P1441 Undesired intake manifold vacuum flow to the EVAP system
Yes this code can be set by either of the two component the Purge solenoid or the FTP (Fuel Tank Pressure ) sensor, the fuel tank pressure sensor is located on the fuel pump, it more easier to test the purge solenoid, by looking into the scan tool long trim and short trim, if the fuel short and long is greater than 10 % you have a purge solenoid stuck open, or you can remove it if you can blow through it its faulty.
