The stepper motors on the dash board instrument panel are bad. There was faulty motors and you can buy them on ebay. In order to replace them you have to take the instument panel out, (go to youtube for the video) then you need to unsolder the old motors and solder the new ones in. I had never done something like this and took about an hour to replace two motors one on the gas guage and the other on the speedometer. They take the same stepper motor.

How do i replace the speed control sensor


The speed control sensor or VSS is located under the vehicle in the right rear corner of the engine compartment. 8c29507b-5bfa-404c-86dd-172009823d72.jpg

Speedometor quits working


Sounds like your VSS. Vehicle speed sensor. I don't have that year vehicle, but my older Prelude did the same thing.

What is the function of the speed sensor?


The speed sensor would be a likely suspect.
It takes the place of the speedo cable going from the transmission to the speedometer.

Subaru 97 speed sensor trouble code p0500 not passing admissions.. what part to I buy and where is the sensor located?


There are actually two Vehicle Speed Sensors (VSS). I'm going to assume you have a 2.5 liter engine and an automatic transmission.

The Vehicle Speed Sensor 1 (output shaft rotation sensor) is mounted to the extension case (from the outside of the case). The sensor outputs a pulse signal which is transmitted to the TCM where it is converted to vehicle speed.


The transfer clutch drum is connected directly to the rear wheel driving propeller shaft. Vehicle speed sensor 1 on the AWD model detects rear-wheel speed.

Vehicle Speed Sensor 2 provides vehicle road speed information to the ECM. The ECM uses this data to properly determine ignition and fuel delivery curves. The sensor consists of a reed switch and magnetic rotor turned by the speedometer cable.


One rotation of the magnetic rotor opens and closes the reed switch four times, producing a digital signal which is converted to vehicle speed by the ECM. The sensor operates whenever the vehicle is moving with ignition ON. As the transmission rotates, the speed sensor sends a pulsed on/off signal to the ECM.

The speedometer uses VSS 2 for it's signal.

Hope this helps (remember to rate this answer).

Fuel gauge fluxuates and speedometor does not


sounds like you have a cluster problem, you checked the cluster fuse in the fuse panel? If fuses are ok it may be a more serious problem right inside the instrument cluster

My tranny is slow shifting and the s light is blinking


The "S" light flashing means the speed sensor went out. Is an easy fix. I got mine for less than $40 and it was not hard to install. As for the gears going in too slow, I dont know. Good luck.

Speedometor


your tire size will throw it off if they are bigger then stock,and if that's not the case then you a just bring it to a garage and get it calibrated.
