Do I have 2 OAT probes? (photo)

Does the aircraft have two AHRS, or two EFIS screens?  The OAT input may be duplicated along with those other redundancies.

I have both a PFD and MFD, but it would be news to me if I had redundant AHRS systems.

Trace the wires, where do they go?

That’s highly impractical and would take hours of tearing the plane apart.

If you have a Garmin GTX 335 Mode S Transponder this second sensor could be for it to display static OAT.
