quick question about checking CEL's
Ok, I just took out my bad IAT sensor off my intake manifold and put a new one in cause I was getting a checking engine light for it (10). Then I pulled the ECU fuse and backup fuse and let the car sit for about half an hour. I then put the fuses back in and started the car up without touching the throttle and let it run for a few minutes. So how can it be that I am still getting a check engine light for the intake air temp sensor? When the CEL starts flashing is there a flash just to show you that it is working or does it just start with the codes right away?

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.

What I don't get is that after taking out the old IAT sensor, part of the long part that goes into the intake manifold looked melted...That's why I really figured the IAT sensor was the culprit...
