Vapor Canister Purge Solenoid

Can someone tell me what this does and how it works? Why is one end connected to the TB and the other to a box near the radiator?

The vapor canister captures evaporated fuel from the tank(s) and the purge valve allows the engine computer to control when those fuel vapors are allowed to be drawn into the engine to be burned.

This sounds like it's to avoid venting those vapors into the air to reduce pollution, is that the case? I can't see these vapors, which are diluted with air before being used, as a source of power.

Yes, that's why they classify the CANP (Canister Purge) solenoid and vapor canister as part of the Evaporative Emission system.

It's strictly emission control.
