Could someone explain where the IAT2 sensor is or take a pic. Have two codes P0098 IAT Temp Sensor 2 circuit high voltage. P0480 Cooling fan relay 1 Control Circuit PCM/ECM.

 

Those are weird codes. Try unplugging the PCM for about a minute and then re-plugging it back in. If they still come up as codes, then you might want to look into it more.

 

When looking at the motor under the hood, the IAT2 sensor is on the top left (passenger side) corner of the intake manifold. It is also the MAP sensor.

Did you do anything recently that may have caused the codes? What happened or what were you doing when the CEL came on?

 

I found the problem......connector was not tight. Snapped into place and everything is ok.

 

all else fails. wiggle it.
