On my 2ooo FXDS TC, it was the engine Crank Sensor both times and not the cam sensor..
I don't know how to check them electrically but IF you pull the one on the engine (bolt out and wiggle out) and look at the end.. IF any metal is sticking on it or Look Damaged ?.
Hoople had walked others thru this, to check but I don't do that.
I am surprised it is there..Better BONE-UP on the bikes a bit..
