Full Answer

Code P0441 is a standard code under the on-board diagnostic parameter ID (OBD-II PID) system, a diagnostic reporting system required in most passenger vehicles sold in the U.S. since 1996. When a vehicle's on-board computer identifies a problem, it logs the appropriate OBD-II PID code and illuminates the check engine light. To retrieve this code, an automotive technician connects a scanning device to the vehicles OBD-II connector.

The evaporative emission control system collects fuel vapors from a vehicle's fuel system. When the engine is running, the collected fuel vapors are purged into the engine to be burned rather than released into the atmosphere.
