How do I replace the evaporative emission system sensor in a Nissan Sentra?

I have a new-to-me 1999 Nissan Sentra which failed its emissions test with the error P0450 (Evaporative Emission Control System Pres-
sure Sensor Malfunction). I want to replace the sensor, but I have no idea where in the car it actually lives or what it looks like.

I have an ODB-II reader, so I will be able to tell when I do get it fixed, but first, I am looking for a place to start. Suggestions on how much the part will cost or whether it will just be easier to take it in and get it fixed professionally are welcome.

I think another name for this part is 'fuel vapor canister', and, it sells over the counter here (Kelowna, BC) at an aftermarket store for just over $300, Canadian. It doesn't look that common, however, so you may be going to the Nissan dealer.

I'm not sure where it is, but I can email you a picture of it if you want.
