How do you fix code po401 on 03 lancer?

Error code PO401 on a 2003 Mitsubishi Lancer typically indicates an issue with the EGR (Exhaust Gas Recirculation) system, often related to insufficient flow. To fix it, start by checking the EGR valve for blockages or damage and clean or replace it if necessary. Additionally, inspect the vacuum lines and passages for any leaks or obstructions. If these components are in good condition, further diagnostics may be needed to check for issues with the engine control unit or related sensors.
