Code P0441 2012 Nissan Sentra Description

The P0441 code on a 2012 Nissan Sentra indicates a problem with the vehicle's Evaporative Emission Control System (EVAP). Specifically, it points to an incorrect purge flow in the system. The EVAP system is designed to capture and store fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. The system then purges these stored vapors into the engine to be burned off as part of the combustion process.
