vid one depending where you have that gauge hooked into should show a vac at least 25hg on idle to the inport to the Tcv from the out port of the TCV you should have at idle 25hg pads on, above 1500 rpm no vac to out port of Tcv pads off.if there is a pad leak it can effect the vanes on the turbo and cause that code
