A noob and his vapor pressure sensor

I'm new here. Cruised the various threads and the long and short is I have been wrestling with my taco's evap system for almost a month. I have cleaned and checked two valves in the engine compartment, blown my evap lines clear, replaced the canister, smoke tested for leaks and finally found out that my fuel vapor pressure sensor has been "stuck" at a reading of .02 psi regardless of engine rpm speed.
Has anyone else ever had to change out their fuel vapor pressure sensor? If so did you need a new gasket and how much of a pita was it?

My truck is a 2002 tacoma, extracab, 2.4 liter 4 cyl, 2 wd.
Any assistance would be appreciated, thanks.

 

Wish I could help man!
