P0441 Evaporative Emission Control System Incorrect Purge Flow Low
The P0441 code means the computer commanded the vapors stored in the canister to be purged into the engine and did not see the expected effect: either no vapor flowed, or it flowed when it should not have. The most common cause is the purge valve, whether it is stuck, has an electrical control fault or the hose connected to it is clogged.
