S5 boost pressure sensor problem

So I seen this tread about the boost pressure sensor having a problem. Here is the thread.

https://www.rx7club.com/2nd-generati...adings-900082/

I wrote my response to the tread on what is the current status of this issue. "what is is the current status of this issue?? Cause my S5 turbo is doing the same thing.. can the grounding wire cause this issue of not reading proper voltage to the sensor? Or is it cause of something else that causes this low voltage?? Did ordering another sensor solved this issue?? Or did that new or used other sensor also put out the same voltage??" This is what is causing my engine code 13 to pop up on me. So any thoughts on this?? Cause only thing I can see is to order another sensor. But if doing that still does not fix the issue then could what I stated before in engine not being ground properly or something else causing this false reading issue??

Thanks

So today I received my new boost pressure sensor in the mail. this was after I did the test voltage (load test) on my old sensor. It only had 2 volts going to it. So I installed my new sensor and I reset my ECU by taking off the both the positive and negative leads to my battery and then held both the leads together for 15 seconds to drain all voltage in the whole system. I then put my leads back onto my battery. I started her up and now the code disappear on she is running fine with the new boost pressure sensor.
