A method for updating an operating function of a sensor, which has a memory that has a boot memory area for storing a boot function and an operating memory area for storing an operating function. The method has the following steps: execution of the boot function; checking whether an update for the operating function of the sensor needs to be performed; if an update for the operating function of the sensor does need to be performed, performing a plausibility check; if the plausibility check was successful, updating the operating function of the sensor such that data for an up-to-date operating function are received from an external unit and the data are written to the operating memory area. The reception of the data and the writing of the data to the operating memory area take place in parallel.
