The knock sensor is located on the back of the block just above the oil filter, and it requires a 27mm deep socket or wrench to remove it. As far as checking it I don't know. I have the same code and a buddy had a known good knock sensor laying around and gave it to me. I'm waiting for my next oil change to replace it because it looks like it will be a whole lot easier to change with the oil filter off. I believe to buy one they are over $100 so you have the right idea to test it first.

thanks for letting me know the location, but does anyone know how to test to see if it is bad or not?
