I recently ordered a Intake Sensor Mod, but I'm not quite sure where the intake air temperature sensor is in a 1996 Ford Ranger 2.3L. Can anybody help?
Welcome to FTE ltabora.
The IAT sensor on the 2.3 is on the air duct that attaches to the throttle body. The sensor is about 6" away from the throttle body on the side of the air duct.

It Aint Fun Unless It's Done The Hard Way!
I got one of those sensor mods and it made my 95 run like crap,so after some checking i found that since its only a resistor,Imeasured it and it was Too low of a resistor.acording to the book, you want a higher resistance value to make your computor think its colder out than it really is,thus it advances the timing through the CPU.Iwent to radio-shack and got one,69K ohms.it worked alot better.
You just unplug the sensor and fold the resistor wires over about half way and plug it into the wire plug that you unpluged from the sensor,it does'nt matter which way you plug it in.The inprovement is only slightly noticable.Like going up hill,say your truck downshifted at halfway up the hill,with the resistor it may go another 50-75 yards before downshifting.
Slight power increase(10 HP)But you seem to get a smoother idle,Because the resistor tells the PCM that its alot colder out than it really is,so the PCM advances the timing a degree or two.
By the way,check the resistor with a multi-meter.you want AT LEAST 69,000ohms,any less will not give a performance increase.The book says-the IAT is a thermal resistor that changes value at different temps.For example,at 68 degrees F the resistance is 27,000 ohms , at 160 degrees F it is 7,000 ohms.You might even experiment with higher resistance for better results. I went with 69,000 because I just wanted to compensate for running the A/C. P.S. resistors come in odd sizes,33,47, 56 etc. But they are only $2. at radio shack.
Instead of working to get the perfect resistance for your IAT (intake air temperature) sensor in different conditions you could try a variable one. I think these guys have something like a POT to adjust your IAT.
