Abstract: Systems, methods and apparatus are disclosed for disabling control of one or more outputs of an internal combustion engine system in response to an engine-out NOx sensor during a high frequency pressure pulsation associated with the exhaust gas at the engine-out NOx sensor. A high frequency pressure pulsation event may be determined in response to a pressure sensor measurement, or in response to operating parameters of one or more components of the system indicating high torque output conditions, and/or by a blade position of a turbine adjacent the NOx sensor indicating passage of the exhaust gas pressure pulsations to the NOx sensor.
