Ford Super Duty (1999-2016) :: ABS Light Has Been Coming On Intermittently
Jun 15, 2013
ABS light has been coming on intermittently the last few days. Checked the resevoir for fluid level...topped up a bit. Changed the oil today and looked at the sensor connectors on the front brakes...ok... Got a new speed sensor and installed it....ABS is still on. Checked the old sensor with my meter and it is open circuit....no continuity, so I'm thinking it was the problem.. Is there something that has to be reset for the fault to clear, say with a code reader etc?

I have an 06 F350 with the 6.0 powerstroke. My battery light started coming on and will go out for a while, then come back on. Sometimes it flickers a little. I have checked/cleaned battery terminals (there was no corrosion). I have replaced the alternator. The batteries are just over a year old (10/12). I have not had any slow starting or any other symptoms other than the warning light. I am still having the same problems after replacing the alternator. I have checked with a voltage tester and it was reading 19+ when the light was off. When the warning light is on it was jumping from 12 - 15. This is an old tester so I'm not sure that it is working correctly. (not sure why I am getting the 19+). I'm going to go buy a new tester, but I was wondering if there is something else that could be causing the warning light. I know very little when it comes to electrical issues.

So I had a strange vibration coming from the drivers side wheel intermittently. Only when the hubs were in Auto , by locking them it would not happen. With hubs in Auto when it occurs switching into 4H made it stop immediately.
It would occur after small bumps and sound like driving over a rumble strip. I figured it sounds like a needle bearing in the hub going wonky and just replaced the entire sealed unit. So that should be it right? Nope.....
The vibration has changed tone and sound but still occurred after a slight bump to the right Driver Side tower. It now is a much deeper tone then before.
I made sure everything was reassembled correctly and tight. I notice however that if I remove the ESOF lockouts to rule them out it still occurs (no lockout in at all ) .
I can move the outer DS stub shaft quite a bit with one finger when the lockouts are not installed. Which would explain that why when the lockouts are installed and I lock the hubs it doesn't occur as the end of the stub shaft rides in the lockout.
I haven't changed the outer axle seals , but they really didn't look shot. It appears as if the play in the axle is coming from the pumpkin.
Side note: I took apart everything and cleaned it , there was mud, crud, dirt and water throughout the hum to and into the lockouts. see pix below for the mess and carnage. I cleaned and lubed everything up.

I have a 2003 f250 super duty with a v10
i was towing a trailer up and down lots of hills and the battery light on the dash came on. there was no effect on the performance right away. as i kept driving into town i was starting to worry if i would make it.
as i pulled into the carls jr parking lot, the ABS light came on, all the gauges shut off and the truck died just as i pulled into a parking spot.
i figured it was the alternator, had it tested at AutoZone (failed twice) so i swapped it out for a lifetime warranty AutoZone one (very small town, nothing other than an AutoZone)
the truck started after being jumped but the battery light was still on. i figured that the bad alternator killed the battery. the battery was 4 years old and they usually only last 3 years in the AZ heat so i bought a new duralast gold.
the battery light was STILL on after that. the Autozone guy ran his test--- engine off- battery tested fine starting---he said something was wrong with the starter (but it cranked awesomely!) running--alternator tested fine
i just can figure out why when i drive down the road i dash light will turn on and off at random times. the truck seems to run fine. I've even been under the hood shaking the wire while i had someone watching the dash and i cant seem to make the light go on or off

I have a 2006 Powerstroke F350. Recently, the "check air filter" light has been coming on. It comes on intermittently, and every time it comes on it makes a warning tone. Super annoying.
I reset the minder, and even tried unplugging it. No change. I think I must have a short in the sensor wiring, but I can't seem to find a wiring diagram that shows the air filter sensor.
Looking for a wiring diagram that shows how the minder is wired? Or What is the part number for the relevant wiring harness?

I have an '01 F350 super duty dually, 7.3L, auto trans. Over the past weeks my overdrive light on the gearshift would flash intermittently, maybe once every couple weeks. I chalked it up to a prior theft attempt where the steering column was damaged, and had turn signal/hazards issues after that.
Over the past few days my reverse gear has taken longer to engage, and is hard getting into the higher gears at speed. As of yesterday, reverse is out and won't shift out of second. Fluid level is good and clear. Could this be a PCM issue, or some sensor or relay?

