Hi,folks,I am new to the site.I had my check engine light to come on,so I took it to the local auto parts store and they put an obd 11 scanner on it and the codes 450 and 441 come up.They told me that it could be several things such as the pressure sensor switch malfunction or incorrect purge flow/IT'S funny ,because they won't sure where they are. Can you guys help me on this/Maybe a diagram/

 

Use the FSM (Factory Service Manual) link in my sig to get a manual close to your rig. And, start searching this site.
