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: Installed new crate engine 1997 5.7 vortec, how do

The ignition timing is not adjusted with a timing light or with the engine running, and to set the ignition timing follow these proceedures.

There is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on top dead center. This "static" timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at top dead center.

1. Place the engine at top dead center.

2. Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing indicating the number one position.

3. With the engine on top dead center the ignition rotor should be pointing to the number one mark or notch that is on the distributor housing, if it is not then loosen up the distributor and turn the distributor until the ignition rotor is pointing to the mark or notch on the distributor housing and then tighten down the distributor, the engine should now be static timed.

If the distributor can not be turned enough to align the ignition rotor with the number one mark on the distributor housing, or the distributor does not set properly and will not allow the installation of the spark plug wires then the distributor is not installed correctly and is most likely a tooth off and it will need to be re-installed correctly. (The distributor should set like it is shown in the firing order diagram when it is properly installed)

Here is a firing order diagram to also help assist you.

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:

Iat sensor diagram maf groundthe


ok 95 , must be 16v as only that engine has MAF.
the sensor is on the air cleaner box, has 2 wires. and the ohms
is on the below page. as is the full schematic, and the maf wiring
is the cel glowing key on , and off driving 20miles? if not post the flash codes. DTCs.
the iat is the least important in fact the 92 its MISSING !
the maf tests are here. too. many tests,
suzuki sells a maf for $1000 (dogs) and the china one is junk.
so test it carefully or go broke fast.
IAT and ECT ( both read same)

Coolant boiling in resevoir.


It can be faulty coolant temperature sensor.Its not sensing exact coolant heat temperature so its overheating then required level.

Get the coolant pressure tested, its definitely leaking coolant. You will need to get the coolant running line.


Pressure test will help you to know from where exactly coolant/refrigerant is getting leaked.

2007 GMC 2500HD. TRYING TO FIND WHERE THE IAT SENSOR IS LOCATED. Is this on the lower left side of your truck under the hood. Does this have a 5 wire plug into the MAF?


Hello mahnkes.

You did not mention what engine you have.
I have based this reply on a 6.0 liter gasoline engine.

The IAT (intake air temperature) is integral with the MAF that is mounted in the intake duct and if defective will need to be replaced as an assembly.
#2 in the diagram below.

I hope this helps you along.
Let me know if your engine isn't the 6.0
