A control system and method for an exhaust gas recirculation (EGR) system of an engine includes a first sensor that senses fresh mass air flow, a second sensor that senses charge air flow, where the charge air flow is based on the fresh mass air flow and EGR exhaust flow, and a calculation module that determines a difference between the fresh mass airflow and the charge air flow and generates an EGR valve control signal based on the difference.
