Canister Purge Solenoid. Behind right headlight.

Canister Purge (CANP) Solenoid Valve
Normally closed solenoid valve controls the flow of fuel vapors from canister to intake manifold. When engine is shut off, vapors from fuel tank flow into canister. After engine is started, solenoid valve is energized and opened, purging fuel vapors into engine.
Canister Purge (CANP) Valve
CANP valve is a part solenoid, part valve component that is used by the PCM to regulate flow of fuel vapors from fuel evaporation canister to fuel system. The CANP valve regulates the flow by means of manifold vacuum and duty cycle signal from PCM, which regulates the CANP solenoid valve.

Awesome - thanks. Let me chew on that for awhile. Any specific electrical connections that normally cause this fault, or is it usually the canister needs replaced in your experience?

After rereading your post - I think you are saying the solenoid hangs up. Can I clean it or just replace it?

Dave - ever looked at one of those? I can't even get my hands on it. It is almost impossible to get at. What do you do? Take off the air dam on the bottom and come up from underneath?
