Post subject:  2002-2003 IAT sensor

Ok guys found out something very cool. I have an 03 and my brother has an 04. Remember how they changed the intake for 04? well they moved the IAT sensor to near the intake pipe. The iat sensor on the 02 and 03s is on the intake maniford. With my scanguage the air was coming in at around 110 degrees and my brothers was around 80 degrees. So that how i found out about the sensor relocated. Well i remember a trick where you put a resistor on the sensor plug and trick the computer into thinking the air was colder. well i just wanted the computer to think what it was suposed to think. so i bought a few different resistors at Radio Shack and tested a few out and found out that a 1/2 watt 10k ohm resistor made the computer think that it was 76 degrees out. No engine lights by the way. All in all i think everyone should do this if you have an 02 or 03. that is why they moved it. I did notice a bit of power. IF you go to high of a resistor the computer will adjust timing too much and you will have detonation and throw a code.
Just thought i would let everybody know.
