I have a knock sensor code showing up when I scan my car (99 LS1). According to the freeze frame data does anyone see anything that is out of the ordinary? I don't know what to look for to see a potential problem..any help would greatly be appreciated, thanks!

Freeze Frame Data when the code was thrown:


When I had it at idle:

 

Freeze frame data is useful for drivability related concerns. It will not help diagnose a knock sensor code, but can help diagnose knock. Regardless, in your case, you need to replace both knock sensors.

 

i just replaced mine knock sensor's today. turns out my oil pressure sensor was out too. i drove my car for a couple of months till i changed them. i took mine to a dealer. my hand held only showed knock's too.

 

I most likely broke during the intake manifold removal.
