1. A vehicle, comprising:
a component coated with a pollutant reduction catalyst configured to remove pollutants from a flow of air over the component;
a catalyst temperature sensor coupled to the component;
a general temperature sensor;
a vehicle speed sensor;
an active grille shutter (AGS) system having a plurality of movable grille shutters; and
a controller configured to determine an efficiency of the pollutant reduction catalyst based on signals from the catalyst temperature sensor, the general temperature sensor, the vehicle speed sensor, and the AGS system,
wherein the catalyst temperature sensor includes a sealed housing permanently fixed to the coated component, wherein a presence or absence of a signal from the catalyst temperature sensor to the controller indicates a presence or absence of the coated component and thus the pollutant reduction catalyst, to thereby facilitate confirming the presence of the coated component for diagnostic purposes.
