So, I got a Scion with a problem... Help?
Yesterday i took my grandmother's Scion Xb to put gas in it. I noticed the CEL was on, so I scanned the codes:
PO441 Evap purge flow fault
PO442 Evap system leak (small)
PO446 Evap vent circuit malfunction
Basically i am at a loss. I have researched online but can't come up with and definitive answers. The warranty expired 2,000 miles ago and i am not wanting to take it to the dealership.
I have checked for vacuum leaks, gas cap for tightness, and cleared the codes. The light comes back on after about 5 or 6 miles.
Does anyone have any ideas? I am really hoping that it is not the vapor canister. I would really appreciate all the help i can get.
