    I can look it up in a minute and tell you, but just out of curiosity, why do you want to know? I see this question come up all the time, for all kinds of cars. I've been a mechanic for 35 years and I've probably only ever replaced 3 of these over the years.

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.

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

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.

IAT sensor plug 2004 Ford F150...is it located seperately or is it integrated in the MAF plug? I see a separate set of two wires but I don't know? It's the standard 5.4 L V8 on my supercrew Lariat.


The MAFS and IAT are in a single connector on the 04-08 MY F-150s.
This is for a new body style 2004, not the Heritage / Lightning models.

The IAT sensor is the Gray w/ Red stripe & Gray wire pairs in the connector. The connector is a 6 pin ( 1 row of 6 pins ) black connector.

2003 911 carrea has fc p0113 intake air temp sensor high out put has new air mass. sensor replace fc come back .please advisor for further diag.


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)
