i am trying to help somebody with a p1445 code in another thread right now. look for obvious signs of damage to the evap tubes and other parts then get back to me.
As SVTtech suggests, check all the vacuum lines first to make sure they are all connected and there are no obstructions, cracks or sharp bends. If the code comes back you may need to change these:
1)Part# E6ZZ-9C915-A :It's the small plastic valve on a vacuum hose directly behind the TB against the firewall
2)Part# F57Z-14A606-BA: This is a metalic cylinder with a connector on one end and a T on the other. Make sure you put the vacuum line on the right side as flow direction does matter. This one is located under the AC Canister on the same line as the first valve.
Hope this helps. Takes like 5-10 min to do
