99 323i throttle body replacement

So my mother owns a 1999 BMW 323i, with the m52tu motor, and the throttle body needs to be replaced, she does not know much about cars and does not want to take it in to a mechanic, I know how to replace the part but I just need suggestions on where to get a new throttle body (the code the motor threw says the throttle position sensor is defective, and the m52 in the e36 of the same year has a separate throttle body position sensor, but the e46 with the m52tu has an integrated throttle position sensor in the throttle body)

I did a search for sensor on RealOEm and didn't find a throttle position sensor:
I just had my throttle body off and don't remember a sensor with wiring. Can you post a picture?
