Really, I though that was a little circle shaped sensor in the block?
I need the little rubber boot that goes on the sensor pictured.

MAP sensor

edit: knock sensor is on the passenger side of the engine block, it also acts as the block coolant drain when unscrewed

The knock sensor is what screws into the passenger side of the block by the motor mount. The knock module is what goes into the PCM and tells the PCM how to handle the signals the knock sensor is giving. IE an LT4 knock module is less sensitive than the LT1 knock module, but the sensor (as far as I know) is the same.

I have a map sensor you can have which still has the rubber seal. You can have it I can have a door panel screw
