Abstract
Embodiments for estimating intake air humidity in an engine are provided. In one example, an engine method comprises adjusting an engine parameter in response to intake air humidity estimated based on a concentration of one or more engine-out emissions. In this way, one or more exhaust emission sensors may be used to estimate intake air humidity.
