A yaw rate sensor (10) includes a movable mass structure (12) and a drive component (13) which is suitable for setting the movable mass structure (12) in motion (14), and an analysis component (15) which is suitable for detecting a response (40) of the movable mass structure (12) to a yaw rate (&OHgr;). A method for functional testing of a yaw rate sensor (10) includes the following steps: driving a movable mass structure (12), feeding a test signal (42) into a quadrature control loop (44) at a feed point (48) of the quadrature control loop (44), feeding back a deflection (40) of the movable mass structure (12), detecting a measure of the feedback of the movable mass structure (12), and reading out the response signal (47) from the quadrature control loop (44). In the yaw rate sensor (10) and also in the method, the readout of the response signal (47) in relation to a processing direction (45) of the test signal (42) is provided between a feed point (48) for a test signal (42) and an actuator (38) for feeding back a deflection (40) of the movable mass structure (12).
