DTC P1457. What is the best way to troubleshoot the Evap Canister components? I Have a Fog machine, and have Multimeter. Can you provide any electrical/ resistance specifications?

You need to smoke the system for leaks. You need to check resistance of the purge, flow and vent solenoids. Should be around 6-8 ohms. Any lower, they are no good as may be the computer.

Lastly, you need a scan tool to tuen the solenoids on and off to verify the pcm can do this job
