I have a 99 Legacy with a faulty Speedo. I've searched the threads, but have not found the correct voltage outputs from the sensor. This is on a manual trans, single connector with three pins.

 

Thanks, Larry

That is because it is not a voltage, but a signal. sort of like :

 

_|-|_|-|_|-|_

 

Well, something like that. the more ticks per second, the more speed, and the higher the needle goes. At least that is what goesw into the ECU. I'm sure that the guage uses something similar.

Yeah I got the same thing which has been fixed and still doesnt work. SOA is gettin a nasty letter but this except I have to go buy a 2 cent stamp. What a world.

I pulled the VSS to drive it by hand and check the speedo and the VSS broke in two. After installing a new one and tightening the screws that hold the speedo to the dash all is Fine.

 

For owners with this problem, it may be worth a try to remove the dash and then one at a time remove clean and reinstall the 5 speedo screws.
