P0441 code is triggered when the computer of your vehicle's engine detects an issue related to the purge flow of the Evaporative (EVAP) Emission Control System.
As far as trouble codes go, the P0441 code isn't particularly common. It's a minor risk code that often shows up on Chryslers that other vehicles.
The specific reason behind the issue can differ from one model to the other, so you'll need to do some testing to pinpoint the defective component. Continue reading to find out more about the code P0441.
The P0441 code is Evaporative Emission Control System Incorrect Purge Flow. It's a diagnostic trouble code (DTC) which is a generic OBD2 powertrain code.
This means the code P0441 applies to all vehicles manufactured since 1996. But still, some models will require additional or distinct steps for repairing.
The code P0441 is triggered by the engine computer (ECU) when there's an incorrect purge flow detected in the Evaporative (EVAP) Emission Control System.
The Evaporative (EVAP) Emission Control System is one of the solutions by which your engine reduces its harmful emissions. This system prevents the escape of dangerous, smog-producing compounds in gasoline vapors from the fuel tank into the atmosphere.
The EVAP system catches these vapors and stores them in a charcoal canister which contains small pellets made of activated charcoal. The pellets are responsible for absorbing pollutants to "clean" the emissions.
When the engine is running, the purge volume control valve allows fuel vapors to move from the EVAP system (the charcoal canister) and into the engine where it's used in the air-fuel mixture required for combustion within the cylinders.
The engine computer module (ECM) controls the amount of vapor purge flow via gradual opening and closing of the purge valve. The EVAP system pressure sensor, along with other sensors, is responsible for monitoring the exact amount of purge flow.
If these sensors pick up an amount of purge flow that's different from what it should be, the ECM determines an error and triggers the code P0441: Evaporative Emission Control System Incorrect Purge Flow.
For example, the system isn't properly purging so the amount of purge flow is lower than what's expected.

The issues caused by the P0441 code don't affect the drivability of the vehicle. However, there are a few mild symptoms that you can notice:

The P0441 code isn't something serious and it doesn't indicate a risk of danger. The driver is very unlikely to notice any change associated with the P0440 code other than the check engine light going off.
That being said, it's best that you resolve the issue as soon as possible, just like any other check light engine DTC.
