Pressure Sensor for a Vehicle

A pressure sensor for a vehicle includes a housing, in which at least one sensor unit is arranged. The at least one sensor unit determines a pressure difference between a pressure at a measurement connection point and atmospheric pressure. The at least one sensor unit senses the atmospheric pressure at at least two reference pressure bores. The disclosure further relates to a braking system for a vehicle, having at least one such pressure sensor. A sensor dewatering means comprises a connection channel, which connects the at least two reference pressure bores to each other.
