Ford Ranger / B-Series :: Speedometer Dial Started Climbing When Driving On Highway - Erratic Readings
Dec 16, 2013
On my '91 last week I was driving on the highway about 60-65 when all of a sudden the speedo dial started climbing to 70-75-80-85 and past. The odometer seems to be working ok? Still when I drive it still operates in the same manner. It never bounces around or falls back. The needle is sort of stable such if I maintain a speed the speedo will maintain even though it's incorrect. There is a slight wavering of the needle meaning it's not as stable as it use to be. With the odometer working I was wondering and don't know. Does the cable drive the needle or is it electrically controlled? I'm thinking of grabbing another instrument cluster it that is the problem, I'd like to know more about it and understand how it works so I don't just throw parts at it until it's fixed.

I've been driving my 99 ranger 2.5 now for 2 weeks now. Overall I am very impressed and happy with it. Everything seems to be near perfect and in top shape on this truck and I feel like it'll have no problem paying me back.
I've recently noticed, however, that whenever I start up a hill with the climate control on, it shifts from whatever I set it to, to the defrost vents. It returns to the vents I set it to after I crest the hill, and doesn't change vents if I don't drive over hills. I live in a hilly area so that's not convenient. And with summer around the corner, I want this solved.

My speedometer is erratic, not reading correctly, and the trans is not shifting right. It gets up to 3000 RPM and I have to back off the throttle to make it shift to 2nd. Then after driving a while everything starts working right. Next time I drive the truck it does the same thing.

I was driving up a hill an it started to loose power. i got up to the top of the highway an stopped an it just shut down. got towed home i thought it could of been the alternator but dose not seem to be. took the belt off to spin the motor an its not spinning. drained the oil an there is no metal in it to see if the motor was done. i try to start it an it just dose a click click an that's it. Is the motor done or is it a transmission problem?

I have a 2003 Ford Ranger, recently I had the heater core fail. One thing that happened during the heater core starting to leak is the "THEFT" light came on brighter than normal and no longer flashes when the truck is off. Also when the theft light started acting up the O/D OFF light came on and would not shut off. If I pushed the O/D off button the Theft light will go out and then come back on after the button is released.
After the heater core was replaced the lights stayed on as described above. Every once in a while the O/D off light would stay off but then come on later. No really problem besides the lights and O/D off button not working. Now today the O/D off light started flashing and the truck kept shifting in and out of O/D.
I'm leaning towards a speed sensor issue. I'm going to check and see if there is any codes tonight and will post my results. One other thing that happen with the heater core leaking is the "CHECK ENGINE" light came on because the O2 sensor was shorted out. Have the O2 sensor now and plan on replacing it while I trouble shoot the erratic shifting in and out of O/D.

I have a 92 ranger 6cyl 4L. The truck stopped running while driving then kicked on again, it did this several times over about 20 minutes then finally died and now I can't get it started. I recently replaced the fuel pump and filter and spark plugs and wires. I get spark if I ground the plug and some gas will pour out of the fuel pressure test valve when I stick a screws driver in. When I check engine codes I get an all pass. Truck will turn over and sometimes run for 2 or 3 seconds but that is it.

Its a 1994 with 4.0, automatic, 4x4. Running fine, parked it, a week later I'm getting a bad but sporadic miss that according to the stealership is the 3 cylinders on the right bank dropping in and out. Driving down the road you can feel them drop out and when they come back its a kick in the pants like a turbo kicked in.
Shop says wires are good, plugs are good, and then lost me when they started talking around in circles and not making much sense.
What could make 3 cylinders all on the same side of the engine drop in and out? This wasn't anything that slowly came on. Fine one day, crap the next. The only thing I did prior to was replace the IAC because it was idling high, it was cruddy inside, and it looked like it was original. It was running fine after that till this issue popped up out of nowhere.
Mileage was claimed to be 178k but I'm beginning to suspect it's probably 278k.

I have late 2004 with 130k with a bpd egr cooler and new oil cooler and new ficm from Ed. Cat delete with no muffler. Everything else is stock I have a dash boss and was noticing some weird numbers. My check engine light came on but I couldn't get any codes with the dashboss. I started monitoring the egr error and saw some erratic readings really high negative numbers after I let the throttle off. The truck runs okay but was kinda starting slow. Could my egr valve be stuck? Could my short modified exhaust be messing things up?

I have the infamous ABS light & speedo not working on my 2000 Ranger. I replaced the ABS Speed sensor on the rear diff as has been suggested on many posts, but it didn't solve the problem. Did I get a bad part or is there something else I should go after?

so heres whats happening. My 98 ranger speedometer has not been working since I owned it (I am the second owner who got it from a grandpa) and I've replaced the vss sensor two times, got a new connector and gave that a try and still nothing. Yes I've looked for cracks in the wire or any exposed copper, I've looked through many forums and cant figure it out. At first before replacing the vss, my abs and check engine light weren't lit up until i put a new vss sensor on that i got from o'reillys, so then i got another one thinking it was just a bad sensor and still no luck. another thing is when its cold in the morning and i get in my pickup to go to work it will start working once i go over 30 and fluctuate between that and 20 but if i don't accelerate it will not bounce all over the place.

Last 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.

I have '90 Ford Ranger 2wd standard cab long bed. A few days ago the speedo stopped working. What is the more likely cause? The gauge itself or a relay/cable. And if it is the cable/relay are they hard to remove & replace.

