Ooops - my bad. The newest machine I have is an '01. Did not know that the design was changed since.
Anyway, discounting the above discussion about inaccuracy of the indicator, you stated that after the swap it stopped working altogether, right?
If so, presuming you did not work on anything else, the suspect items are what you touched, that is the sensor and the wires. I am guessing that you did not open or reconnect any jumpers or connectors, right?
Once the gap is confirmed, I would say that the sensor did not fail - it is enclosed and rather sturdy. It is quite likely that a wire broke in the sensor cable. I would suspect the connecting cable: it does flex, it is stressed and it is normally squeezed by a tie-wrap.
I do not recommend that (NO!), but if it happened to me, I'd figure that there is not much to loose and I'd cut open the jacket of the sensor cable. I do not know if it is just a magnetic pickup coil or a Hall sensor (maybe someone can chime in), therefore checking continuity through sensor may not work. I'd split the cable by the sensor itself and then as high up swingarm as possible and hope to find broken cable. You may just get lucky - and then fix the open jacket with electrical tape: ugly, but effective.
Any luck in the meantime?
