Got code p0443 on 2000 jeep grand Cherokee Laredo 4.7 v8.

What is your question?

Replaced purge valve and still have code come right back after erasing code. Can't find much info except for checking entire evap system and just check all vacuum lines for cracks ripes ex. Ecm is possibility but that will be very last thing to check over hoping that I don't have to replace that! Any help would be dearly appreciated thank u and god bless!!
