There's two diagnostic trouble codes for (10).

P0112- Intake Air Temperature Circuit Low Input
P0113- Intake Air Temperature Circuit High Input

Though you know the malfunction code, it's possible you don't know the diagnostic code.

Probable causes:
P0112- Short in IAT sensor circuit/ECU
P0113- Open in IAT sensor circuit/ECU

Honda has a PGM tester for this type of malfunction. I doubt you will be able to troubleshoot this one on your own without the proper scan tool. Their could be a voltage problem at the ECU wire terminals. It sounds to me like you assumed the problem to be the IAT sensor. There's various probable causes for CELs.
