if you unplug your map sensor while the car is running your car should turn off.
Am i even in the ballpark of this thread, I feel as if I'm talking about something completely different.
What's the problem?
You're confusing a tps with a map sensor. Tps is located on the throttle body. It's operated by the throttle plate, the more it opens, the more voltage the tps sends to the ecu to compensate for load.
Map sensor needs a vaccum line to sense manifold pressure and vacuum. More manifold pressure and less vacuum = higher voltage sent to ecu and vice versa.
