instructions on how to replace vehicle speed sensor?
 

I am getting a 95 ram 1500 today or tomorrow, and it needs to have the vehicle speed sensor replaced. The dealership told me that there are two sensors, one on the rear end and one on the transmission. I can do this no problem, but I need a write up or something that shows me where the sensors are and what to do. Is there anything out there for replacing both sensors on a 95 1500?

Thanks

In a 95 is there only one Speed sensor, because my research on wholesalemopar only comes up with one sensor for $75, instead of two for 35 and 15. Is there another one I need to look for in addition to the one for $75.

So is there one or two speed sensors on a 95?

It is probably the one in the rear differential then. I have never changed mine before though. I had to change the one in my transmission but my truck is a 99. By looking at wholesale mopar I would say it is the one in the diff. I dont think it would be too hard of a job though. I would also assume that the 94-95 use just one sensor.

I guess I will just have to get the sensor and see if there is a similar one on the diff or on the tranny. We will see. Thanks man.

if your rear diff sensor is gone then your speedo will act funny and your abs & brake lights will come on. that sensor takes about 10~15 minutes to swap out depending on how many beer breaks you take.

Actually the speedo dosnt work at all, I mean it dosnt move one bit. I havnt ran the dash test, which might be a good idea to see if the speedo is still functional. No ABS light, just the CEL throwing a code 15.

Should I try the dash self test?

Beer breaks? Hell, I don't get more than arm's length from that puppy!

ahahahaha,,, gary, i'd expect you'd have one of those dual can holder hats with the tubes coming down.

frey, does your truck have abs? if you can, i'd swap the rear diff sensor anyway, they are a common failure and will kill your speedo and possibly may contribute to your other problem. if the pcm doesnt know your speed, it will do funny things for sure.

lol who doesnt... im in the market for a postive pressure alcohol dispensing unit to allow for inverted angles and allow for succesfull delivery while in awkward positions.... or live lined to a keg sitting in a kegerator and a mouth peice for hands free use.. between a 10ft and 20ft line for mobility.. engeering plans are in the works :D


IIRC its union by-law.. dodge ram gear heads ,, local 360... that each mechanic is entitled to one beer break for every nut/bolt/cable/or part uninstalled or reinstalled.. ill contact the rep for confirmation..


if your a new dodge ram owner.. i would STRONGLY suggest in investing in a hanyes or chiltons for your year.. priceless tool..and if anyone has the link to steves xmass gift last year.. theres a dl'able version for an 00-01 in PDF format that will come in usefull since alot of the information is interchangable....

good luck!

You forgot that all jobs must begin with a beer before starting any work.

The downloadable manual is in the "SEC. GEN RAM INFORMATION" thread at the top of the forum.

Isin't there a speed sensor somewhere near the motor, that's attached to a speedo cable type, setup?

Rear Speed Sensor Removal/Installation

1.Raise vehicle on hoist.

2. Clean sensor, cover, and sensor mounting area of axle housing (figs. 16 & 17). This is necessary to prevent dirt entry when sensor is removed from housing. Mopar brake cleaner or carb cleaner are equally acceptable for cleaning purposes.

3. Disconnect harness wires from sensor (fig 16).

4. Remove screw that secures brake cable, brake line, sensor cover, and sensor in axle housing (figs 16 & 17).

5. Remove sensor and cover.

6. Cover sensor opening in axle housing to prevent dirt entry.

7. Insert sensor in axle housing opening. Then position cover over sensor, and install cover and sensor attaching screw.

8. Connect harness wires to sensor and lower vehicle.





Those are the steps for the rear sensor, verbatim, from a 95' manual. If you have 4 wheel antilock, you will have sensors up front also. (each wheel).

I hope this helps. If you need front directions, PM me. Sorry about the blurry pics. I'm the Diesel Demon.....not a nerd like Mayfair...............(wink).

Ok, good luck.

