P0441 on Ford
Evaporative Emission Control System Incorrect Purge Flow
P0441 on Ford vehicles indicates evaporative emission control system incorrect purge flow. Au7o has documented this code across 2 Ford models — most commonly on F-150, Transit. 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. Typical repair costs on Ford range from $60 to $320, depending on the specific model and root cause.
Common Causes of P0441
- •Stuck-open or stuck-closed EVAP purge valve/solenoid
- •Failed or stuck EVAP vent valve
- •Loose, damaged, or missing gas cap
- •Cracked or disconnected EVAP/purge vacuum hoses
- •Faulty purge flow or pressure sensor
- •Clogged or saturated charcoal canister
- •Wiring or connector fault to the purge valve
P0441 on Ford by Model
Ford F-150(1 issue)
- EVAP Canister Purge Valve Stuck Open — Hard Start After Refueling, Rough Idle, P0455/P04962011-2020
The EVAP canister purge valve (purge solenoid) on F-150s commonly sticks in the open position, allowing raw fuel vapor from the charcoal canister to be pulled into the intake when it shouldn't be. This floods the cylinders with vapor — owners report a vehicle that cranks but won't start (or stumbles badly) immediately after filling the tank, then runs fine once it clears. A stuck-open or leaking purge valve, along with cracked/collapsed lines between the canister, valve, and intake manifold, is the most common trigger for P0496 (EVAP flow during a non-purge condition) and a frequent cause of P0455/P0442 large/small leak codes. Ford issued TSB 19-2132 covering loose EVAP hose connections on 2018-2019 trucks. The check-engine light is the usual first symptom; drivability impact ranges from none to hard-start/rough-idle. The real OEM purge valve part number is AU5Z-9C915-B (aftermarket cross-refs: Dorman 911-222, Standard CP1-prefix units).
Ford Transit(1 issue)
- PCM/ECM Software Calibration Causing Stall or No-Start After Refueling2015-2021
Ford Transit owners, particularly those with the 3.5L EcoBoost and 3.7L V6, have reported stalling or no-start conditions immediately after refueling due to fuel vapor purge system calibration issues within the PCM. The evaporative emission canister purge valve and PCM calibration can cause an overly rich condition when the purge valve opens after a full fill-up, flooding the intake and stalling the engine. Ford issued TSB 21-2299 addressing PCM reprogramming to correct the purge flow logic.

What does P0441 mean on Ford?▼
P0441 stands for "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.
