HelloCustomer P1441 means EVAP System Flow During Non-Purge Conditions.This deals with the purge solenoid, vent solenoid, charcoal canister, all the vacuum lines in this system, as well as the gas cap. Any one of these components may contribute to this code being set. All the wiring should be tested including the connectors for any problems. Vacuum lines should be checked for cracks or loose connections. The canister may be damaged or not working properly.
However, the most common cause of this code on nissans is the evap vent control valve. It is located on the evap canister, under the rear of the car by the gas tank. Its the only electrical device attached to the canister itself.
If the code was because of a vacuum leak, then yes.
