The Van just came back from a long trip (approx. 2000 mi) and a week after ariving home, the check engine light came on. I was able to retrieve the codes: P0466, p1441, and p1639. I have tried searching online and it seems to point to the evap system, and maybe a tranny code. I would like an idea of what would it be before I take it in to be checked out or repaired. Thanks.

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
