This morning my 02 decided to turn the ABS light on, and start bouncing the speedometer. plus, the OD light is flashing when stopped with foot on the brakes, but the trans is shifting fine. Nothing changed on the truck except almost 3 inches of rain fell last night. Will AE tell me if the VSS is going bad?
View 14 Replies2002 e350 7.3 diesel transmission... At 7 miles the speedo began bouncing and truck drops into second. Parked it 30 minutes, stated up no problem until 8 miles and the it started again. Have checked most of the electrical, changed speed sensor and transmission position sensor. Only error code 2-3 rd gear mismatch.
View 11 RepliesA few weeks ago i lost the speedometer and the abs light came on. 6 hours later when i got home I tried diagnosing it, but everything worked. Yesterday, the same thing. No speedo or odometer, abs light is on, and the OD off light is flashing. But the trans still works fine, going through all 5 gears and torque converter lockup. plus, pushing tho OD button turn OD off, hit it again and OD engages again. (the truck has a 5 speed allison trans in it) i put the scanner on it and got No response from module for the ABS module, the GEM/central timer, and Hybrid electronic cluster. There are no trouble codes, but it did show P0500 vehicle speed sensor A this afternoon on the way home, the speedometer and odometer came on and worked for .4 miles, then went out again. Where I should start?

I drove the truck to work. It was fine. I start it up at quitting time and let it idle for a minute. When I pulled out of the parking lot and the od light started blinking. After about 8 miles I stopped at a red light. When the light turn green and I drove off the speedometer is working again. The od light flashed for another mile or 2 then stopped.
View 3 RepliesSpeedometer not working and O/D light blinks, I have a 450 and a 250, 99 and 2000. On 450 this is an intermiting problem. Stop truck turn ignition off, restart and it all works now. Just started on my 250 and stopping and turning ignition off cures the problems for a few seconds, after i get moving the speedometer doesnt work and then light starts blinking again O/D light. Where do I need to start?
View 7 RepliesMy ICP is running low, 460 to 480 at idle and bouncing all over the place. It doesn't get above 2500 or so at WOT acceleration the ECM is throwing a "pending" DTC for low ICP. I removed the ICP regulator solenoid coil and cleaned the inside, filled the connector with dielectric grease and reconnected. That worked for a while but it's creeping down again. I'm going to pull the ICP regulator and clean and rebuild it as soon as I figure out how to do it w/o taking the whole HPOP assy off. How to determine if the root cause is the ICP reg. or the HPOP? Regulator duty cycle is running 15-20% at idle and less than 30% the rest of the time which makes me think it's the HPOP.
View 14 RepliesI have been "fighting" a front tire cupping problem on my L99 F350 Dually 2wd since I have owned it.
I got LOTS of paperwork with it, one of which was a service ticket from the dealer where it was bought new (with VERY low miles on it) saying several passing motorists had informed them that the front tires were bouncing down the road.
I have read this service complaint several times and I now feel that has something to do with it. I bought the truck with 70k on it some 8 years ago-the PO had installed EXPENSIVE Michelin XPS Rib steering tires on it and they were already destroyed by cupping.
I replaced all 4 shocks, and all 6 tires, begged the folks to FIND something wrong/loose/worn out on the front suspension/steering and they found nothing, they aligned it. THAT set of Cooper Discoverer HT tires did exactly the same thing, except I spent a lot of $$ having the tires rotated.
Now I have a set of Firestone TransForce tires on it and its been to a HD truck shop where I begged them to rip into the front end and FIND something wrong-THEY DIDN'T. THEY installed camber bolts and aligned it, yep, you guessed it STILL CUPPING!!
So, now I'm thinking is it possible that the wrong coil springs were installed at the factory causing this bouncing that the original owner reported to the dealer? I have now destroyed 2 more tires and getting tired of it.
I have a 2002 f250 CC 4wd 7.3 and I have no power to my reverse light sockets. I am stumped, all my fuses are good, I don't think there's a relay so i haven't checked that. My neutral safety switch is good, I'm getting power to both the blue/pink and black/pink wire. What it could be, at first it was constantly blowing fuse 27 every time I put it in reverse but then it stopped blowing it obviously because they won't come on.
View 8 RepliesLast night the speedometer started acting up, would fluctuate when the truck went over bumps and completely cut out on moderate right turns. Looked underneath as well as one can in the dark and couldn't find anything loose.
This morning I searched on here and the VSS came up numerous times as a common failure. $15 and about a half hour later I had it installed, and while I was under there I took a better look at the other connectors to double check harness connections for tightness and cleanliness. It all looked good, so I went ignition on... and the light came back. Tried clearing it by keeping the diag connector unplugged while switching ignition off, but no go. Took it for a quick spin around the parking lot, and the speedo was completely dead.
Hit up my factory ETM, found all the relevant connectors and set up a wiggle test of the VSS circuit with the DVOM on audible continuity check. Found one of the wires had chafed against the body right by the under-cab harness connector and worn almost completely through. Cut out the bad bit, soldered and heat-shrunk a patch in, and took it for a spin. Voila! No more ABS light and a working speedometer.
Also fixed the fuel gauge sending unit wire which was in the same connector grouping and chafed (but not yet broken) in a similar manner.
Using the hypertech speedometer calibration tool on trucks?
I'm running 37s and need to calibrate it. But I don't want to buy a performance chip with the calibration tool?
