P1409 · ChryslerEGR Vacuum System Leak

P1409 on Chrysler vehicles indicates that the engine computer has detected a leak in the vacuum portion of the exhaust gas recirculation (EGR) system, meaning the EGR valve is not receiving the vacuum signal it expects. The computer typically monitors the EGR vacuum transducer or solenoid circuit and compares commanded vacuum to actual vacuum via a sensor, flagging the code when the two do not match.
