I assume this is a chip from eBay. I suggest not going that route. All those "chips" are, are resistors that trick the car into thinking the air temperature is a certain degree, which can improve performance. However, it can affect other aspects of the car and it could cause long term damage. Also, modifying car wiring on a critical part like the IAT could cost lots if it is damaged.

SOURCE: installing chip and want to double check wiring. Need to find IAT/MAF sensor diagram for 2003 Ford Ranger

Save your money, the chip is a ohm resistor at Radio Shack for under $2.00. It splices in to you IAT wire harness located at the intake tube between the air filter housing and throttle body.
Problem with this system is, that you can not adjust anything and have to run a constant 91 octane just to make sure you do not have a Detonation. The ECM will catch the Detonation from the knock sensor and compensate for it by retarding the timing which in turn lose of HP till next start up.
If you like and don't mind the check engine light on once and awhile, you can do the same by just disconnecting the IAT wire harness which give the ECM a 0 resistance thinking it's -20 out side and turn the timing up and lengths the injector pules.
When i was running a Nitro in the Toy before i sold it, i had installed a 10K ohm Potentiometer which you can buy at radio shack for under $5.00 i believe, I just spliced it in to the IAC wire harness so if i wanted to play with the Nitro I'ld turn the resistor up making the engine think it's 185 degrees F and would ****** the timing so i would not hurt the engine. But if i wanted to get more timing i would just turn the knob to drop the resistance to get more time since the engine thinks it's -20 out side.
Hope this helps. Keep me posted if you need more info. Best thing is to do a dyno tune and you can change everything right down to the Shift points.

SOURCE: There are 5 wires in

The air temp sensor, removing it or unplugging it MAY do a few things depending on the type of sensor it is. Most send a signal to the computer in terms of resistance (ohms) that changes with temp. That signal is used by the PCM in conjunction with others (MAF O2s MAP) to determine timing and fuel requirements. If you unplug the IAT sensor the computer (on most GM cars) will see an open or infinite resistance and give the lowest possible temp input to the computer for air temp. That can increase timing across the RPM range sometimes giving a few extra ponies. It can also lead to detonation if too much timing is present. 

I hooked up a 10k ohm potentiometer to my IAT sensor so I can dial in the temp I want. If I want some timing ****** for nitrous I dial it so the computer sees 185 degrees F and it takes 2 or 3 degrees total timing out. For more timing I Dial in 20 degrees F and it will advance it some. Works good. 

The 10K ohm you can pick up a radio shack for under $7.00 and wire fo $3.00. You can connect the chip you speak of to the pink wire from the IAT sensor which is not a part of the MAF sensor. The IAT is along the intake tube between the MAF and Throttle body with two wires from it.
The chip you bought is the biggest rip off and i wish i though of it but, well about marketing it. Your kinda stuck running 91 octane and changing the thermostat to a lower rating. The first engine knock that the knock sensor picks up will turn the timing down and shorten the fuel injection pules, That's why i played with the potentiometer and every other cars i get to play with around town.
Good luck and hope this helps. Keep in touch oh and if the knock sensor picks up the detonation, you lose around 10 to 15 HP. Till the next start up.

SOURCE: cant find IAT on 99 jeep grand cherokee laredo...

Intake Air Temperature sensor.

It has to be installed ->BEFORE the throttle body, to sense the density of the air entering the intake manifold, based upon intake manifold temperature.

It provides an input voltage to the PCM, (Powertrain Control Module)
It's a Negative Thermal Coefficient sensor, (NTC. It uses two wires)

Meaning, as intake manifold temperature Increases, resistance in the sensor increases.
(Less voltage)
As the temperature Decreases, resistance in the sensor Decreases. (More voltage)

The PCM then uses this input to calculate the following;
1.Injector-Pulse Width
2.Adjustment of spark timing.

Just thought you might want to know.

Wish I knew what size your engine is.
A. The IAT in the 3.7 Liter engine, is located in the Left side, {Drivers} of Intake Manifold Plenum. (BEFORE the throttle body)

See that plastic 'snorkel' tube, that comes from the air cleaner housing, and goes to an oval shaped aluminum housing? That oval shaped, {On the end}, housing is the Intake Manifold Plenum.

The 4.7 Liter engine has the IAT in the same place.
The 4.0 Liter has the IAT installed INSIDE, the Front of the Intake Manifold Plenum. (Before the throttle body)

The color of the two wires are Brown with a Yellow stripe, (Thick 20 gauge wire), and Black with a Red stripe. (Thinner wire. 18 gauge)

SOURCE: How do you replace a Drivers side headlight bulb 2006 kia spectra

Helps to remove the battery, but small ahbds can do it.

Directly behind the lens is a big round cap ... twist it off. The bulb is held in place with a spring that locks in to a notch in the holder. When handling the new bulb, don't touch the glass. The oil from your skin will cause it to shatter when turned on.

What two wires on my iat do i hook up my innovative performance chip up to in my 2006 toyota tacoma


your what ? into what ? on to the alternator of a toyota

The implicit-association test (IAT) is a measure within social psychology designed to detect the strength of a person's automatic association between mental representations of objects (concepts) in memory.

the proper way to hot chip tune is replace the main chip inside the toyotas ecu

external plug in performance chips have been proven useless

I have a 2008 Pontiac G5 I was wanting to install a performance chip to it. It says to connect it to the IAT senor which has 5wires witch wires are for the IAT


The other three wires are for the Mass air flow sensor . That's a new one for me , performance chips or turners are used through the DLC . You program the engine computer . I have no idea what they can do from the intake air temp. sensor .The tan an lit blue wires are for the IAT sensor !

Where is iat sensor on 2006 toyota tacoma 4.ol 4door located ?


This is the 2001-2012 Toyota Tacoma wiring diagram, Toyota Tacoma IAT (Intake Air Temperature) Sensor Location and the Toyota Tacoma MAF (Mass Air Flow) Sensor Location, also included is a pinout of the sensor. You are likely installing a performance chip or a cold air intake kit for increased HP (Horsepower). You will want to be sure to disconnect the car battery before adding performance products.




Here is the Toyota Tacoma's Iat sensor diagram:

You have to contact the mfg of that product

It won't do a thing for your vehicle

Waste of money & may do some harm

Send it back

If you have no instructions that should send up
a red flag & G Force never has them apparently

My 2003 kia spectra comes up with P116 and P128 error messages. What do I need


p0116 is-- engine coolant tempurature ckt/range performance----- p0 128 is--coolant temp below thermostat regulating temperature. to fix these 2 codes are similar, change coolant tempurature sensor and thermotat all should be ok. make sure coolant in radiater is full. hope this helps you.

A code P0128 may mean that one or more of the following has happened:

  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature (ECT) sensor
  • Faulty intake air temperature (IAT) sensor

How do I install a performance chip for the IAT. Instructions say there are 2 wires to jumper but the IAT has 4 wires. The resistor has to go across the IAT wires.


that "performance chip" is not good for you car. that resistor is trying to make your car think the air coming into the intake is colder than it is, thus making your car use more fuel to perform better. slightly feel like more horsepower, use more gas.
