I just bought a 99 f250 sd 5.4. The speedometer doesn't start working until it reaches about 30 mph. The transmission doesn't shift correctly until the speedometer starts working. I cleaned the speed sensor on the rear end but that didn't work. I don't see any sensors or switches on the tranny other than the neutral safety switch. What it is?
View 3 RepliesFor a 99 F250 7.3 with 6 speed manual..my odometer goes around but the speedometer does not work at any speed. A mechanic said he thinks the problem is in the gauge cluster but I would like to know where to start troubleshooting.
View 2 Repliesmy speedo doesn't work but, all the other gages do. I just replaced the front hubs, abs sensors, ball joints etc... I put a new sensor in the rear end this morning and still nothing isthere a fuse tied to this somewhere? am I missing something? it's a 5.4l with a 4r100
View 8 RepliesOccasionally while driving my 2005 F250 the speedometer will quit working & the abs light will come on. The transmission will also start to shift weird. If I pull over, shut the truck off & restart it everything is fine again. I can go weeks at a time before it happens again, but yesterday it happened twice. The transmission doesn't seem to shift real fast, but I think that is a separate issue. My first instinct is that the rear VSS is starting to go out, but I am not sure if these symptoms are common.

View 14 RepliesI have a 2000 F350 4x4 with 7.3L diesel and a manual transmission. While driving home yesterday my gauges (fuel, temp, volts, oil pres) stopped working. Within a couple min the speedometer and the tach also stopped working, but the truck was still running fine. Within a couple miles the engine stopped running, just like I had turned the engine off.
After having it towed home I checked all the fuses, none are blown, but there is no power to fuse #16 (15A, instrument cluster, high beam head lamp). Also in the fuse box under the hood, again, no fuses are blown, but fuse #9 (left head lamp low beam) and #11 (right head lamp low beam) have no power to them.

My speedometer quit working - stays on 0, my odometer stays on 271006.5 miles. Everything lights up, when I do a gauge sweep, the speedometer goes from 0 to full blast then back to zero. On the gauge sweep, my odometer states off all the code stuff like I think it's suppose to.
Anyway, I was lucky enough to get a speeding ticket - driving with the flow of traffic, with the police officer behind me for a mile or more. Pulls me over, explain my speedo just went out, he said he can't let me off but the judge might. So I'm trying to fix prior to a court date.
Here is what I have tried so far.
1. Replaced the VSS in the axle - no change to problem.
2. Replaced the sensors on top of the tranny (2 of them) - no change in problem.
3. Sent the cluster off to a repair shop - they said it worked when it left there shop - no change in problem.
4. Replaced the battery - thought it might have a dead cell. - no change in problem.
5. Unhooked the battery, turned on the headlights, waited 30 minutes, put it back together. (did this probably 5 times) - no change in the problem.
6. Replaced the diff fluid. - no change in problem.
7. Replaced the front left abs sensor on the hub - the existing wire looked like it had rubbed on metal - possible short? - no change in problem.
So far I've just been what seems to be time and money at it with no luck.
I have a 2001 F250, 5.4, 4X4. My ignition key stuck in the start position and when I pulled it back to the run position, everything seemed ok. As I started down the road, my speedometer stopped working and my overdrive light was flashing. Also my turn signals had stopped working and my A/C clutch didn't engage. Figured I burnt a fuse. I looked in both the under dash and power distribution box and all seemed well. I checked the fuse for the turn signals/flasher and it was fine. The flashers worked. Thought I might have fried something so I replaced the ignition lock and switch. Also my service engine light came on throwing a code for the vehicle speed sensor.
Looking for solutions on this forum and the internet, I learned that the turn signal switch could have gone bad and the VSS sensor is on the top of the rear dif and an easy fix. Well replaced the sensor but nothing changed. So I went back to the fuse box. Examined every fuse, big and small and I found a 10a with a small space. This was #24 under the dash. From the manual, "#24, 10A, A/C clutch, Blend Door Actuator, Trailer Tow Battery Charge Relay Coil, Four Wheel Anti-Lock Brake System (4WABS), Turn Signal." Replaced it and everything went back to normal. Turn signals work, A/C clutch works, no flashing overdrive light and speedometer works. All from a 10A fuse. If you have any of these symptoms examine all the fuses carefully. There's a 20A fuse for turn/hazard lamps and this other one buried that's only 10A.
On my '99 F250 PSD 4x4 the speedometer climbs very smoothly (normal) until I hit 54mph and then it just stops going up. Reviewing other posts I have changed the DSS (differential speed/ABS sensor) and the VSS (tranny speed sensor). Disconnected both batteries for several hours to see if it would clear.
Doesn't bounce, peg, go to 0, just won't go past 54mph. No power loss. Tach continues to climb and speed continues to increase. No strange symptoms except this 54mph thing. It is completely repeatable. All fuses under the dash and hood check out ok.
I've got a 99 F-250 7.3 with the 6 speed manual. My speedometer is accurate to within 1 mph or so. However when compared to a GPS unit, my odometer is off by about 50%...meaning it registers approximately 1 mile for every 2 traveled.
I was under the impression the mechanism that results in the speed being displayed is the same one driving the odometer and therefore if one was off, the other would be (conversely, if the speedo is accurate, so would be the ODO). How do I resolve this issue?
I bought a 1999 Superduty 7.3 6 speed and went out to drive it yesterday and noticed my speedometer stops working at 40mph. I saw many posts about this but no fixes. Bad cluster or vss? No abs light on dash. Still runs and shifts good. Only one yellow airbag light illuminated on dash...

