2012 Husqvarna Te 449 Secondary Tps Setup

I recently purchased a 2012 Husqvarna TE 449, it seems to run fine however the display shows the fail message on the speedo display. After reading a number of posts on this forum, I ordered the cable and OBD adapter so that I could use the TuneECU software to read the error code. Once I got things connected, I was able to get the code which indicated a short to positive on the secondary TPS sensor. I went ahead and ordered a new TPS sensor thinking this would be it! I replaced the sensor only to see the dreaded fail message again on the display. I cleared the codes using TuneECU and also tried disconnecting battery for a few hours to reset ECU. TuneECU shows a consistent 4.85 volts on the secondary sensor no matter what position the throttle is in. I did take a flat blade screwdriver and turned the tps sensor with TuneECU monitoring the TPS voltage and the voltage does vary when I turned it. My question is what is the correct procedure to install the secondary TPS and what voltage range should it display at closed and full throttle? side note the secondary butterfly has already been removed by previous owner.
