There is a pressure regulator at the fuel rail (item 8 below). Not sure if that also controls the tank pressure.

I couldn't find any ftp in the pic below

 

Don't know about stage 1 but stage two it is on the firewall in front of the driver side. It is a switch in series with one of the tank lines.....

 

thanks for the replys just had time to get back on


theres a sensor on the same line as the evap pruge valve was told this is the ftp sensor , i swaped it and still getting the same code?

would yall think it could be a cloge in the line or hole, any chance the charcol canister could be pluged and giving me this problem?

thanks

 

Item 2 in the second pic is a two-way valve. I'm not sure how that might affect tank pressure. It might be stuck in one direction.

 

dk that's the one that the whole evap system starts from

thats a good one i have one extra from my old gas tank ill swap it and see what happens

 

I know right 2007 wants its thread back but did this ever work out for you
