Knock sensor location

[Force Fed]

Can someone tell me where it is? I have a '90 here at the house I'm working on, throwing Code 52. Is there a way to check it? It doesn't throw the light right away, usually appears after 2-10 mins of being started, even if it's just sitting and idling.

There are two knock sensors, both underneath your intake manifold.
