It took one week last time for evap monitor to be set (after battery replacement).
This time (after cleaning the battery terminals and idle re-learn) the evap still not ready after 3 fill-ups. The good thing, I don't need a smog until next year so I will discover how many months it will take for monitor to be set.
Thankfully, my next car will be either the electric one or a smog exempt small vintage car like shown https://www.netcarshow.com/Fiat-124_...-wallpaper.jpg

 

Keep at it. Make sure it's on battery the whole time. It will decide when it's time. Good luck finding that Fiat, although you could easily get the '15 Fiat 124

 

Update.
Last week I reset the monitors with Innova scanner, filled up the tank and drove normally until next fill -up (yesterday) Today the evap monitor is finally ready.(1 week from re-set or the second fill-up cycle)
The reason it was not ready last time almost 4 weeks was that I tested purge valve for leaks (which required disconnecting of the fuel vapor hose) The disconnected hose (for 10 minutes) confused the fuel tank leak sensor and delayed calibration of it!
Another lesson is learned!!

 

First post here, just purchased a 147,000 high mileage Fit this weekend. 2007. Everything seems to be alright with her except I'm getting the same EVAP error (actually brought my car to AAMCO to do a full inspection, just in case).

My case might be a little bit different. Turns out that when I bought the car, I knew it had a burn mark on the front bumper. I wasn't too worried about that because replacing the front bumper is relatively cheap and when it comes to painting, im considering Plasti-dip the whole thing. Anyway, AAMCO determined that the burn on the front bumper came from a bad jumper-cable related fuck up from the previous owner. Either they left the cables on for too long, or something caught fire when they had it connected. I've never seen anything like it.

Anyway, the short of it is that its spitting EVAP error code right now and I can definitely tell that the battery is brand new. My question here is, this is common? Also, can I do my own code testing at home? If so, what to get for the code test?

Thanks