I have a 2002 7.3 4x4 truck. The 4x4 will not engage, the lights on the dash don't even light up. I took it to the ford dealer and they said the fuse box and gem module. (800.00 to fix). They said the windshield leaked and shorted then out, so I needed to be replaced? I have replaced the windshield and fixed the leak, my question is the fuse box and gem a plug and play and do different years work?
View 5 Repliesso got to work today, truck engine light comes on all foward motion stops. Just coasts and idles along. I have 280k on the orig stock trans. I also have dp tuner and did the valve body upgrade along with adding the 6.0 cooler hoping to extend the life of the trans. Reverse works. So i asume I am needinf a new trans. My options are Ford HDr4100 orig 4100, Or BTS built trans. I also pull a toy hauler as well. My question is If I order the BTS can I have a my local shop install it or does it need to be programmed at the dealer. If I get the HD from ford installed will I have to remove the dp tuner chip to get it programmed and also will i need another new valve body replacement.
View 14 RepliesI have a 02 f250 4x4 7.3l.... I drove it all weekend and no problems. It sat till yesterday I got in it to go to church. It started up and had a little miss was around 60 f. Then the od light started flashing. Not in any code just constant flash. I was parked down in my drive way. It idled fine but acted like it wouldn't take fuel. So looked around and found the hose on the map sensor was broke.
So today I fixed the hose. Checked the oil level and battery connections. Still running weird and flashing od light. I got under the hood and wiggled plugs I unplugged the ice. It revved up then back down and started running smoothly. Got in it and it backed out of the drive way. It ran and drove fine. What I need to know is why??? The ice is a new one from Ford.
Door ajar light stays on. Lights were staying on until they timed off but after two days they have returned to normal operation. Where the switch is located on the door frame, I can't seem to find it. 2002 ex psd.
View 12 RepliesBit of a confusing one as of late. Doesn't happen every time I drive, maybe 50% of the time. When I start the truck up, torque pro reads voltage at 13.9-14.1 consistent. After 30 minutes it usually drops to around 13.7/13.8. Sometimes, battery light comes on, voltage doesn't drop. I can drive the truck, park it, turn it off, restart, no side effects.
I notice if I stop, turn off the truck, and restart it, torq pro will begin to read a voltage of 12.8.13.0. Sometimes it won't budge for an hour, sometimes it climbs right back up to 13.8, sometimes the battery light goes off, sometimes it stays on.
Alternator was replaced a month ago, both batteries replaced a week ago, all terminals cleaned and secured at the time of replacement. Truck behaves perfectly normal, I'm almost at the point of putting a piece of tape over the light and ignoring it, but was curious before I go that route.
My speedometer was intermittent for a while, stalling, then moving, but never above the actual speed. Now I turn it on, but as soon as I move, it travels up to 38mph then stays there until I turn off the engine, then it hangs for 4/5 seconds, then drops to zero.
I replaced the VSS in the rear diff, and the one on the tranny. I checked all fuses. There are no other dummy lights or indications. Bad ground? I'm hoping I don't need a new gauge cluster.
Just bought a 2002 F-250 4x4 Off-Road Crew Cab 7.3L and the airbag light is staying on. I have found out after the fact that the truck has been previously involved in a front end collision. The damage was to the passenger side front. I turn the ignition on, the airbag light will come on solid (just like all the rest, with the exception of the 4x4 and 4x4 low) then go out. Then it flashes slowly 2x then 5x, then goes out for a bit then repeats a few times before staying on. This tells me I am getting a code of 25. I have searched with no luck to narrow this issue down. Everything mechanically works, cruise, horn, etc. The only thing I can find wrong is when I engage the 4-wheel drive (floor shifter) the indicator lights do not illuminate in the instrument cluster. Neither the 4x4 nor the 4x4 low. I am unfamiliar with this truck, so I don't know where to began searching. I cant afford to take it to a dealer and I have children in the truck quite often, so I would like to remedy this very quickly.
View 9 RepliesI have a 2002 f250 screw. my door ajar light is lit up on the dash. I have tried the wd40 trick, pulled the sensors and bench tested them. What are the codes the instrument cluster test has for each door?
What I am thinking is, if we get a list posted it would be much easier to diagnose the door sensors for others. there should be a open/closed bit for each door. possibly a code for all doors open too. I am curious if there is a code for bad communication on the VSM.
From what I have read, correctly working the doors should read 00 when they are closed. drivers front open=80, pass front open=40 ... My door code does not change no matter what combination of door open/close I use.
Truck is 2002 f250 crew cab ...
My code is C0 ...
I just brought a 1996 Explorer 4x4 V6 XLT from a friend thinking it was an easy fix by answers I found of the problem on the net. Even search threw the threads here. Right now my OD light is flashing and the speedometer is bouncing around not detecting the current speed. Also it's not going into gears smoothly. I've replaced the VSS as well as the gear on the end of it. What was the fix for it?
View 4 RepliesVehicle: '99 E350, V10
Symptoms: speedometer bouncing, O/D flashing, harsh shifts. Symptoms do not present until the van has been driven at highway speeds for about 20 miles. Then, the speedometer starts to bounce a little. Then, after another 5 - 10 miles, the O/D light starts to flash. Then, with a few more miles, the harsh shifting begins.
Parts replaced: neutral safety switch, rear ABS/speed sensor (twice), instrument cluster.
Each time after I replaced a part, when I drove the van, all was fine until it had been driven at highway speeds for about 20 - 25 miles, regardless of whether the engine was warm or cold. Where to go next with it?
