Does the odometer work?If so the priblem is in the circuit board in the instument cluster.The resistance on both wires going to speed sensor should be 5 ohms or a little less.If it is greater than that you probaly have a bad connection at pcm or a bad cluster.

I have a 95 grand marques the Speedo and odometer have stopped working I have already changed out the vss on the output shaft of the trans twice for the thought of possibly buying a junk sensor but to no...


Without a scan tool to confirm the BCM is getting good signal from the VSS, it's a risk. Since you've already replaced the VSS, it's time for a rebuilt cluster. DON'T buy a junyard unit. The rebuilt ones are fully refurbished and come with a warranty. Do a search for instrument cluster rebuilders.

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?

1997 Chevy Lumina the speedometer quit working and now it will not shift over while driving what could the problem be? It started yesterday...When the speedometer works the car drives fine bt then wi


could be the VSS - vehicle speed sensor .
Speedometer and Odometer
The Vehicle Speed Sensor (VSS) is a gear driven permanent magnet generator. The vehicle transaxle houses the VSS. The VSS generates a sine wave output with a frequency proportional to the vehicle speed.
The Powertrain Control Module (PCM) converts the CKT 389 signal to an output that switches to ground at a frequency of 4000 pulses per mile. The CKT 389 signal drives the speedometer and the odometer. Various other vehicle components use the CKT 389 signal. Refer to Engine Controls.

I have a 2003 Chevy Trailblazer with a malfunctioning tachometer and speedometer. What is the likely part I need to replace?


Sounds like a bad speedometer sensor. Usually located on the transmission. The only way to fix the speedometer is to replace the sensor.
The Variable Speed Sensor (VSS) has failed. You will have to get it replaced. Both are driven by an electrical signal sent to the cars computer by the VSS, and converted to SPEED, and DISTANCE driven.

well does it light up? if its an 89 I don't remember there being a digital offered
but the VSS (vehicle speed sensor) controls the speedometer its located on the transmission if its a 2 wheel drive and on the transfer if its a 4 wheel drive a scan tool (not a code reader) is your best tool to help you diagnose this one to see if the VSS is producing a signal to the Speedometer unit
