Abstract: A method and a system for the positioning of the elevator car and the door of the elevator in the condition monitoring system are provided. In the method the accelerations of the elevator car and the door of the elevator are measured with a sensor. By integrating the acceleration information two times in relation to time the position information is determined. When the condition monitoring system detects a fault, forecasts a malfunction occurring in the future or detects a significant change in the operation of the elevator or in the measuring signals related to the elevator, it is possible to attach to this information the location of the fault or event i.e. the position of the elevator or the position of a door of a certain floor level on the slide path. The position information can be synchronized to a separate reference point by means of a positioned switch by making an adjustment to the position information at the reference point.
