Hello and thanks for donating
Sensors are not made to last the lifetime of vehicle, especially oxygen sensors. O2 sensors should actually be replaced on a regular basis just like any other routine maintenance part (i.E. Filters). The knock sensor failing at 118k miles isn't really bad, thats a lot of miles for one sensor to endure. 118k miles is also a lot for plugs, I would suggest replacing those soon as well.
