Evap codes question

hey guys, I have an 03 V6 and recently got p0446 p0442 and p0441. I’ve tried the gas cap, didn’t work, I seem to get all the codes back after the drive cycle completes. I’ve checked the vacuum switching valve on the drivers side of the motor and it is clicking open and closed and seals fine. I noticed what appears to be another VSV on the back of the intake with two smaller lines going into it. For shits, I checked that one with power to see if I could hear it clicking open and closed, and I could not. Should this be opening and closing and making noise? Is it part of the evap system? I can’t find a part diagram for it anywhere, here is a picture of what it looks like;

 

here is a parts diagram showing that valve, looks like it has a line going to the EGR valve?

 

Anyone else with a 4th gen get p0441 p0442 and p0446?

 

No, but I would make sure to check your coolant and oil to be sure. Head gasket issues are prone to the earlier model 4.0 V6 engines.
