Abstract
Systems and methods of monitoring redundant vacuum sensors in the same vacuum chamber of a braking system to determine when an error condition is present in a braking system. The braking system includes a first sensor positioned in a chamber of the braking system and a second sensor positioned in the same chamber. A first reading is received from the first sensor and a second reading is received from the second sensor. A difference between the first reading and the second reading is determined. An error condition is indicated when the difference between the first reading and the second reading is greater than a threshold.
