P0449 Condition for computer test (i read the sticky)
truck is a 2010 silverado 5.3
i would like to know the exact conditions to trigger the computer to run this test for p0449 code.

i have 2 days to replace this part and clear the code or it will interfere with the wifes vacation (and the rest of my happiness). i have the silinoid going in tonight, need to get the truck to test and clear the CEL so my emissions will pass.

i once found the exact conditions to trigger evap testing on my ford, but cannot find online for this truck.

thank you in advance!
