  • VSS Signal

    Is the vehicle speed sensor signal a voltage, a pulse, a current, or something else?

    How does the pcm know how fast the car is going- what exactly does it read off the VSS?

    Its a magnetically created pulse. The old VSS was only good from 0-255mph (8bit) but I think the new ones are a lot more accurate and are 16bit.

      Re: VSS Signal

      ressurecting this post...

      i changed my Tranny from a 1994 t5 - 2000 t5. the problem is the VSS is different now. i got the right plug for it...plugged it in and the speedo is goin whacko - at 8mph the speedo says im doing 80. i topped the speed governor @ a whopping 15 mph!

      so any thoughts on how i could adapt this to work for my car? resistors - etc...

      any help would be greatly appreciated as i dont have the time/money to adapt the old VSS to the new sensor.

      thx.

          annnd if that isnt an option?

          i.e. - if the tranny currently in the car cant use the old sensor...

          what then.

              there completely diffrent pulse patterns . not interchangeable.

                the problem is that the sensor in the 2000 trans is an effect sensor like the camshaft position - whereas the old vss in my 1994 trans is a gear driven sensor.

                i cant use the original sensor with the new trans due to the fact that it would have nothing to drive the sensor.

                any ideas?
