摘要
A system and method to perform bypass actuation detection includes alternating control of a bypass valve within an exhaust gas recirculation (EGR) system of a vehicle to direct flow of gas through a cooler module or a bypass module within the EGR system. The method also includes determining a position of an EGR valve that directs the gas into the EGR system, and verifying operation of the bypass valve based on the position of the EGR valve.
