They are notorious for wiring problems, could be that simple
But, it could be several things, the wastegate not functioning properly could tell the ecu that the boost sensor isn't responding, or it could just be a boost leak, etc
My suggestion would be to make sure no lines are leaking, and then make sure the wiring checks out
Not sure how inclined you are, but there are ways to test the actuators and diaphragms, if you have no idea wat I'm talking about, probably best to take it to someone
Finding a bad wire and fixing it can be a real bitch. As a mechanic id rather have a bad sensor over searching for that tiny piece of wire that is bad
