Check VSS(vehicle speed sensor).Erratic communicating signals back and forth w/ the PCM can cause improper shift points,plus the inoperable speedometer points at that direction.
Most likely speedometer cable
I have the same problem hope someone tells us what to do Mel
You would fix it by replacing the instrument cluster. The speedometer itself may not be faulty, it is more likely to be a problem with the speed sensor.
There is no fuse just for the speedometer. If the speedometer is not working, you may have a problem in the dash gauges cluster, or a vehicle speed sensor problem.
not sure,,,,,,same problem here not sure if it ia a cable or eletronic. May be a relay or something. If I find out I will post
Cruise will NOT work if the speedometer has a problem
If a 1992 Honda Civic's speedometer is erratic, the problem could be the speedometer cable. It could also be the speedometer sensor malfunctioning. Check both components carefully.

check the wiring to the speedometer. Check the sending unit as well. If the problem is internal then the speedometer will have to be replaced.
There might be a problem with the cable.
Have vehicle scanned to determine the problem
Cable could be loose.
We had the same problem...there was a recall on this...check with your local dealer.
A speedometer that loses response time but gets up to the speed of the vehicle probably has a problem with a gear slipping inside the speedometer mechanism. This sometimes happens in older vehicles. The speedometer cable may have to be replaced to fix this problem.
Speedometer is ran by electronic sensor on rear end. Odometer is ran from speedometer. If both don't work problem is sensor. If speedometer works sensor is okay. If speedometer works and odometer does not problem is in mechanical parts (gears) of of odometer and has to be replaced. Can get used from eBay (search for speedometer or odometer, is one unit) or take to dealer.
If it's an electronic (analog) speedometer needle, you probably have a problem with the dasboard grounding.
Due to the nature of the problem 'irregular speedometer' it has to be repaired by a licensed mechanic.
It seems as if there is a problem with the wiring between your speedometer and AC/heat unit. A licensed repairman can determine and fix the cause of this problem.
Most common would be speedometer cable has broken Remove speedometer head and move vehicle to see if cable moves- if not probably broken - if it does probably problem with speedometer head
The problem is inside the speedo and has to go to a speedo shop to be repaired.
The odometer on a 96 Ford Explorer is tied into the speedometer. If the speedometer is working then there is a gear problem inside of the speedometer causing the odometer to not work.
If the speedometer and abs light are not working then you have a speed sensor problem. If the speedometer or odometer are not working then you will need to take it to the dealership and have them send it off for repair.
I have a vague recollection that the neutral start switch could be the problem.See "Related Questions" below for more
we had to replace the speed sensor in mine and it corrected the problem with the speedometer and the shifting. Good luck
If the speedometer in your Voyager is not working, you might have a problem with a disconnected cable or with the fuse to the display. You could also have an issue with a sensor.
