if you want to test the wire going to it you will have to do a continuity test (buzzer) and connect the mumtimeter to the crank sensor pin outs at the ecu plug end and then to other end of the in the engine bay (plug)

just repair the wire as normal (soilder and heat shrink) but make sure the outer shroud is insulated from the inner wire at the point of the repair.
