I have been looking for any and all info on this code...and I really can't find anything on it...

P0452 - Evaporative Emission Control System pressure sensor low input

Now I have bought a new fuel cap and replaced the fuel tank pressure sensor( not cheap ) I've been under my car and can't seem to find really anything broken, disconnected or bad.

I am very well versed in fixxing cars, but I cannot figure this one out...any help would be greatly appreicated.
