underneath the hood on the passenger side there is a fuse box. open it and check the fuses if they are dead replace them.

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.

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.

The VSS (Vehicle Speed Sensor) is located on the transmission. If the speedometer is not working, it is rarely the VSS causing the problem. I would first check fuses and the ECU

If both the speedometer and the odometer do not work I would suspect the VSS (Vehicle Speed Sensor) located on the tail shaft of the transmission is at fault. If only the speedometer doesn't work it's probably a problem with the dash cluster.

Its probably the vehicle speed sensor located on the transmission. Mine had that problem

Much appreciated if the problem solves.

There might be a problem with the cable.

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 are two speed sensors, an input and output. They are located on the transmission. If the problem is the speedometer not working it is the output sensor located on the driver side of the rear of the transmission.

Its is located on the transfer case. It pulls right off the transfer case and is very simple and easy to change...only problem is finding the gear to replace it

User Avatar

I am having the same problem. I know for sure there is one on the transmission but according to my mechanic there is another in the instrument cluster at the speedometer. Can seem to find any info on the speedometer sensor.

User Avatar

We had the same problem...there was a recall on this...check with your local dealer.

User Avatar

the problem is likely in the guage cluster itself because you are getting a good signal from the senser to make the speedo work

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.

If it's an electronic (analog) speedometer needle, you probably have a problem with the dasboard grounding.

User Avatar

Due to the nature of the problem 'irregular speedometer' it has to be repaired by a licensed mechanic.

User Avatar

your car has a speed sensor located on the transmission replace that and problem is solved

User Avatar

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.

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.

User Avatar

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

User Avatar

The problem is inside the speedo and has to go to a speedo shop to be repaired.

User Avatar

I have 3 possible solutions: first, replace the speed sensor. it is located on top of the transmission. if this didnt work, then try replacing the speedometer. last but not least, if all these failed, replace the ecm.

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.
