A plurality of pressure sensors are carried in housing mounted upon a hydraulic control valve for an electro-hydraulic brake system. The pressure sensors are electrically connected to a signal conditioning circuit which also is mounted upon the hydraulic control valve. The signal conditioning circuit samples the sensors and mulitplexes the sensor signals into a single output signal.