1999 (built late 1998) Ranger 2.5 stick 2wd single cab. If I get much over 75 MPH the speedometer will reverse direction despite increasing speed. If I then let off the throttle completely, the speedo will jump right back up and indicate the correct speed. Continued operation without letting off the throttle to let the speedo recover will trip the ABS fault light, probably due to the erratic signal.
Disconnecting RABS module has no effect on symptoms. Speed sensor in the rear axle has been replaced already (by me) and the new unit ohm'd out good. Wiring between GEM and sensor checks out as well, good continuity (< 1 ohm) and no shorts to chassis ground. I wish I had an o'scope to take a look at the waveform, but I don't at the moment. It is on my future tool purchase list.

The "Check Hybrid System" message came up on my dashboard. I took it to the dealer, and they said the temperature sensor on the transaxle was giving erratic readings. Unfortunately, they said that the only way to fix it is to replace the entire transaxle. They said I could keep driving it and that it would probably go into disabled mode before it caused any more damage. What I should do? It's a rebuilt 2012 Prius with 25k miles.

Sold my mazda and got a nice 2000 2wd Ranger XLT with a 3.0L. Today the wife I and took it to town, 10 miles on the highway there, a couple in town and 10 back, didn't notice anything unusual. However I haven't this truck long so I'm not sure what is usual.
Parked it for a few hours and when went out to change the front turn signals to LED I noticed the ABS light was on when I drove it into the garage...
I checked fluid, connections and fuses, no change.I go ahead and swapped the bulbs while letting things simmer, I've had so many of these Fords sometimes the easy fix comes to me.
I backed it out and took it down the road, right away I noticed my speedometer wasn't working, so I let off the gas, when I re-applied the pedal I got nothing, like it was in neutral.
I downshifted to second and got her down and turned around as the O/D started flashing... (so glad because I would have hated walking back), then pulled her back in the garage to check transmission fluid and recheck fuses, including the ones I forgot earlier under the hood. I added a 1/4 qt of fluid then tried a road test again, this time there was a real long pause before it upshifted hard and the CEL came on.
I pulled the codes with my scangauge and got:
P0500
P2120
P0028
And decided I better look some things up and consult the gurus here before I do anymore damage tonight. I'm guessing that I'm looking at a tranny replacement possibly, but with the ABS light and speedometer failure I'm not 100% sure what is going on here...

1998 Ranger... I started having Speedometer/odometer problems after a power surge when my alternator went out. I knew the alternator was going bad and I tried to limp home another 5 miles rather than pay a tow bill and the alternator overcharged for a few seconds before completely dying. Since that time the only problem I am left with is my Speedometer and odometer have not worked. Scan tool says p0500 and I have replaced the ABS sensor on the differential with an OEM part but still no speedo or odo. I have checked all the fuses and relays associated multiple times. I do suspect that the RABS resistor is bad but there is no ABS light and it doesn't make sense that this one resisitor is the sle key for the whole speed control circuit. It's a manual transmission and RABS only. I swapped out the Cruise Control Servo with no luck as well. I am running out of options before having to take it to a dealer because I have to pass inspection. I have also checked and there is no power coming to 679 (GY/BK) into the instrument panel. I have also checked continuity for the rear harness to the ABS sensor and it is good.

so i changed the speedo cable and speed sensor in my 93 ranger, but still getting the speedometer bounce. what could be next? the speedo housing in the cluster? lubed the inner cable, made sure nothing is kinked or sharp bends. Put in a new vehicle speed sensor while i was at it just bcuz. cruise control does not hold a steady speed either but i think the 2 are not related. I'm leaning towards the cruise control servo as to why it does not hold a steady speed. Most of the time once i get to around sixty i'm basically driving by ear bcuz the speedo bounces from 60down to 55 and back up.

I got a 1997 Ford Ranger 2.5L that randomly jerks on the highway and I can't figure out what the problem is. This morning I had a 3 hour drive and it was fine on the first hour and then the last 2 hours it will randomly jerk on the highway and then be find for a little bit and then do it again. I don't know what the issue is? I did scan my car this morning and did have two code P0141 and P0113 not sure if these would have anything to do with it or not. Also my speedometer is hit or miss when it works, other than that everything else is fine on the car no check engine light or anything like that.

About a month and a half ago I was doing 70mph down the highway and the truck began to lean out sputtering and sounding like fuel was not getting there, when I pulled over on the side of the highway because it killed itself and then the car would not start I noticed the ox sensor for the 3rd cat was ripped out from being caught on the driveline, I removed ox sensor and car still wouldn't start. I took the truck to my buddies shop and after a new ox sensor was installed with some effort the truck started 30minutes later, I did not think this was reason for the truck to not start but after a day it was running like a top again, little did I know. Last week driving down the highway ironically in the same spot as before the truck did the same thing sputtered to a stop and would not restart.
Side Note: on both of these occasions after the truck would sit for a day it would start run for about 5 seconds and die???? So I had it towed home again and began reading FTE, I saw posts about fuel pressure and spark and P0176 code for Flex Fuel, Inertia Switch and so on.
So I started with Fuses they all look good then the most popular post and 2 of the codes were P0176 and P0177 for flex Fuel they read OBD II flex fuel wont start....Another code was for EVAP and 3 codes for heater bank(it turned out to be a fuse but is or could something trip this to send the car down this path?
I Then figured I would try the Fuel Filter..This did not work.
2nd I tried was Fuel pump pressure is good based off others posts.
So I bought the Flex Fuel Replicator that eliminates the need for the flex fuel sensor, from the guy in Portland, well this didn't work either. Next I went to spark checked all plugs they smelled like gas and were slightly fouled I had just replaced these about a year ago but hell why not? so I replaced and got nothing still also checked the oil had some gas smell to it but my buddy said this was normal with trying to get it to turn over without success.
Checked inertia cut off it was normal, checked fuses they were good(except heater which has been replaced). Now I am stuck...