View 1 RepliesI have searched everywhere, but I can't find the information I need for anything newer than 2007. I have the instrument cluster removed, and I can't figure out how to get to the bulb. In previous years, it just twisted out, but this one is different.
View 7 Replies1999 f-250 7.3 diesel. Speedometer doesn't work and neither does the odometer, the ABS light stays on and once you start driving the OD light starts flashing and the truck starts shifting weird. I've changed the rear ABS/VSS sensor on the diff and the OSS on top of the transmission at the tail end. Still no luck.....
View 5 RepliesBuddy has '96 Dump Truck. I think it is an F650 but there a no markings. It is small as dump trucks go, but has air brakes and an automatic transmission.
The speedometer goes back and forth full scale as if a speedometer cable were bad. Problem with that is, my buddy says it has an electronic speedometer.
About the only thing I can think of that would cause that problem is the Vehicle Speed Sensor.

While driving home from work I noticed the needle jump from around 55 to 70 on the display, then settle back in at 55 ish. First I just caught it out of the corner of my eye, but watched more closely, and it did it again as I drove. The tow/haul override button on the shifter was blinking also, (as if it was "Mad" about something)..
Then I noticed that the jump of the Speedometer needle was linked to when I changed from High to Low on the headlights, and vise-versaI was NOT in cruise mode The voltmeter did not EVER waver. (I thought that the increased current might be causing a temporary problem of sorts). Where to start looking?
Got a weird one today. Everything was fine all day. Got the old girl smogged this afternoon and made one more quick stop. Got back on the freeway and up to speed and looked down. Speedo said I was 90? Yeah right. I was going with the flow.
So I plugged in my bluetooth ALDL dongle and fired up OBD Link. Well, OBD Link showed normal and accurate speeds. As did a second app on my phone for giving speed. So my VSS must be working correctly.
So my speedo is showing about 25 over actual. When the ignition if off the needle sits between 20 and 25. so did my speedo take a dump? Is there anything else I might try to see if it auto-calibrates?
I have a 2002 F350 v10. I have 101,000 miles on it. When the Speedometer hit 15mph it starts to climb Rapidly to a 100mph then it stops and goes to 0. My miles go blank and when I slow down to around 5mph it comes back. I do know that I have a bad clock-spring and am changing that this weekend.
View 11 Replies just got 20" rims 295/65/20 Nittos. Is my odometer accurate and speedometer?
Not that it matters but its a 99 F350 CC LB 3.73 axle ratio
The 19.5" wheels are not an option on the 2013 F-450, unless you order a Chassis Cab. I'm certain many have made this change. My question is can the dealership make the necessary changes so the speedometer correctly measures the vehicle speed?
