PSA P0441 Evaporative Emission System Incorrect Purge Flow
The P0441 diagnostic trouble code indicates an issue with the Evaporative Emission System Incorrect Purge Flow. A notorious code on Peugeot/Citroen (PSA) vehicles, mainly resulting from stuck evap purge valve. Found frequently across psa models utilizing 1.6 HDi, PureTech, THP engines, this code will illuminate the Check Engine Light and may cause the vehicle to enter Limp Mode to protect the mechanical components.
