Hey guys, were the hell is the IAT sensor on the mazda 3. I know it is near the intake hose, but there are two connections by the intake housing that i need to locate. Does anyone have a pic of the engine that they can just point an arrow to the IAT sensor? thanx guys

For a protege, it this:
It's the 2 wired plug thing coming out of the upper right side of the airbox. NOT the 3 wired rectangle on the intake tube between the air box and throttle body.

dunno if its the same for mazda3 :)

might help, might not

no, i have on plug thing with 3 wires and another with 5

ahh.. oh well, i tried :)

IAT sensor is part of the MAF

For a 2.0L Protege


NOT a 1.6L...We have the IAT incorporated into the MAF

1.6L MAF and any Mazda3 MAF are interchangeable parts

learn something new everyday.

i still havent had my question answered, why the hell don't i have a wire harness coming out of the IAT sensor with only tire wires coming out of it. I need this bc im putting in a resistor wire for air temp

Yes you have...the IAT sensor is incorporated into the MAF... :rolleyes: the "5 wire thingie"..

btw IAT modding with a resistor is fucking useless....excuse my french.....you WONT get any horsepower out of it....

damn o well, well i could still try, what wires am i supposed to use if i decide to try it
