P0441 Code Evaporative Emission Control System Incorrect Purge Flow from www.carparts.com
Failure to develop a vacuum may be caused by a large leak or a restriction. The vehicle’s ecm will trigger this code when it detects that the vacuum level in the purge system is not within the proper specifications. The ecm commands the evap purge solenoid off once the system has reached a predetermined level of vacuum.
