Take to local shop have them Run a ABS scan they can tell you why. Cost is approx $80.00
The sensor in the differential may be bad. Also the wires going to the sensor may have rubbed against a brake line causing them to short. The sensor in mounted on top of the differential and reads the vehicle speed.
plugs into the rear differential
If your odometer/speedometer stopped working, then you must replace the "vehicle speed sensor" located on top of the differential if your have a manual transmission.
If an input output sensor has gone out, it will affect the functionality of your speedometer. If only the input sensor is affected, the speedometer will work with limited functionality. The output sensor will cease the speedometer from working completely.
There is no speedometer cable. MPH is calibrated using a speed sensor. If your speedometer is not working, you have a bad speed sensor module.
# 11....it controls the instrument panel....speedometer could be a seperste issue involving the speed sensor in the differential.
You may need to replace the speedometer fuse. The speedometer cable can cause your speedometer to stop working. The speed sensor can also cause the speedometer to stop working.
could be the speedo cable?
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.
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 the odometer are not working, I would suspect the VSS (vehicle speed sensor). If only the speedometer is not working I would suspect the instrument cluster has problems.
When this happened with my '00 Civic, it was a malfunctioning vehicle speed sensor (VSS). They typically fail any time after 115,000 miles. The part should be on top of the differential housing.
