It is behind the cover inside the right rear wheel arch mounted on the EVAP canister. To get to it you remove the right rear tire, then pull the push retainers and bolts that hold the liner in place. With it out you will see the pipe that runs from the fuel tank to the EVAP canister. Disconnect it and the vent line and the electrical connector. Then release the tab and you can lower the EVAP can enough to get to the release clips on the solenoid. Replace it and reverse the process to put it back together.

I didn't find it under the right wheel arch. I will check under the other side when I have more time. Thank you. I'll try it out today.
