Method and system for a humidity sensor in a vehicle
First Claim
1. A vehicle comprising:
- an air intake for an engine having a humidity sensor;
a system having a reservoir fluidly connected to a nozzle positioned in the air intake; and
a controller configured to activate the system to deliver fluid from the nozzle into the intake for evaporation therein while the engine is inoperative and generate a diagnostic code in response to a change in humidity measured by the sensor being less than a threshold value.

Abstract
A vehicle includes an engine air intake having a humidity sensor, and a system having a nozzle positioned in the air intake and fluidly connected to a reservoir. The vehicle has a controller configured to activate the system to deliver fluid from the nozzle into the intake while the engine is inoperative and generate a diagnostic code in response to a change in humidity measured by the sensor being less than a threshold value. A method of controlling a vehicle includes measuring a baseline humidity (H1) using a humidity sensor in an air intake of an engine, and controlling a misting system to mist fluid from a reservoir into the air intake and adjacent to the humidity sensor while the engine is inoperative. The method measures a post-fluid delivery humidity (H2) using the humidity sensor, and generates a diagnostic code based on a comparison of H1 and H2.
