bpt valve egr code 32

[godspeed]

ok so here is the deal, i have a check engine code 32, i took off the vacume hose to the egr valve to see if there was vacum and there is none, so i pulled the bpt valve and checked the hose under it( it does like a T) and there was on that, but none on eaither side of the bpt valve, so i took a vacum t thing and just took out the bpt valve, and cleared the code and well the damn thing came back, but what is weird is that after i clear the code i start the engine up and when i put my foot on the gas the light will come on and as soon as i release it it goes off, then after i turn it off and back on it just stays on the whole time, this happened with the bpt valve on and with it off and just t-ing all the lines toghether, does anyone know what to do?

do you have a header? also, vacuum isnt generated until about 3000 rpms with a load.