I have a 6.0 and the air filter light keeps coming on and going off periodically, it seems like the engine is missing bad at times, runs better when tow/haul is on. I am not picking up and codes when I put it on the scanner. I'm possibly thinking injectors.. a friend of mine said something about checking out the "PCM"?

My 4x4 on my 2000 model f350 will not engage. The light works, comes on briefly on startup of the engine. When I flip the switch nothing happens. When I jumper the relays nothing happens. I do not have the factory hubs, they r warn hubs and the vacuum line to them is capped off. How to figure this out on why the 4x4 will not engage?

Need to know of an issue that causes the stability control light to come on for no apparent reason? I took it to Ford, they said no codes found and they replaced an ABS sensor, less than 5 miles after leaving, sitting in stop and go slow moving traffic it comes on again. I've been taking pictures to show them the randomness of this and they said they would look at it again.
Some mornings it comes on the when I leave and stays on and may be on after I get in after work (before I even move out of the parking spot), some days it's only in the morning and not on after work, some days it's on after work, some days it's not on at all but that has been rare that I don't see it at least once during the day, just seems odd and random so I suspect an issue.

2004 f350 w 125000 miles.
I had diagnostic done at Autozone and no problems from check or OBD. The battery light has been coming on for a few minutes then going off at random intervals. Today I was towing trailer and quads, around 3500 lbs, to go riding and it was on most of the time running on interstate and highways.
Seems like the serpentine belt doesn't have as much tension as I would expect. Is there an easy way to change the serpentine? That looks to be a real pita.

2001 f350 7.3 diesel and I come up with the codes for upper and lower dual generator fault. I have only one alternator not the dual.. I checked the gauge and it is running at 14 consistently. But the service engine soon light keeps coming on...I clear them and they come right back... Alternator is only 2 years old and not a rmf..

I have the infamous P0461 check engine light coming up. I filled it with Techron and even purchased Techron additive with a full tank and it's not going away. I've also replaced gas cap with OEM brand new yesterday and light keeps coming on after 2-10 miles.
Truck is stock. Bone stock. The fuel gauge is reading accurately and not fluctuating or jumping or behaving erratically. I checked all fuses and all fuses are good (under dash and on floor in cabin).

I have a 2007f550 auto trans with a flashing tow/haul light and a code of po791 coming up. Flashing light will clear in k/o position and remain off until placing selector in drive,after two feet or so of travel,an audible clunk and the trans acts like it is in third gear. Reverse is no change and highway will not shift into o.d. The iss "A" is listed as the culprit but ford doesn't list a iss a.

I have my 2004 f250 6.8L. Recently my truck has been having issue with the oil needle. When im stopped or coming to a stop my Check Gauge light comes on and my oil needle drops all the way down. As soon i step on gas it goes right back up. What could it be?

I have a 2012 f250 been in the shop 4 times for the traction control light just coming on randomly and staying on. they have flashed it changed something in the steering column forgot name of that and changed some sensors out. still does it. I think its a bad connection or bare wire is what I keep saying to them cause it only does it on rough roads and when its wet.

Am I the only one who thinks the tire pressure monitoring system is a silly feature? Is there any way to delete this and stop the light from coming up on the dash? I want to do new wheels and tires on my 2008 f250 and I don't want to deal with the tpms. Can it be tuned out from the computer?

ESOF not going into 4wd at all, except once in a blue moon... for a few times. All relays and fuses tested, swapped with known good units.
NO 4x4 light. so its electrical related. My hubs function like they should. when they are told to. I recently just swapped esof motor/gearbox on the TC. Worked 2x in the garage, went for a spin down the road, went into 2wd and stayed, wouldn't go back into 4hi brought it back inside, dinked around with resetting the GEM fuse. started working good. drove around and switched in and out of 4wd like 20 times no issues. next day, tried to go back into 4wd. nothing. Bring it back in the garage.
CURRENT DIAGNOSIS: Siting inside right now, If I flip the switch, I don't get anything. normally, that triggers the vacuum pump to suck hubs in. That doesn't turn on, the relays under the hood don't click. so it seems I am back up to the switch or GEM, or wires between.... Any test layout for how to test the switch in the dash? seems to be fairly simple, but I just wanted an exact view of what i need to test.
