Completing the drive cycle

Hi, HELP! Code P0456. I have fixed the issue. Gone through the drive cycle. Three times. Driven the Jeep for 5 days. Over 200 miles. Yet I cannot pass emissions because the Jeep is not ready. What can I do???

You appear to have fixed it, stranger!

You did say that you'd fixed-it,right?

If you had not fixed it already but, you could look for :

Loose or damaged gas cap
Leaking or disconnected EVAP hose
Faulty purge valve
Faulty canister vent valve
Charcoal canister leak
Leaking fuel tank

Then you could intro yourself in Welcome Room thread so you no longer have to address folks who have never met you with ," HELP! I fixed it ...." comments ...
