Knock Sensor questions

I have a check engine light, so I did a diagnostic and I got code 52 for knock sensors. One knock sensor (front sens.) was broken so I went to a junk yard and pulled one off another toyota (dont remeber what car). It fit fine, I just had to rewire it. But im still getting code 52, the check engine light is almost always on, even when the car is at idle. Ive also noticed that at full throttle the car dosent pick up after 80-90mph like before, it slows down alittle.
