u can forget the purge valve. 449 CAN be either the vent valve itself OR it's control wiring. but more often than not, replacing the vent valve solves it.

My question was really to confirm the location and part number of the vent solenoid.

it's above the fuel tank which u need to drop down on the right side for access (some claim that dropping the tank isn't needed-u decide). i cant help u with part #. i'd imagine there's a how-to by someone on youtube. or u can post an email addy & i'll send a how-to this time. tell that car owner factory service manuals are worth their weight in gold.

if u want to confirm a bad solenoid just put 12v across it & listen. also, a bad solenoid will usually have infinite resistance.
