The issues with your 1995 Buick Riviera's speedometer, erratic transmission shifting, and non-functional odometer likely stem from a failure in the vehicle's Vehicle Speed Sensor (VSS). The VSS provides essential data to the engine control unit for both the speedometer and transmission operation. If the sensor is malfunctioning or there’s a wiring issue, it can cause all these symptoms to appear simultaneously. Additionally, check the vehicle's fuses and connections for any signs of damage or corrosion.
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.
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.
you need to change the speedometer cause if your odometer is counting then speedometer should be working too. make sure your speed gear its working its in the side of the transmission The odometer and speedometer read off of the same signal. If one works, the signal is ok and the other gauge is bad.
check the vss located on the tailshaft of the transmission for the speedometer issue the odometer is figured out based on the speedometer also so it will quit as well. this sounds like either the sensor is bad or a short in the wire from it The cord for the speedometer came undone from the transmission or the gauge cluster is bad
You need to replace the speed sensor on the rear of the transmission.
Have your mechanic check the speedometer cable connections. They no longer use a cable. It is electronic. If the speedometer is not working but the odometer is, the problem is in the dash cluster. If both the speedometer and odometer are not working, the speed sensor in the transmission may be at fault.
The speedometer/odometer sending unit is located on the transmission tail shaft housing, drivers side.
There is no odometer/speedometer cable in that vehicle. The odometer/speedometer is electronic.
My speedometer works and the odometer does not because there is a plastic gear in the odometer that is broken.
In a Saturn, the speedometer and odometer often rely on different sensors to function. While the odometer tracks the distance traveled using information from the vehicle's transmission, the speedometer typically relies on a Vehicle Speed Sensor (VSS) for real-time speed readings. If the VSS fails or has a wiring issue, the speedometer will stop working while the odometer continues to function normally. Thus, a malfunction in the speed sensor is usually the culprit when the speedometer is non-functional but the odometer still operates.
There is not an odometer cable. The odometer is driven by the speedometer. If the odometer is not working then you will have to replace the speedometer head.
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.
