You were right Tracy, s= omething was not right. My helpers ignored P2-21 pin. After couple of hours = ringing all the wires and not finding #21 I opened the connector and pin #21= was empty. Now is all fixed and the temperatures show right.

Something is not right.  Make sure you connected the sensor return lin= e to the OAT bias line instead of ground like the other air temp sensors. &n= bsp; OAT is different because I wanted it to be able to read down to at= least -40 degrees F.  It is not calibrated in C although it should be = possible to do that if you wanted.  
 
After double checking all wire connections to it, let me know what you see.=  The unit is tested with a bench reference sensor on the OAT function = so I'm fairly certain that the unit is working but it is remotely possible t= hat the sensor is bad.

Hi Tracy, I connected OAT sensor today, but the display shows  single = digit
number 5-6. When I blew some hot air with the hair dryer on  the senso= r, the
numbers climbed to 11 and than settled to 5 after removing  the heat? = I
wander if the reading is in  Celsius?
