After replacing the canister purge valve and two downstream oxygen sensor, the check engine light is still on, and the same group of codes displayed. When turning check engine light off it comes on again after turning vehicle off, and back on.

Now you want to diagnose the code to find what the problem really is, why didn't you do that before replacing the parts. There are not really very many places in one town that have the people and equipment to actually fix EVAP codes. Try Find a Shop for your zip code.
Thank you. I really appreciate your answer.
