It measures the pressure in the intake along with the temperature. On the Turbo cars it reads the gain in boost pressure for the engine controller.

I've spent a ton of time searching on Google and other places but I'm coming up with nothing useful. Bosch's website doesn't have any useful information either.

It looks like this;

What's the max BAR/PSI on a stock 1.9 JTD? I couldn't find that online either.
The 2005-2006 Jeep Liberty CRD uses the Bosch "TMAP" sensor as you refer to it. You can get it at http://www.showmeparts.com in the US. The CRD is a turbo diesel. One of these I believe are what you seek. The part # is not given but if you talk to the parts guy give him the Bosch number, it is on the Mopar part as well, and he can verify which is correct. It controls somewhat the egr function on the CRD.
