IAT AND MAP sensor are in same connector and unit has 5 pins and colored wires. What colors are the 2 wires that control the IAT sensor or what 2 pins work it, left to right, looking at face of connector? Lawrence Spillman
The tan and Light blue wiresmaremfor the IAT.

Hello, here is a picture of the connector and wiring.
MANIFOLD ABSOLUTE PRESSURE SENSOR (GAS) - BLACK 3 WAY
CAV
CIRCUIT
FUNCTION
1
K1 18VT/BR (3.3L/3.8L)
MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL
1
K1 18VT/BR (2.4L)
MAP SIGNAL
2
K900 18DB/DG
SENSOR GROUND

F855 18PK/YL
5 VOLT SUPPLY
Pink/Yellow is #3, Blue is #2, and Purple is #1. Your colors may appear slightly different

red with blue stripe and black... cut the red with blue strip and connect one end of the resistor to the harness side. Then splice the other end of the resistor to the black wire... do not cut it just splice into it.

A test light checking each connector would be faster and easier to do. Maybe somebody may have a illustration for you but by far a simple test light is all you need with a helper turning on the different lights as you check them out and writing all your findings down

Well im not sure why you are asking this question . They are two differant systems the mas air flow and the idle air intake bolth run off a 5 volt referance voltage but are not related so to speak to each other as far as the same ref voltage the same ground as every thing else .The IAT MAP TP ECT and fuel pressure sensor are one side and the MAF EGR and the EVAP are on the other side but all on a common ground . Ex plain what you are trying to do and why you are trying to do it and mabey i can make your life a little easyer and what caused this problem
