I need help locating the IAT or Intake Air Temp sensor. I seem to not find it and there are too many plugs to tell from. I dont want to unplug the wrong thing. Plz reply

Yeah, the IAT sensor wire is actually integrated with the MAF. The MAF is a 5-wire plug that plugs into an outlet on top of the air intake box. Look for the blue wire with a black stripe, that is the IAT. That is for the 2005 model though, not sure if 2003 and 2005 will be the same color wire...

If you are looking for the sensor itself and not jus the wire, well, the sensor itself is inside the box. I'm not sure how to get at it because of the screen that goes in front of the filter. Maybe you have to take the hose off, I really do not know, sorry.
