Abstract
Methods and systems are provided for utilization of vehicle speed and barometric pressure sensors. In one example, a method may include measuring a change in a barometric pressure resulting from a measured change in a vehicle speed, modeling the change in the barometric pressure based on a change in a ram-air pressure resulting from the change in the vehicle speed, and indicating a degraded barometric pressure measurement when a difference between the measured and the modeled change in the barometric pressure is greater than a threshold pressure difference.
