From: Central NYS
To run EVAP:
Engine off for minimum of 6 hours,
IAT between 40 and 100 degrees,
Fuel fill level between 30% and 80% of tank capacity.
(On certain year vehicles, NYS will allow OBD-II to pass
with one incomplete monitor. So to keep the EVAP monitor
from running in the summer, just keep the fuel level
below 1/4 tank until all the other monitors run,
and presto, no nasty EVAP codes to deal with at inspection time.) :-)

Wow
Pretty complex test procedure.
Weather must have just been warm enough long enough for it to run.
Checked again yesterday and it was showing completed
No check engine light.
No codes at all when scanned
REALLY appreciate all the help, advice, and info.
Know a lot more about the set up and test than before.
Glad I didn't just run out and buy a gas cap...
THANKS ! ! !
