P0441: Evaporative Emission Control System Incorrect Purge Flow
22 vehicles · 12 makes · $15-$2,500 repair
Most Reported On
P0441 is an OBD-II diagnostic trouble code meaning “Evaporative Emission Control System Incorrect Purge Flow.” This code means the Engine Control Module (ECM) detected an incorrect amount of purge flow in the Evaporative Emission Control (EVAP) system. The EVAP system captures gasoline vapors from the fuel tank in a charcoal canister and then 'purges' them into the engine to be burned, controlled by a purge valve. P0441 sets when the computer commands the purge valve open or closed but sees the wrong flow — too much, too little, or none at the wrong time. It is an emissions/sealing issue, not something that usually affects driving, though you may notice a fuel smell. This code is most commonly reported on 2011-2023 Chrysler 300, 2007-2014 Toyota FJ Cruiser, and 2016-2023 Toyota Tacoma, plus 19 other vehicles, with repair costs ranging from $15 to $2,500.
