P0441 is specifically Evaporative Emission Control System Incorrect Purge Flow. That means the engine control doesn't see the airflow it expects. It doesn't measure the airflow directly - it sees the change in engine operation that reflects the airflow when the valve opens.
Since you didn't get at P0443, 444, 445, ... faults, the valve probably has the right resistance. There are a bunch of faults that look for open circuits, short circuits, etc. So the wiring is probably just fine.
So the valve coil is probably fine, and it is possible the valve is just stuck. Or the hose isn't on right. I'd start with the hose.
