OG exemplary drawing
 
1. A vehicle system, comprising:
an olfaction sensor assembly comprising:
a housing including an inlet;
a blower disposed within the housing and configured to draw air through the inlet,
the blower separate from a second blower of a heating, ventilation, and air conditioning (HVAC) system of the vehicle;
a dehumidifier disposed within the housing configured to decrease a humidity of the air; and
a sensor disposed within the housing and located directly downstream of the dehumidifier and configured to measure an amount of carbon monoxide in the air after the air flows through the dehumidifier,
wherein the olfaction sensor assembly is disposed within a component of the HVAC system through which the blower of the HVAC system blows air; and
a control module configured to selectively take one or more remedial actions based on the amount of carbon monoxide in the air measured by the sensor.
