Ford Super Duty (1999-2016) :: P1747 Code - EPC Solenoid Short Circuit
Feb 16, 2011
I have a f350 2000 4x4 automatic 170.000 miles. Service light on and OD light flashing. I have code p1747 "EPC solenoid short circuit"
This code make that the engine runs slow without power and hard shifting. I change all the solenoid body and check all wiring.
Later using a voltmeter i separate EPC solenoid wiring and see that have 5 volt. If I don't accelerate more 2000rpm OD light is not flashing and truck works normal but slow.
When I accelerate more than 2000rpm OD light begin to flash and transmission fail more. I check that EPC wires mark about 0 volts when OD light is flashing. Transmission hydraulic system seems to be ok because oil is very red and clean. Maybe another sensor is making this failure....

I have a 4r100 in my 2000 f250 7.3. I am getting a P1746-EPC Solenoid, open circuit. Does this mean this particular solenoid in the solenoid body has failed and should i replace the solenoid body?

It's a 1999 f250sd 5.4l auto. Has code p1747. Truck shudders and almost dies when you drop it in gear, put it back in park idles fine. I have read all the post on here about this and checked wires from trans up to pcm look and test well. Tested plug c1048 wires with the digital meter to body ground with battery unhooked and got 6.66k ohms on pin 11 circuit 925, 421 ohms pins 1 and 12. Plugged c1048 back to trans checked 925 w/y wire at plug c103 got 9.1 ohms back to trans. Is the EPC solenoid bad or is it pcm? I think its epc but want to verify before i take trans apart.

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?"

CEL turned on this morning heading to work. Truck drove completely normal with no signs of altered performance.
Stopped by Autozone after work and they checked it with a code reader.
Came back with P0442 - "Purge Valve Solenoid"
Part sold with or without bracket.
Is this a common part to fail? How can I be sure it has truly failed? Is it acceptable to reset CEL and see if it fails again? If so, how do I reset? Where is part located?

I have a 2006 F-350. I got a code p2623 ipr circuit open. I ordered a new one and currently waiting on it. I pulled the old one and the screen has been replaced already. How often do these valves go bad? Is there anything else I should check?

Have an intermittent miss I can feel when driving 2006 F250 5.4 l 4x4 stick; Freeze frame from Cen-Tech 60794 (from Harbor Freight) scanner follows.
DTC CNT 0
DTC FRZF P 0352
FUEL SYS1 OL - FAULT?
FUEL SYS2 --
LOAD PCT 25.9
ELT (DEGREES F) 186
SHRTFT 1 0.0
[Code] ....
I can operate the scanner but what these ranges should be. What might be causing the miss? This scan shows 951 rpm, I was idling along in 1st in traffic, but I have also felt the miss at 75-80 mph (about 2300 rpm) on the Interstate and at other times, with light loads in the 1500- 2000 range in town.

My scanner reads P0001 Fuel Volume Regulator Control Circuit Open. My truck shuts down without warning, runs great otherwise. I've changed 2 grey CPS units and now have the Black IH one installed. What the Fuel Volume Reg.is? Is it the IPR on the HPOP?F250SD 7.3 225,000 miles.

I recently picked up a 2005 f250 SD 5.4 4x4... I was having issues with sporadic shifting and wandering shifts while cruising around 100kph, scanned it and came up with p0721 OSS sensor circuit performance fault.
I checked the harness and all looks fine, now I attempted to remove the OSS at the rear of the tranny, got the 8mm bolt out however could not, for the life of me get the sensor out. I tried not to use pliers to twist the sensor or anything for fear of breaking the sensor off and having bits go into the transmission.

