My 07 Tiburon has a p0113 and p0113p. I already replaced the iat sensor, cleared the codes but they just came back. Any thoughts


code p 0113 refers to intake air temperature (IAT) sensor---circuit ,malfunction=====causes --wiring open circuit---wiring short to positive---wiring short to ground--ground wire defective---IAT sensor--ECM
check the harness connections , corroded pins, water in connections

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 !

I have a 2009 Honda Odyssey. Please show me the color code for IAT sensor, and its position. Thanks


IAT, is the air temp.
this sensor varies by what engine you car has. (and country)

you could just log i to alldata.com and look, its all there.
3.5 L V6 this engine? is common in USA>
out side USA is this
It is equipped with a 2.4 L engine and CVT
vast diffr. engines... no body ever post engine or country so i must as
the questions.
why are you worried, about IAT, just a clue, helps.
the scan tool said its bad?
ok , i logged in for you, looked up this sensor
and this 3.5L has a MAF, Air flow meter near air cleaner.
and guess what , the IAT is inside the MAF !!
why not post the why so we can help,
post symptoms. or, scan codes, or? really

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.

The wires on my mass air flow sensor were broken (3)of them could you help me out as my new pigtail has different color wires and i would like to make sure i wire it right


Hi, does the sensor have letters A-E on the terminals? Normally the connector on the harness should slip right into the sensor. Does your sensor just have wires to be soldered--no receptacle? I have pasted the harness wire colors below for the 6.0 liter engine, including the terminal letter for each wire. If the sensor does not have letters, you will need to run a test to see which end begins with terminal "A". Since terminals A and B comprise the IAT, which is a thermister, you could use an ohmmeter on the 2 end terminals to see if the resistance changes with ambient temperature. Do not touch either sensor, but blow hot air on the IAT to see if the resistance changes with temp. Whiched 2 end terminals yield this temp sensitivity are terminals A and B.

I have a 03 mitsubishi eclipse 2.4 what colors belong to the IAT sensor


Color wires? The IAT sensor is part of the mass air flow sensor. The wires in the MAF harness that go to the IAT sensor are: Brown is ground, Red/Purple is the 5v reference, and Green/Yellow comes from the IAT into the Atmospheric Pressure Sensor and out to the computer.

Hope this helps. Good luck!

I have 5 wires going to mt IAT sensor. i need to know which 2 wires lead to the MAF/IAT SENSOR.its a 2004 chevy tahoe z71 4x4 with a 5.3 liter v-8. im putting a computer chip on so need the color of the...


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

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).

Wire colors for my IAT sensor


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.

2007 gmc sierra 2500 IAT sensor


Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.
