P0446- Evaporative emissions vent system performance (may be a evap purge solenoid)
P1441- Evaporative emissions system vacuum is greater than predetermined value (possibly same solenoid)
P1639- 5 volt reference 2 circuit. (Has to do with the A/C system and the PCM monitoring and controlling it.)
The last one will probably be the most time consuming to fix. The first two codes are possibly related to the same problem
