Lazy is a term usually applied to old, high mileage 02 sensors not terminals on a CKP connector. Better to say lacks continuity. Chrysler had such a big problem with the connector terminals going to the solid state relay for the electric fans they made an upgraded connector available at their parts counter. The teminals would get loose and start to arc because a fan motor is high current which a CKP is not. If a CKP connector is intermittent the results are going to be much worse than a loose connection at a fan relay. You can also see the CKP pulse using a low current clamp on probe connected to your DVOM. I've corrected crank, but no starts on Ford and Lincolns by just pulling the CKP connector and spraying them with electrical contact cleaner. Years of dirt and smegma can result in a poor connection.
