Abstract
Various embodiments include a method for monitoring a pressure sensor in a hydraulic system of a motor vehicle, the method comprising: actuating a valve of a pressure accumulator in the hydraulic system; detecting a behavior of the actuated valve in response to the actuation; determining a time offset of the actuated valve based on the detected behaviour; determining a measurement value of the pressure sensor; comparing the time offset of the valve with the determined measurement value; and checking a plausibility of the measurement value based on the comparison.
