Since a small pulsed voltage is probably generated each time the magnet passes by (inducing a voltage into the coils of the sensor) a person might be able to mesure the output with a millivolt meter. Disconnect it at the coupler under the shifter coupler cover plate, and connect your voltmeter in place. Drive the car and see if you get a reading. Or, maybe check the continuity of the sensor itself (with an ohm meter). Anything more than a few ohms resistance probably means a bad sensor.
All conjecture, of course, but logic tells me this might be worth a try. I can't imagine the sensor itself going bad unless physically damaged. You may just have a break in the wire(s). Pull the whole damn unit out of there and take a look! Oh...and good luck!
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
