Ambient temp sensor reading -40F after replacing sensor

My 04 C4S was missing the external air temp sensor in the front bumper when I bought it. I ordered a new one and installed it, but the readout on the dashboard says -40F, even though it is 70F here today.

 

I get no related errors in Durametric (although it is crashing every time it tries clear faults in the AC module.)

 

Any ideas on recalibrating this unit?

I'm not sure the Durametric can help you with this, it may require a PIWIS.
