EDIT* Not sure if I was clear enough.It's highly unlikely the pin is at fault , more likey the part it mounts into is warn in the vss so spinning freely.If you get what I mean ;-P
I took my honda one apart and compared it to my new £7 from ebay and they are virtually the same.And even if it lasts half as long it's 40X cheaper so no quarms replacing it again if it goes

.
Some of the forums suggest reusing the pin from your old vss but I was more comfortable using the new one as it was machined for the oem vss
There's 3 wires for vss . Should be 12V , ground and 0-5v pulse when in motion on the signal wire .Hope that helps mate.
