VSS Question
How many pulses per mile does the VSS generate? Is it the same in all years? I'm assuming it's a 12v signal too, is that correct?

It's 2000 or 4000 depending on the engine. I've already forgotten the specifics, but I think it's the SD TPIs got 4000ppm, and the MAFs and TBIs got 2000, but again, I'm not totally sure. I can check the book when I get home.
