Hi all, Thanks so much for getting back to me.
So, yes its a turbo, and after i did a little more research learned that this model year 03' apparently only has one sensor on the intake from the intercooler to the throttle body. Finally got ahold of our family volvo mechanic and he said the earlier years, like 98 -02?? had two sensors, the MAP and the Boost Pressure sensor. He was pretty confident that my year only had the BPS with the IAT sensor built into it. So after work I'll try cleaning it and checking the wires, since that was easy enough to find, (by the drivers side headlight in the intake tube right next to the intercooler.) I'll try to post some pics later tomorrow or this weekend and I'll mark the post as solved if I get it working.
Thanks again!
