05 5.4 F250 4x4. Keep getting those codes. Can't find any vacuum leaks. swapped rear O2 sensors. Fuel filter twice in last 11k miles last time was 1k ago. Will the 430 code cause the lean codes from a bad cat? I've been getting the 430 code for at least 4 mo's.
View 6 RepliesMy 2005 f250 5.4 with codes p0171 and p0174. I have replaced fuel filter, MAF, Checked for vac leaks by smoke and water test.
I don't have a way to check fuel pressure on this thing since it must have been to much trouble to put that test port on the fuel rail!!!
What would be causing my left and right bank lean codes? Truck still seems to run fine. I have also been getting number 6 misfire. all within the past week. I know Its due for a tune up but would a simple tune up fix these codes. Also besides plugs and primary fluids what else should I be changing. I don't want to be getting to involved just the main stuff.
View 5 RepliesI just got my 2005 F250 diesel out of the shop. The errors codes P0299 and P2263 were listed on the computer. The service done, was to clean carbon from turobo charger and service the EGR valve. I talked with the mechanic and he recommended that I use Cetane Booster Additive. What would the Cetane Booster do? How would it prevent the carbon build-up in the turbocharger? What should I do to prevent turbocharger carbon build-up?
View 3 RepliesMy '05 F250 (5.4) started misfiring and threw codes for p0300, p0305, p0307, p0308,and p2198. I used an inline spark checker to check cops, which all had spark. Replaced 5, 6, 7, and 8 plugs and cleared codes. Ran truck for a few minutes and codes came back. Switched #5 and #6 cops and cleared codes. 5,7,and 8 cylinders still misfiring (same codes). Truck only has 36,000 miles and spent alot of time just sitting. Plugs were original plugs.
Replaced 5-8 with Autolite OEM replacements. I haven't checked cops for resistance yet. Weather was pretty cold when problem started. Threw in about 10oz. of Lucas to no avail. I had this problem last winter with the same cylinders throwing codes. Threw some Lucas in the tank and idled truck for approx. 1/2 hour and problem went away except for stumbling most every time truck came to a stop. I'm starting to wonder if it's a coil or a fuel issue.
After finding that a battery was low and not getting charge, they found the alternator was bad. Replaced that. Next the battery that was low was able to be charged and did not effect the other battery. Both batteries have been load and charge tested and they both read 84% charged. I am told this is "good."
Next I swapped both fuel filters and did the oil change as well. I finally got a chance to get my friend to run his scanner on it. The results are injectors and FICM. The codes are PO261, 264, 267, 270, 273, 276, 279, 282, and finally 611. I guess this means that the FICM is toast.
I have tried salvage and no one has anything. I guess I still don't understand how this truck is capable of running daily with the computer throwing every code dealing with the injectors and the computer that runs them.
Getting these lean codes P1131, P1151, P0171, P0174. I was getting a knock sensor code before but not now. It will not idle it just dies and runs rough till I get at higher rpms gotta feather the brake and gas to go anywhere.
View 5 Replies2005 F250 6.0L ... My truck is running really rough when the engine isn't all the way quite warmed up. once the truck is fully warmed up to normal running temp it runs good. I am getting four engine codes. P0672, P0673, P0674, P0676 These codes say 2,3,4, and 6 glow plugs have a open circuit. Can this be the cause of my problem?
View 7 RepliesWhere to start. Have had to replace a few COP's in the past and replaced all spark plugs 20k ago. Truck runs rough at idle and sometimes stalls when changing gear. Strong exhaust smell when sitting idle. If I put my foot in it there is hesitation. Engine seems to smooth out quite a bit but also seems like it's getting more power in stages. Codes P0426 and P0345 ....
View 2 RepliesOk so my F250 died last night. I read the Pcodes and came up with P2198 and P0506. I am pretty good with fixing the truck but need to know exactly what is wrong.
View 5 RepliesThe engine was just rebuilt, 7.3L diesel. New bottom end, cam and turbo also new harness for valve covers and injectors, new #8 injector(#8 cylinder lost compression). The engine cranks and idles great. Run it up to 1800rpm - 2200rpm and you get a miss or skip. Almost like the engine turns off and back on very quick, and it makes a clank noise. No codes, reading it with a OTC Genisys 4.0. I also swapped the PCM and IDM with another truck and it still does same thing. Other truck runs fine. Year model 2000 w/ 230,000 miles
View 1 RepliesLong time follower, first time user. 99 F250 V10 180,000 miles: About a month ago I replaced both upstream oxygen sensors. I know have the following codes:
0135 and 0155 for Upstream Heated Oxygen Sensor Heater HTR 21 and 11
Circuit Malfunction Bank 1 and 2
1409 for Exhaust Gas Recirculation Vacuum Regulator Solenoid Circuit
I checked fuses and PCM relay and all are good. I have 12 volts to both oxygen sensors and no noticeable wire burns. One of the possible causes given on code printout for 0135/0155 is to check for a disconnected hose to the EGR. All hoses are good. One of the possible reported fixes for EGR code 1409 is to repair oxygen sensor wiring. So my question is: Are these codes related. If I replace the EGR vacuum regulator solenoid, will this clear my codes from the oxygen sensors?
