P1441 Means the system has detected flow thru the valve when there should not be any. As saywhen said, it could be some doo-doo stuck in the valve, or there may be a leak in one of the vacuum lines. Crossing the vac lines can also set this code. The PCM thinks the EVAP switch is ON, when it should be off, which could mean the valve itself is open, or the switch is stuck.
Check the connectors on the valve....may just be loose, or the wiring may be deteriorated. If the wiring/connector is good, then check the valve to see if it is actually stuck open with doo-doo.
