2 more keyfobs.
I've followed the instructions to the letter. I cannot get the truck to go into 'program mode' to program the new keyfobs.
I've also ordered (and received) new door locks, ignition 'lock', since the key to start the truck doesn't work in the doors. Strange.
Anyway, the original owner said that he had to have the ignition 'lock' replaced and he lost the door keys.
What is the proper way to get this truck into 'program mode' so that I can program all 3 keyfobs?

Ford Super Duty (1999-2016) :: Heat Mode Switch - Compressor Does Not Come On In Some Conditions
I have a 2001 F-350 S/D w/7.3. Question is... Is it possible for the mode switch ( one controls floor/ defrost and A/c ) to not function or should I say leave the a/c on even if it is not in a/c position? What I have noticed was that when it is in the floor mode or the vent mode (not the floor/vent) the compressor does not come on. When it is in vent/floor or either a/c modes it does. Is this normal... I don't think so though I do know anytime the a/c is switched on compressor should come on but no time without a/c being on.. Maybe I'm wrong

2011 F350 loaded. Stuck on vent mode. Found actuator can feel it trying to move but something is stuck. Tried to remove the actuator but not enough room between the motor and a steel bracket welded in to the dash. (Not removable). Do I have to remove the dash ? (I suspect something fell inside and is stopping the big vent door from moving as i did pull the motor far enough away to move all the door except the vent door.
View 2 RepliesFord Ranger / B-Series :: Transmission Went Into Limp Mode With O/D Light Flashing
2001 Ranger 3.0 liter has developed a transmission casualty. I was driving along at 30 mph and the transmission went into "limp' mode with O/D light flashing and truck will only barely creep along with high engine rpm. When I got the truck home I was able to retrieve a p0720, output shaft speed sensor signal fault. I had hoped that replacing the sensor would solve this casualty.
Of course this was not the case. I have read all the posts I can find for this particular fault and realize that I must electrically trace the continuity of this circuit and also ensure that it's not grounded. I have been unable to find the needed wiring diagrams or pin out information.
Before I have to try and blindly start pawing through the connectors I'm looking for the pinout for the PCM and perhaps the bulk connector above the engine between the PCM and the transmission wiring harness. I am also keen to hear of any diagnostic tips that I may have overlooked.
Ford Transmission :: 1993 F250 E4od Limp Mode But No Codes
Alrighty now. I have a 93 f250 idi Na.
Before problems started: the truck.shifted all 4 gears fine.
Problem(s) begins: Then out of the blue(after I shut it off... even if it was for 30sec, and then turn it on ) it would go into limp mode but if I shut it off and then turn it on again, it would work fine. After about 3weeks/ 600 miles it just went straight to limp mode.
What I did: After 3-4 weeks of that, I replaced the solenoid pack(uncooked both batteries and waited 10 min before I hooked them up) with a eBay special. After that, I had 1st,....., limp 3rd, then it'd slam like check into OD. To get second(which was limp), I'd have to manually drop it in 2 and and let off the pedal before I'd put it in D, to avoid it slamming straight into OD. It would toy with limp and OD from 35mph-45mph. Then it.just went straight to limp mode again.
What I couldn't do because don't know how to solve: I went to go get the codes read and the connector was missing and only one wire was leading to where the connector should've been.
What I did...again: I replaced the control module in the firewall. Then my codes cleared up. And same problem as when I put the new solenoid pack in. But no codes.
What is it still doing????: it's a go round battle between complete limp mode, limp mode and wanting to go into gear(suited to proper mph&rpm), or 1st, limp2&3, and OD.
What I tried: TC lock-up switch.,. And it worked but didn't solve my problem so I scratched that one.
