Code P0401 indicates insufficient exhaust gas recirculation (EGR) flow in a Dodge Avenger. To fix this issue, first, inspect and clean the EGR valve and passages to remove any carbon buildup. Additionally, check the EGR system for leaks, ensuring all vacuum lines and connectors are intact. If the problem persists, consider replacing the EGR valve or the EGR vacuum solenoid as needed.
