Outside Air Temp Sensor failure?

[Rex Kerr]

My '05 Outback is constantly displaying 73 degrees as the outside air
temperature, no matter how HOT or cool it actually is.

Is the IAT (intake air temperature) sensor the same one that is used to
display the outside air temperature? If so, I'm guessing that it was
probably messed up during my 30k service and should be covered under
the longer emissions warranty. If not, where is the outside temp
sensor located?

Thanks!

No it's a separate sensor. I believe it is located up front ahead of
the radiator. This doesn't sound like the sensor is NG however, if it
were disconnected the temp would read very low and if it were shorted
the temp would read very high In any case if this only happened since
you had it serviced just take it back and make them fix it.
FYI the emission warranty to 8/80 only covers the catalytic
converter(s) and ECU, not the sensors and other components.
