Abstract: Nitrogen oxide multiplexing systems are provided. Various embodiments provide for systems comprising an aftertreatment component configured to treat exhaust exiting an engine, a sensor, a conduit, and a switching device. The sensor is configured to detect nitrogen oxide in the exhaust from both upstream of and downstream of an aftertreatment component. The conduit has a first end positioned upstream of the aftertreatment component and a second end communicable with the sensor positioned downstream of the aftertreatment component. The conduit receives a sample of the exhaust flowing from upstream of the aftertreatment component through the first end and delivers the sample of the exhaust to the sensor through the second end. The switching device is connected to the conduit and configurable to selectively prevent the flow of exhaust upstream of the aftertreatment component from reaching the sensor.