I have a 2006 f-350 6.0 and i went to fill up my truck with diesel. After that the truck did not start. Currently has the code p2285 - injector control pressure sensor circuit low. I tried disconnecting sensor, still no start.
I have the torque pro app and another 6.0 that I use for comparison. Check power at ficm 48 volt, flp 11.5v, FVP 11.5v. Hpop while cranking shows 1400 psi. removed oil filter and see low pressure oil ok, fills up reservoir. ipr at crank about 65%. fuel filter full of fuel.
Replaced the dummy plug on passenger side because originally hpop was very low psi 12. after replacement it went up to 1400 on cranking. What should I be looking at next, should I be removing ipr? should i be looking at crank sensor or cam sensor? Just installed 2 new batteries also because my dad kept cranking the truck until it died.
Checked to make sure fuel cut off relay not triggered, Ok. The truck has been having long cranks before it died. Also right now the injector cycling is 10 seconds long while on my other 6.0 it is about 4.

I have a 1999 Ford Explorer with the V-6 SOHC that is stuttering and stalling when I try to accelerate. A very slight acceleration will get the vehicle moving, but anything coming close to normal gas pedal pressure causes immediate stuttering and/or stalling. Check Engine light came on when problem started yesterday.
Where is the EVAP System Canister Vent Solenoid? I bought a code reader after beating my head against the truck all afternoon and got code "P1451 EVAP System Canister Vent Solenoid Circuit Malfunction". My Haynes book says on the left side frame rail... can't find anything along there that looks like it (based on picture from Rock Auto for replacement part) and found some people online talking about it being in the engine compartment on the passenger side...
Just crawled all over the truck and I think I found the charcoal canister, but couldn't trace it back to the vent solenoid... There was something right next to the canister, but again, it looked nothing like the replacement part listed on Rock Auto...

My starter solenoid keeps dying. I can't use a retail chain part. They burn up in a day. Always Motorcraft and it only lasts a year or so.
Any way to test this thing to see why it burns out prematurely?

I had a bad starter solenoid on the fender in my truck I swapped it out and then my starter went so I swapped it now it is not disengaging the starter If I turn the key to the run position it starts cranking and fires right up before I an let the glow plugs cycle or anything and it won't disengage the starter I turn off the truck and the starter is spinning loud for a couple seconds till it stops no matter if it just start the truck or start it and run it for a couple minutes then shut it off. 99 7.3L ....

Last week the ABS light comes on and will go off after a short drive. Obviously the Scanguage II does not read the code. I have replaced both front hubs last year and have less than 6k miles on them. I have checked the connections, and are good. I changed diff fluids around the same time as the hubs.

My 2001 F250 will not start (clicks). I verified its not the battery and even tried to jump start it. I have never replaced a starter- but before I do that I read where there is another solenoid under the hood somewhere. I always thought there was just the one on the starter itself.
Two questions:
1. where is that other solenoid located and should I replace that first?
2. How difficult is it to replace the starter? I am pretty handy.
The issue is that I cannot get it towed easily - I just need to get it started at least once since my plow is still installed and it's hooked up to a trailer..

99 F250 Super Duty 5.4 has a p7147 error. Traced all wiring cant find any short. Bought reman solenoid pack # are f81p-7g391-cb with green cover my old one in trans is f81p-7g391-ba with blue cover. Are these interchangeable? Have tried to read up on pwm & nonpwm and getting confused.

I have a 2010 f 250 super-duty and i cannot get vacuum past the solenoid mounted on top of the radiator. Ford has given me nothing but bad advice. I know i have a vacuum leak after the solenoid and need to replace the lines going to the two hubs but when i switch on the 4wd and hook up a vacuum gauge the vacuum is good up to the solenoid about 12 inches. i constantly have 12 volts going to the center lead but nothing else in the other two leads either in 4 high, 4 low, or 2wd. Am I missing something here? shouldn't there be a voltage change when i turn the switch to 4wd to actuate the vacuum solenoid to let the vacuum pass thru the solenoid? I have tried replacing the solenoid but that did not work. Also use rubber vacuum line and make at down to the hubs?

I have a 2006 F250 Super Duty w/ turbo Diesel. Took to dealership for "hopping" feeling when turning sharp. Was told that 4 wheel drive solenoid was bad. Where this solenoid is located? I know I can fix but want to know where it is located.
