Abstract
Various systems and methods are described for controlling a NOx sensor coupled to an engine exhaust system in a motor vehicle. One example method comprises generating an offset of the sensor based on an ambient air flow drawn into the exhaust system, the ambient air flow having circumvented cylinders of the engine, and adjusting an output of the sensor based on the generated offset.
