Location of Internal Temp Sensor??

Hi,



As some of you already know, I'm working on the MG-UI car computer which uses OBD2 to read data.



I tested it today with some random PID's from the OBD2 port, one of them is internal temperature.



Didn't expect it to work, but it is returning an in-car temp reading from somewhere.



My car is in the sun at the moment, and had a reading of 32, which dropped to 30 when the doors were left open for a few minutes, so I'm sure it's getting a reading from somewhere in the cab.



My question is... does any one know where this sensor actually is?
