SES code help plz

Ok i got a SES code pop up today. I went and scanned it and got the code po441. Evaporitive Emissions Control system incorrect purge flow. Now my question is is it the EGR valve or something else? Also whats does a EGR valve costs these days?

Has nothing to do with the EGR system. It is the "EEC" system... the vapor collection canister in the drivers rear fender, and the purge system on the passenger side of the intake manifold.

P0441 specifically is "no flow during purge". That means when the PCM told the EEC purge solenoid to open, it did not detect flow in the sensor between the purge solenoid and the throttle body connection. Plugged lines from canister to solenoid, plugged or defective solenoid, or plugged line from the solenoid.

O thank god i didn't want to have to replace the EGR valve. Looked like a ***** and a half to do. So do I just have to replace the clogged line and replace it? Thank you much man for the answer to my question.
