Whats this sensor??

Its located on the right side of the motor right behind the exhaust manifold. Its got a connector and the sensor is screwed into the motor. Is this the knock sensor or something else?

Yeah. One other thing too, I noticed my fan doesn't seem to be kicking on automatically, I have to turn the a/c or heater on for it to kick on. What could this be? I got home last night and noticed it was a hair over 240 degree's. When I just turn the key to on, the fan should be on shouldn't it? Especially when its that hot..?

Knock sensor and fan switch use the same type of connector

Knock is lower in the actual block while the fan switch is in the cyl head
