Well I did a search just to see if this has been touched upon, and didn't see something that matches my issue exactly.

As stated in the subject, I've got a '00 Dakota, V6, that's it, no 4x4 or anything. It's just a plain automatic.

Now, here's the problem. Today I turned on my truck to find that my speedometer wasn't working. I had at first assumed that it was 'cause I was going under 20mph, but when I was following the flow of traffic and knew we couldn't all be going under 20 I got a little worried. I've since driven it a couple of times in the vain hope that it'd magically work.

No such luck. Tachometer still works which is helpful, but not the best. Now I've read some stuff about sensors...where are they at and are they easier to buy? I've got to drive back home tomorrow which is like an hour and a half drive from where I'm at.

And I'm guessing that the police won't sympathize to much for me if I accidentally speed on my way home.

Any advice and recommendations you can give me is greatly appreciated!

 

It has happen to me before, but it was in another brand of car.
Probably the cable broke down.

What i did when it happen to me to drive was, i used the tachometer to guide me, on how fast i was going.
usually it work 4 me.

 

Honestly.... how often do you actually not speed??? Just keep your eyes peeled for police and if you're really worried about your drive home just stay in the slow lane

 

Sounds like rear-wheel speed sensor is open. It is located on the top of the rear diff housing.
