Dont' change the knock sensor until you've fixed the o2 sensor code, and the knock sensor code is coming up all alone.
The knock sensor code won't trip the CEL. So after the o2 sensor is fixed and reset the ECU, pull the codes a couple of weeks later and see if the ks code is there. THEN you have reason to change the knock sensor.
