Hi

I don't know what the wiring colours are in Puerto Rico, but if one of the wires is red then that is the input, and if there is a yellow wire with a green stripe then that is the IAT output.

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: IAT and MAF info

I have the same "chip" (really just a resistor). It should be the wire harness that clips into the lower box of the intake. I believe it is a green and a black wire. Just unclip it and slide the end of the resistor into each wire prong. Then tape the heck out of it. I put a rubber cap over mine then electrical tape. Works like a charm

I have a lincoln town car 2003 I have this code po113 IAT sensor 1 circuit high input I changed my MAF and it started up but not like it should can someone please help me out


code p 0113 refers to intake air temperature (IAT) sensor --circuit malfunction===causes wiring open circuit / short to positive ---wiring short to ground ---ground wire defective --IAT sensor---ECM
the MAF ( mass air flow) sensor has nothing to do with the fault
the fault is in the wiring or the IAT sensor

Where is iat sensor located on 2006 tpyota tacoma 4,ol ?


Intake Air Temperature (IAT) sensor and Manifold Absolute Pressure (MAP) sensor are combined into a single assembly which is called Mass Air Flow (MAF) sensor. This MAF sensor is located on the air filter box near air filter hose, and is connected with a five wire connector. You cannot replace the IAT sensor alone. Instead a MAF sensor is replaced altogether.

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:

Where is the MAF/IAT sensor on a 2004 Chevrolet Silverado ?


You Tube Video--always go there,always

Google--always use that & read what is in print, for decades

In or on the intake plastic ducting between the air
filter box & the throttle body on ALL (98%) of vehicles
you can find the MAF,follow the wires

I would guess 90% have the IAT also inside & part of the maf

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)

For a 2005 GMC yukon 5.3L what are the wire colors that control the IAT sensor There should only be 2 wires controlling it but there are 5 on the connection as it controls the MAF and IAT with the sa


The intake air temp sensor is part of the MAF sensor so yes there are 5 wires.
The two wires that go to the air temp sensor are tan and black. The other three are for the MAF.

Diagnostic codes


P0102 OBD-II Trouble Code - Mass Air Flow (MAF) Circuit Low Input

What does that mean?
Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.

Symptoms
You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes
A code P0102 may mean that one or more of the following has happened:
* The MAF may be disconnected, or a wiring connection may be bad
* The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
* The MAF sensor may be faulty
* The vehicle computer may be faulty (very rare)

Possible Solutions
The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Inspect for any air leaks near the MAF sensor.
* Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
* Replace the MAF sensor.


P0113 - Intake Air Temperature Circuit High Input

What does that mean?
The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.

Potential Symptoms
There will likely be no symptoms other than illumination of the Malfunction Indicator Lamp (MIL - Check Engine Light / Service Engine Soon).

Causes
A code P0113 may mean that one or more of the following has happened:
* Internally failed IAT sensor
* Faulty connection at IAT sensor
* Open in IAT ground circuit or signal circuit
* Short to voltage in IAT signal circuit or reference circuit
* IAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.)
* Faulty PCM (less likely but not impossible)

Possible Solutions
First, if you have access to a scan tool, is there an IAT reading? If the IAT reading is logical then the problem is likely intermittent. If the reading is less than -30 degrees, unplug the connector. Install a jumper wire between the harness connector signal and ground circuits. The IAT temperature reading on the scan tool should be maxed out at the high end. For example it should be 280 degrees Farenheit or higher. If it is, the wiring is okay, and it may have been the connection. If it isn't install the jumper wire between the IAT signal circuit and the chassis ground. If now the IAT reading on the scan tool is maxed out then check for an open in the IAT ground circuit. If you get no reading at all on the scan tool, it's likely that the sensor signal is open or the 5 volt reference is missing. Check using a DVOM (digital volt ohm meter) for a 5 volt reference. If it's there, then unplug the connector at the PCM and check for continuity on the IAT signal circuit between the PCM connector and the IAT connector.

I really hope help with this (remember rated this).

My maf sensor pigtail was cut and stolen. I purchased a new pigtail from ford and I need to know the color codes so I can intall a new one. my vehicle is a 2004 ford f-150 lariat with a 5.4 liter engine....


As long as you are talking about the new body style ( 3V 5.4 L )

The module is the MAFS and the IAT sensors

The IAT section is :
PCM to IAT is Gray wire
The return to the electronic engine controls from the IAt is Gray w/ REd stripe wire

The MAFS
PCM to MAFS ( MAF ) is Light Blue w/ Red stripe wire
The MAF return on the PCM is Tan w/ Light Blue stripe wire
The ground ( same as the Charge motion control valve ) is Black w/ White stripe wire.

I have a 4runner and i would just want to know the wire color of the iat sensor...their are 7 wires on the maf sensor and i do,t know which are the wires for the iaty sensor


It should be a yellow wire with a black stripe, it is called the THA terminal and is on pin number 7 at the MAF. You can use pin 5 (brown wire with black stripe) as the return when making resistance measurements on the MAF (disconnect first)
