I have some check engine light codes that just popped up; PO325 knock sensor malfunction, and PO113 IAT intake air temp sensor. I know where the IAT is, and what both parts look like by checking on ROCKAUTO, but I'm not sure where the knock sensor is located. Can anyone point me in the general direction?

 

Also, I find it curious that both of these went "bad" at the same time. I had to pull my right font drive axle last week and unplugged a couple of wire harnesses to get better access. I didn't disconnect the battery first, and wonder if the unplugging and plugging might have fried them. I re-checked the connections and everything is together. Just curious if anyone has any thoughts about it. Thanks.

Knock sensor is under...ish the intake manifold on the drives side, easy fix. 12mm socket,wobbly,extension. Be sure not to man handle the new one down,as you may crack it, just tight enough so it stays in place.
