The invention relates to a method for operating a sensor device (2) in a sensor arrangement (3) including multiple sensors interconnected by a common communication line (7), comprising the steps of: - serially transmitting data on the communication line (7), wherein data are transmitted on the communication line (7) by applying a sequence of electrical levels, wherein the electrical levels include one dominant level and one or more subdominant levels, wherein only the dominant level is capable of overriding subdominant levels on the communication line (7); - monitoring the communication line (7); and - interrupting the transmission of data and/or blocking the transmission of data, in case a dominant level exists on the communication line (7) which has not been applied by the sensor device (2).