I have an intermittent problem with my 09 F250 Diesel. A few times now under hard acceleration I have had the trans seemingly get stuck in 3rd gear. The little service required wrench symbol showed up on info screen but after shutting off the engine no codes were present. A week or 2 later this happened again and I ran diagnostics through my Spartan tuner and got P0771 and P2704 for codes.
Again they cleared when I shut the engine off. Since this is an intermittent problem, only after hard acceleration, would it make sense to change tranny fluid, maybe do a tranny flush? Or am I off to the dealership for a rebuild?

I have a 2008 f250 superduty with the v10. Just today I was driving and engine picked up.slight miss it's rainy. I thought coil pack, but it left me on side of road. Got fired limped home won't go more than 40mph. Runs rough, no power, checked codes and get P0340, p0357, p1336, and P2195.. Where to start.. My daily driver and have to get back on road.
View 1 Replies2 weeks ago I had the check engine light come up on my 2011 F-250 6.2 XLT. Did a diagnostic check and Codes P2098 and P2272 came up. Did some research and found out the second O2 sensor on passenger side had gone bad. I replaced it with a Motorcraft O2 sensor and cleared the code. It has not came back since. But still not getting the fuel mileage I got before. What else could be wrong?
View 5 Replies2005 F-250 King Ranch Diesel ... My truck when I got it the 4x4 wouldn't engage. I replace the front inner seals, and the lock outs. Still wouldn't work. Took the shift motor off and freed it up and it worked fin till today. Changed the shift motor and still nothing. This truck has been nothing but problems since I have had it and now this ... Truck is going on the market soon and would sell better if the 4x4 worked ...
View 13 RepliesF-250 2005 XLT 5.4L 4X4. Had ford for a few years now (Escape as a personal vehicle and econoline as business vehicle). Now I'm having a little problem with 4x4. It wont engage. Worked fine last week and now nothing! I did check all the fuses and when i switch to either 4Lo or 4Hi I can hear a clicking sound behind the switch but feel like it's getting blocked or something. Tries a few time then stop...
View 14 RepliesI have had the ABS light on for about a year now. I looked thru the forums and found that the typical reason if a faulty rear VSS (vehicle speed sensor). I found a replacement part online and got it ordered and replaced the original part. Simple 5 minute fix, but it didn't fix it!
Now when I get in and start the truck the ABS light is off, but after I drive off about 20 yards the light comes back on and stays on.
The other day someone stepped out in front of me at a cross walk and I hit the brakes pretty hard and although the truck stopped in time, the rear wheels locked up, so I'm thinking the issue is at the rear.
I came home from a week's vacation and towed my 16' toyhauler to and from the Sequoia Nat'l Park ... no issues during the entire trip. Guestimating about 5 hours after being home, everything was unpacked and the truck/trailer locked but still hitched ... suddenly the alarm went off ... all by itself! Using the ignition key, I was able to start/stop the 6.0l diesel motor, but the alarm kept going.
I pressed the lock/unlock buttons but still the alarm was going off! I repeated this a few times and concluded that only recourse was to disconnect the batteries. That stopped the alarm. While doing the disconnecting, I detected a faint electrical hot, maybe a burn kind of smell but no smoke of any kind.
I'm worrisome about reconnecting the batteries to see if the truck is back to normal ... I will probably just have it towed to a mechanic ... in any event it's going to go somewhere to be looked at this coming Monday.
I've had DTC P0171 & P0174 (lean in bank 1 and lean in bank 2) for a few weeks now (check engine light cued me on it). Autozone scanned it for me. It's on a 2003 F250 SD 4x4 5.4L.
My first step was to clean the MAFS. Light came back on in about 30-40 miles. I then replaced the MAFS. 30-40 miles and the light came back on.
My first thought was disconnecting the battery wasn't resetting the comp and thats why the light was comming back on.
I went and picked up an Actron cheapy OBD II Scanner today at lunch. Cleared the codes with the scanner and drove back to work.
Checked the codes when I got back (no light on but was curious) and it shows P0171 & P0174 pending.
I've checked and the dipstick is seated properly. The hoses on the air intake appear to seated properly as well. The top hose is a pretty loose fit but it was seated all the way down. The top hose was oily. Not sure if this is normal or not. Could the loose fitting oily hose be the culprit?
Also, what is the lower hose? It comes off the back of the air intake and goes to the driver side valve cover. I know it's not the PCV hose as that is on the passenger side valve cover....right?
I have an 05 F-250 with the 5.4 liter motor, 4" lift, 35" tires 4x4. I have not had any problems with the truck and have 110,000 miles on it. the only thing I even did to it was replace an alternator. Recently it seems to have lost power.
I use the truck mainly for hauling my smaller horse trailer which is roughly 7500 fully loaded but most times i haul it at about 5500lbs.
I also have a 2003 7.3 which we pull at 20,000lbs no problem
