The speed sensor is located on the transmission towards the tail shaft. The housing that encloses the cable will attach on the side of the tranny. At this connection you will find the speed sensor right where it attaches to the tranny. There will be a couple of wires attached to the speed sensor.

My 1996 saab Turbo 9000 CSE turbo recently the speedometer and odometer stopped working, car felt like it would drag slightly while driving, then they started working again. Why?


those units are connected to the VSS sensor which also reports to the TCM for ratio changes
run the fault codes and see if the VSS is in the codes

Speedometer won't work in 97 Astro, replaced sensor..help


What sensor ? VSS - vehicle speed sensor on the transmission ? Colud be the speedometer gauge is bad . Do you know how the insturment cluster get's that info. ? Your best bet , take it to a qualified repair shop . You have no idea how it works , don't have the diagnostic tool's to find the problem ,so do yourself a favor . The first step would be to hook up a factory or professional type scan tool to see if the VSS info is seen in the VCM ,then to see what the VCM is sending over the serial data network . Do you know what a serial data communication network is ? VCM is vehicle control module .
Speedometer and Odometer Circuit Description
An electronic speedometer is standard equipment on all models. Integrated circuits control the air core speedometer and the stepper motor odometer. Removable bulb and socket assemblies provide the lighting. The socket assembly inserts into the back of the instrument cluster.
The speedometer system consists of the following components:
• The instrument cluster
• The vehicle speed sensor (VSS) calibrator
• The VSS
• The related wiring
The VSS calibration is part of the VCM that changes the analog output from the VSS to a digital signal. The digital signal contains 4000 pulses per mile (PPM) for the instrument cluster. The VCM sends the signal to the speedometer through CKT 389. The VSS calibration matches to the final drive and the tire size of each vehicle. Reprogram the VCM with the proper VSS calibration if the final drive or tire size changes for any reason. The signal will not be accurate for the proper speedometer/odometer operation if the necessary change is not made. An incorrect VSS calibrator can also affect the following components:
• The antilock brakes
• The vehicle control module (VCM)
The cruise control systems
The VSS calibration is programmed into the VCM. Do not service the VSS calibrator separately.
The VSS is a permanent magnet signal generator that sends an analog signal proportional to the propeller shaft speed to the VCM. The VSS mounts to the transmission tailshaft extension housing on the two-wheel drive model. The VSS mounts to the transfer case output shaft housing on the all-wheel drive models.


Use a Scan Tool in order to read the vehicle control module (VCM) diagnostic trouble codes.
Are there any vehicle speed sensor related trouble codes?

My speedometer reads fine up to 38mph, then stops. The odometer works fine, and the cruise works fine. Any ideas on the Speedometer?


didnt specify what vehicle -generic answer -is it digital or mechanical --check speed sensors if digital and the gears/cable connection if mechanical

Speedometer and odometer have stopped working. I have replaced the VSS and they still do not work


suspect you may have some sort of power issue. Check all fuses. May be a hairline crack in a fuse that powers the speedometer. If you can get a 12v light prove place negative of probe on car body and then put the probe pointy end on each side of each fuse to test each fuse .
google 12v probe.

They both work off of the same cable, so I would say that you have a problem in the speedometer head itself and will need replacing or sent in for repair.

Transmission speed sensor


You could have a faulty speedometer/odometer combination meter causing a false Vehicle Speed Sensor error.
My 1998 Sienna had the following symptoms:
- Speedometer and odometer failed intermittently
- The check engine light would come on and I would get a p0500 code in the OBDII.
- The cruise control would stop working at the same time the speedometer failed.
There is a speed sensor in each one of the tires and they feed the speed information to the ABS ECU. From the ABS ECU the speed signal goes to the speedometer/odometer combination meter, and from there it goes to the Engine Control Module and to the Cruise Control ECU. I could see a signal coming into the speedometer/odometer, but no signal going out. Replacing the speedometer/odometer combination meter fixed the problem.

Vehicle speed sensor location


The speed sensors they are refering to are located on your front wheels and are part of the ABS system.

SPEEDOMETER QUIT


You may need another speedometer. The speed sensor sends a signal to both the speedo and the odometer. So if the sensor fails, both meters would stop working.
The speedo gets power from the same circuit as the warning lights.
