How exactly do you do a TBA, i tried leaving the key in the ON position for like 10 mins and nothing happened. What is the exact proceedure?

 

I got the 0411 code and it was an issue with the purge valve on the vac hose that comes from the gas tank. apparently its an inexpensive fix if you do it yourself. In my case the valve was just frozen, so when it warmed up and I reset the CEL it was and has been fine ever since.
