check engine light came on - possibilities

[TK1975]

99 Toyota Corolla. My check engine light came on while I was driving. Stopped at Advanced Auto to code and 2 came back,

PO441 EVAP Emission, Control System - Purge Flow Fault
PO446 EVAP Emission, Control System - Vent Circuit Malf

Anyone have experience with this code ? Is it dangerous to drive now ?


Thanks

I am not a pro by any mean - nor do I feel worthy to be in a room with these pros. But I do want to help.

The advanced search from this forum, specific to 8th gen Corolla and ranked by the number of replies, yielded the following results. I read all searched threads to filter which threads had better guidance than the others.

I did this because,
1) it is a common issue,
2) wanted to fatten my brain with "preventive knowledge" for "preventive maintenance",
3) it is fun until I get the CEL.

Yes, factory service manual, available on eBay for about $100.
