Just ran my codes and I guess my knock sensor is dead as well as both the front left "02 sensor heater" and the front right 02 sensor "heater".

What is an 02 sensor heater, and how do I replace it?

Anyways, I read that in order to replace the knock sensor, you must drain the coolant? Does this sound right?

Thanks.
