Can anyone tell me the location of the IAT sensor on my 07 Fit, or if anyone has a diagram or picture to help?

 

Look directly at your throttle body, then look to the right about 4". The IAT is the sensor that is plugged into the back side of the air intake, between the plastic intake and the firewall. It is mounted to the intake with a rubber gasket ring. If you hold it tightly, you can wiggle and flex it in the rubber mount.

 

Are you puting in a new intake? if so you may need to take out that rubber grommit(sp?) out of the OE Intake tube.
