I am trying to test the IAT (Inlet Air Temperature Sensor) This is the one that sits under the inlet manifold, not the air box.

I have a reading of 12 Ohms with no heat applied (my workshop is at about 5 deg

When I apply a bit of heat with a hot air blower from a distance the ohms do go down quite a bit

What I dont know and cant find out is if 12 ohms is the correct value for it to be at at 5 deg ?

Can anyone point me in the direction of a book or something with bench test data so I know if this is correct

Its a 1995 p38 TD So I understand it is different from the 1996 on P38's

I will also be testing the MAP / Turbo boost sensor but I have no test data to compare it with

Thanks
