A system and method determine the position of an elevator car movably arranged in an elevator shaft of an elevator system. The system has a 3D sensor, an evaluation unit communicating with the sensor, and a marking element. The sensor has a plurality of sensor cells and the evaluation unit uses measurement data received from the sensor to determine a distance from each sensor cell to a part of a detected object. The sensor is arranged such that in a normal mode of the system it detects the marking element as the object. The evaluation unit determines the position of the elevator car in the elevator shaft based on distances from sensor cells to the detected part of the object, continuously performs a test as to whether the sensor detects the marking element and brings the system into an error mode as soon as the test is negative.
