Abstract
Methods and systems are provided for EGR valve diagnostic. In one example, a method includes providing a correction to a position of the EGR valve to compensate for an altitude of the vehicle. The compensation is based on a comparison of a pressure ratio to a curve rationalized with a barometric pressure.
