If you have a scope capture of what the sensor output roughly looks like,
I can grab some sensors of the scrap engine pile and you could easily
cobble something mechanical that is powered by a small electric motor or <?>
Befored you so kindly helped me with my project, I was ready to go that route.
Mechanical solutions to generate test signals aren't always a bad thing,
they are just lower tech.
