A connector system is provided that includes an electrical connector having a housing, a connector position assurance (CPA) element, and an actuator. The housing defines a socket that receives a mating connector. The CPA element is slidable relative to the housing between a released position and a locked position. The actuator is mounted on the housing in operable engagement with the CPA element. The actuator is moved from a blocking position to a clearance position as the mating connector is loaded into the socket. The actuator in the blocking position mechanically blocks the CPA element from being moved between the released position and the locked position. The actuator in the clearance position allows the CPA element to be moved between the released position and the locked position. The actuator attains the clearance position responsive to the mating connector being fully loaded in the housing.
