Ford Super Duty (1999-2016) :: 2005 F250 - Alarm Went Off By Itself
Jul 15, 2017
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.

Just bought 2005 F350 XLT. Took it home last night and the alarm started going off at 2:30am for no reason. Stumbled looking for keys and it shut off by itself before I could(it sounded like it rearmed as well). At about 5:00am it went off again. We live in a rural area with not much around.
My understanding is that the XLT would be a Ford 'accessory' item. It does not seem to be too sensitive as I jumped on the back bumper to see if it would set it off but it did not.
The only thing I can think of is that last night, I had flicked all four of the Auxilary switched on the dash and forgot to switch them off. I popped the hood and none of those wires appear to be connected to anything.
I can't see why those switches would have anything to do with it but I am grasping at straws here.

My truck was sitting in front of the house, unlocked and the alarm disarmed. For no apparent reason, the alarm on the truck went off. I tried pressing both arm and disarm button on the FOB and the alarm would not shut off. I opened the door, started the engine and the alarm immediately turned itself off. I need to look in the manual and see if there is any condition that would cause that particular event. Strange to say the least.

I have a 2002 F250 7.3l with an aftermarket alarm. I can't read what the third letter is on the decal MV? 2000 Modular Vehicle Security. I added a pic of the alarm decal below. The key fob it had was aftermarket for the alarm and stopped working about a year ago. Today I unlocked the drivers door with the key and the lights started flashing and I can hear a clicking sound. It done this a few times back when the key fob still worked and I just kept hitting lock and unlock until it finally stopped. It won't let me start the truck at all and I have tried unhooking the batteries with no luck.

I have a new to me 05 F350 dually with 6.0. When I open the door with the key the alarm goes off and the truck won't start. How do I shut this off so I can get in the truck with the key. I can't just leave the door unlocked all the time. It has the key less entry, but I have not set new numbers yet, and if I give the keys to a valet, I don't want to give them the door code too.

Just picked up my F250 a few days ago and it's been great up until yesterday when I hopped in to start her up and nothing. It's a brand new battery and all lights worked, but the dash was dead. I attempted in vain for an hour or so to diagnose as to why this was happening and just happened to open the door with the key in the ignition and hit the door lock button....all of a sudden the truck starts beeping and the message on the dash said "to disable alarm start vehicle". I turned the key, the dash lighted up and away I went. What I may have done to cause this or has it happened to you? I'm thinking it's something with the key fob but not sure.

Truck is going on the market soon and would sell better if the 4x4 worked ...

F-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...

I 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 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

Dome light (and bed light) won't shut off. Been browsing the forums for similar problems but most of the time it is the door switch issue. I have my doubts about this since the 'Door Ajar' message in the instrument cluster is not brought up, unless a door is actually open. Similarly, when locking the truck and doing a door check, I get only one beep, means all doors are shut. 2005 Ford F-250 Lariat....

OK....my gas cap (5.4 gasser) wasn't put on properly at the gas station. A couple of blocks later, the "Check Gas Cap" notice came on. I stopped a few blocks later, and installed the cap properly. The notice STILL came on. After messing with the cap 4 more times, I gave up, but the notice is still on. Do I need to have it "erased" like a code, or is there a problem with the cap? Everything LOOKS fine...

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.

So, when trying to start my vehicle it doesn't even turn over. Just clicks continuously. Both of my batteries are putting out 12 Volts. I tried the old arcing my solenoid with a screw driver while key is in on position and I got a couple of turns, but it wouldn't completely turnover. My solenoid has power going to it. Checked all fuses that could coincide with this issue. Not sure where to go from here. I have an 05 Ford F-250 XLT.

2005 F-250, Diesel, 105K miles, all stock, fuel and oil filters changed in May, about 4000 miles ago.
three times in the last 4 days the truck has seemingly run out of fuel. Got a full tank about a week ago, at the same place I always go, so I doubt it is bad fuel. It ran thru a 1/4 tank with no problems.
4 days ago, it wouldn't start. It just didn't seem like it was getting fuel. It sat for several hours and then ran fine for about 15 minutes and then slowly died out. It wouldn't restart. It sat for 8 hours, and then started again, ran for about 15 minutes and I cut it off.
The next day, it started fine, I drove it 3 miles, cut it off, and an hour later it started but ran for only 10 -15 seconds and it slowly died out just like I was running out of fuel.
I started it this morning and it fired up right away. I let it idle in the driveway for 30 minutes, and it ran fine. I cut it off, went to start it 30 seconds later and it won't fire again.
The backyard mechanic I use for simple stuff wants to replace fuel filters and see what happens. BTW - twice when it wouldn't start, he hooked up his computer and it had no error codes. You can hear the fuel pump running when you turn the key on and the mechanic said he could feel the pump working when he put his hand on it.
Should I let him do that or is there something else we should be looking at?

My 2005 F250 started stuttering, lurching, having wild swings in rpms, nearly dying at stop signs, no pickup when stepping on the gas, then taking off like a bat outta hell. After reading many, many posts here and on other sites, I have concluded that the most likely culprit is the ICP sensor, so I picked one up today (along with a EBP sensor - another story). It appears from the many posts that I have read that Ford/Navistar have frequently changed the location of these sensors. My question is: Where are the ICP and EBP sensors located on the 2005s (actual manufacture date is 07/2004)?

I have a 05 f250 diesel 6.0 with 173k. Between 35-60 mph it has started a humming sound and when the throttle is released the sound stops. I still have power boost etc. Someone mentioned degas cap, turbo pedestal or turbo pipes cracked.

05 F250 4x4 6.0... Lately, I have noticed a little stiffness in my steering. Mainly when I turn left - it just feels like the truck doesn't want to come back to center like it should...almost like a tire is low on air (they're not - I checked) or a tire has laid over.
I have checked power steering fluid and looked at all bushings underneath. Any chance that the steering stabilizer could be causing this issue? Also...do these trucks not have any grease fittings in the front end? I have looked twice and still haven't found any (in my defense, I haven't had the truck very long)...
