Air Quality Sensors

The air quality sensor assembly uses two sensors to monitor the quality of air in a vehicle's cabin: a Hydro Carbon (HC) sensor that detects gasoline exhaust fumes and a Nox sensor that detects nitrous oxide or diesel exhaust fumes. If the assembly detects poor air quality, it activates the HVAC system.
