Boost Sensor Error Code
 

I've been trying to get my car ready for the smog test in the last week or so, I just got my car back after being away for several months on a eurotrip and it had several error codes that I was able to get rid of, tps, and acv but my boost sensor code will not go away and the needle never moves on the gauge. Im woried because I think the ecu goes into a failsafe mode where it runs rich because it doesnt know how much its boosting. I've tried a couple s4 t2 sensors and one s5 n/a sensor but nothing and I don't know anyone locally with an s5 t2. How should I go about testing the wiring to the ecu from the sensor?

Dmm.
