Zusammenfassung:A combustion system (100), a control module (104) for a combustion system (100) and a method of operating the combustion system (100) are disclosed. The method may be implemented by the control module (104) in the combustion system (100). The method comprises predicting an iced condition of the pressure sensor assembly (240); responsive to predicting the iced condition, controlling exhaust emissions without using a pressure parameter sensed with the pressure sensor assembly (240) in the iced condition; predicting a de-iced condition of the pressure sensor assembly (240); and responsive to predicting the de-iced condition, controlling the exhaust emissions using the pressure parameter sensed with the pressure sensor assembly (240) in the de-iced condition.
