It depends on the crank sensor, the two wire sensor puts out an ac signal, that signal goes to the ignition module, the ignition module converts that signal to dc, the computer can't handle ac. You can get a signal with dmm set on dc, even though it puts out ac signal. I've seen it. Maybe it is reading dc one way and then dc the other, I don't know?
The hall switch crank sensor, three wires, is a dc signal, on the signal wire.
