99 pathfinder and the engine light came on on 1999 Nissan Pathfinder

when checked the codes were: p0325, p0120, p0731, and p1705. The throttle position sensor was replaced, but now it sticks a little when shifting from first to second gear. Do I need the knock sensor replaced?
How much should this cost
