What’s this sensor?

Hey. Quick easy one for ya all.

brough a vc commodore last week and cleaning up all the wiring. It’s currently running a factory water temp and after market water temp gauges with the sensor located front of manifold. It all has a oil pressure gauge which the sender for that’s near oil filter. Then there is a sensor ( pictured) located driver side and screws into the back of the head. 2 wires come off it then joint into one and goes into the wiring loom. What is this sensor for?

slight story behind car. It was a 6 manual with air con. Now is a v8
auto with no aircon but still has a bunch of wires it’s not using so just trying to clean up a bit.
Any help appreciated

Looks like one of the sensors that was used as part of the anti-pollution systems employed on the earlier cars.

Its a Temp Sender,
Possible for the Idle control,
As they had a solenoid on the Carby that held the idle a bit high when they were cold.