No speed sensor in the diff of the 95, its in the tranny tailshaft

Thanks for that info and especially the picture, that is exactly what I was looking for. I figured since I could only located one part number for the vehicle speed sensor on wholesalemopar, that there was only one, and I wanted to verify. Thanks for the help, I will probably price the part at the local stealership then if it is a substantial differance I will be ordering from wholesalemopar.

Is there a possibility that my speedo gear might be busted? If it is how hard is that to replace, do I have to rip the rear of the tranny appart?

Thanks
Fry

RE: instructions on how to replace vehicle speed sensor?
 

It turns out, from talking to the stealership, that there are two sensors for a 95. Just like the other years, it has one in the tranny and one in the rear diff. Now, since my ABS light is not on, they said only replace the one in the tranny, and that is what my research on here says also. Gonna get the part in bit

RE: instructions on how to replace vehicle speed sensor?
 

yeah but you said your speedo didnt work... points to the rear. unless you have a cable for your year.

RE: instructions on how to replace vehicle speed sensor?
 

Right. The stealership told me that since my ABS light isnt on, then the problem is most likely coming from the sensor on the tranny. If the sensor in the rear was messed up my ABS light would be coming on too. Thus, since there is no indiation of ABS issues (dash light) then the sensor on the tranny is the culprete. Also, there could be the possibility of the speedo gear in the tranny being broke. If that is the case, the sensor might not even be bad.

RE: instructions on how to replace vehicle speed sensor?
 

well let us know what you end up finding.

RE: instructions on how to replace vehicle speed sensor?
 

I believe the "sensor" on the tranny output shaft IS the gear assembly. Otherwise ... 95s would have three speed outputs (rear, VSS and gear). Changing the gear is how one compensates for tires on the older models ... that means that the gear output is what drives the speedo.

RE: instructions on how to replace vehicle speed sensor?
 

I'll have to call Dodge and let them know that their manual is wrong. Must be the "SPEED SENSOR" and all the instructions to remove it in the REAR AXLE, were just a misprint.

I'll have to mention that the section on the FRONT SPPED SENSORS must be wrong as well.......LOL.



No wonder the book is so thick, it has the wrong info.

RE: instructions on how to replace vehicle speed sensor?
 

Well, I just found out another thing with the truck. Since I just got it yesterday I noticed Overdrive isnt working. Going roughly 70 miles an hour (gauged on the way to work this morning with flow of traffic on I-81, they always go 70ish) I was taching about 2700 rpms in third gear. Not too bad if ya ask me. I do not know if the tranny was replaced with a 3 speed, which would mean the sensor in the tranny would not be there. I do not know what gears might be installed, but I know it has crazy low end grunt & torque.

If the tranny was replaced what could it be?
If not replaced, what gears do I probably have?

Should I try to get the tranny looked at before I try to fix the speedo, because they might be related, correct? or should I replace the sensors and see what happens. I mean, I would hate for there to be chucks of something flying around the tranny and obliterate the new sensor. It dosnt sound like there is a tranny problem, sounds great actually. I guess it could be an electrical problem.

Anyone have any input about this.

Thank
Fry

RE: instructions on how to replace vehicle speed sensor?
 

Hell yeah! UPDATE

Last night I took my truck to my buddies house to replace the ball joints because I was told that they were bad...one of the reasons I failed inspection. Well after we got the truck in the air, we figured out the damn joints didn't need replaced after all. No noise when I messed with the tires, she is solid. Then I went to tear into the VSS sensor and gears. I pulled the sensor off, which looked 100% brand new...pulled the speedo gear pinion. These parts all seemed find. Then we took a drill and spun the gear in the transfer case and watched the speedo go up and down. We weren't too sure about why it wasn't working and I was just going to replace the sensor, but on my way home everything started working. The speedo works now, odo and tripodometers work, and overdrive works now too. I am so happy everything is working now.

Now I just have to save up some money and get my 3" Fabtech lift.

Thanks for the help guys, it was much appreciated.
