Hi,
I have a problem with 3800sc speedometr don't work.
All gauges works but not speedo. Do you have some VSS diagrams for grandprix
2002 gtp? There are two pinouts into vss sesnor - DARK GREEN 389 and SOME OTHER
, I dont know what is this sensor wiring. Does 389 wire goes into spedometer
directly?
Thanks:)

If you check the waveforms of the output of a Fiero VSS, and a GP VSS, you'll see they're quite different.
I'm assuming you're use the trans from the 2002? |

I'll email you the 2k2 diagram (it's a PDF, and you can't inline post those here).
The output on the Fiero is a sine wave. So it just depends on what time slice you're looking at as to which one is pos or neg. ;) As for the bonneville VSS output - you'll have to look more into it, but I was under the impression it had a square wave output, so you needed a signal converter. |
