I have the same problem on an '89 Dodge Dynasty. I am told that the odometer and speedometer in my car are driven by separate cables and that I simply need a new cable for my odometer to function properly again. I have not verified this information, but it might get you on track.

why would a speedometer and odometer not work on a suzuki motorcycle?

I would say you have a problem with the dash cluster. If both speedometer and odometer were not working I would say the problem may be the speed sensor but being only the odometer is out I would blame the cluster. I believe you will have to replace the cluster as a whole with a reconditioned unit. This will probably be a dealer item only.

check speedometer cable for possible disconnection; it comes out of firewall and goes to transmission

If both odometer and speedometer are not working I would blame the vehicle speed sensor. If just the odometer isn't working the gauge cluster assembly needs to be replaced with a reconditioned one.

If you open the odometer, there are two small plastic gears. One is connected to the speedometer, the other to the odometer. The speedometer gear drives the odometer gear. In all likelihood, one of these gears is missing a few teeth. I have the same problem with my Ramcharger, same year.

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.

The gears in the speedometer are stripped. If the odometer is working then you have input.

If the speedometer is not working but the odometer is, I would suspect the dash cluster is at fault. If both speedometer and odometer are not working I would suspect the speed sensor on the transmission is at fault.

If the speedometer and odometer are both not working, I would blame the speed sensor. If only the speedometer does not work and the odometer does work, the cluster is bad.

Probably a power spike, often when a Caravan is "jumped". Try pushing the odometer/trip odometer button for 4-8 seconds. When it starts running a diagnostic test the speedometer should start jumping around and then reset itself. If it doesn't last, you may have a bad circuit. If a 100.??? comes up, you have problem of some type, maybe related-maybe not.

The legality of replacing the odometer would be in question. I would take out the dash with the speedo and take it to a certified speedometer repair facility. Like stated before, I would buy a service manual or cd.

That depends on the year, make, and model. Most newer cars do not have a dedicated speedometer or odometer wire. The speed sensors are also used for shift timing. If it as old enough vehicle that has a dedicated speed sensor the speedometer and cruise would also not work. Some vehicles, such as 1998 on up Dodge trucks, use the abs sensors for the speedometer and odometer.

If both the speedometer and odometer are not working I would suspect the VSS (Vehicle Speed Sensor) is at fault. If the speedometer doesn't work and the odometer does, I would suspect the instrument cluster is at fault.

The speedometer and odometer are electrically operated. There is no mechanical connection to the drivetrain. If there is no power, they don't work.

Most likely the VSS. Vehicle Speed Sensor. It is mounted on the side of the transmission.

There is no speedometer cable on a 1995 caravan. it is done by a speed sensor on the transmission and digtal data is sent to the computer and the computer then sends the signal to the speedometer. This is the case even when the speedometer looks analog. Likely a bad speedometer is the cause if it does not move as the speed sensor is used for other functions and would trip the "check engine" light if it was bad. the speedometer is part of the instrument cluster and likely you would need to change the whole thing.

When those things on my 92 B250 did not work, I replaced the speed sensor located on the transmission tailshaft and that fixed the problems. Hope that helped! Mark When the speedometer and odometer did not work in my 1990 B250, I had to replace the speed sensor, instrument cluster (speedometer) and replace a tiny gear (odometer) in order to get them working properly

User Avatar

If the abs light is on, then you might have a rear axle speed sensor issue. If not, then you have a cluster problem.

if he doesnt know how then he must not be a very good mechanic, i have a 92 Spirit, same engine and trans as your caravan, that's if your packing the 2.5L engine... the speedsensor in the back should have the speedometer built
