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.

Replaced the MAF. Still have the P0113 code. Car runs fine. Cannot find another intake air temperature sensor anywhere on the vehicle! Where is it?


code p0113 does not refer to a MAF sensor so replacing that was a waste of money=== It refers to intake air temperature (IAT) sensor---circuit malfunction====causes --wiring open circuit/short circuit to positive--wiring short circuit to ground---ground wire defective---IAT sensor---ECM.
Replace the IAT and check the wiring is in good condition and the connectors are clean and tight.

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)

PCM has failed .Here's the code for your problem,it may be a maf sensor. The MAF is mounted in the intake air hose of the air cleaner assembly. On some vehicles, it is combined with the IAT sensor.

Have you checked the cam sensor? Also does that vehicle have a "throttle position sensor"? Some cars use both MAP and MAF sensors, not sure about your particular vehicle but if it is one of those, cleaning the MAF wouldn't hurt. Good luck.

Hi, I own a MB C230 Kompressor 1999 (123,ooo miles).Two days ago, check engine light came on. DTC was P0170 (fuel trim malfunction bank 1. I took out the MAF sensor and cleaned it using MAF sensor...


CODE PO170 - FUEL TRIM BANK 1 MALFUNCTION. POSSIBLE CAUSES TO YOUR PROBLEM. AIR LEAKS IN THE INTAKE MANIFOLD. EXHAUST PIPES OR EXHAUST MANIFOLD. FUEL CONTROL SENSOR IS OUT OF CALIBRATION ECT IAT MAF. LOW FUEL PUMP PRESSURE FUEL FILTER CLOGGED FUEL PRESSURE REGULATOR FAULTY. ONE OR MORE INJECTORS RESTRICTED OR FUEL PRESSURE REGULATOR FAILED. HO2S ELEMENT IS CONTAMINATED DETERIORATED OR HAS FAILED.LOOK FOR VACUUM HOSE DISCONNECTED BROKEN LEAKING OR LOOSE.CHECK THE MASS AIR FLOW SENSOR SIGNAL CIRCUIT. SHOULD BE 4.8 - 5.2 VOLTS.IF SIGNAL CIRCUIT LOWER VOLTS LOOK FOR SHORT TO GROUND OR AN OPEN HIGH RESISTANCE IN CIRCUIT.IF YOU ARE 12 VOLTS FROM SIGNAL CIRCUIT PCM IS FAULTY.BEFORE SPENDING A LOT OF MONEY TAKE VECHICLE TO GARAGE OR DEALERSHIP.LET THEM TEST IAT AND MASS AIR FLOW SENSOR PARAMETER FOR THE CORRECT RANGE OR HZ USING A VARIABLE SIGNAL GENERATOR TO SEE IF IAT MAF SENSOR GOOD OR PCM FAULTY. THIS WAY YOU WONT SPEND TOO MUCH MONEY.

Where is the IAT sensor on a 03 Ford Taurus,3.0L. flex fuel?


You don't change parts when you get a code. The codes are a starting point for diagnostic testing.
Codes are the symptoms of a possible problem,such as an out of range or defective sensor. Codes don't mean you change something. It's not that simple or are vehicles designed as such. You always test,then replace. You can't do either, if you don't know the system your working on.
The MAF and IAT Sensors are both in the MAF,one piece in most cases.

What are your issues ? Not likely a MAF gone bad.
Do you have the air filter cover on tight and no duct work leaks or vacuum leaks? That's what's possibly setting the code for the MAF.

Ford explorer ,4 litre. have code of P0171


You could be right but before going to all that trouble of replacing the intake gasket take a close look at the MAF (Mass Air Flow) sensor. Also look for a vacuum leak downstream of the MAF sensor. The MAF sensor may be dirty especially if you are using an "oiled" air filter and it was over oiled. Remove the MAF sensor and clean it with electronic cleaner. Make sure it is dry before reinstalling. If it is damaged, replace it. Also replace the fuel filter as a partially clogged filter has been know to set this code on some vehicles. Check all vacuum hoses and replace as necessary.

Could be a plugged catalytic converter or a plugged fuel filter, run an exhaust back pressure test, any muffler shop will do this, most times for free, the other thing to do is have the fuel pressure tested under a load, also clean the MAF sensor, a little dirt on the sensor wire wrecks havoc, You didn't leave anything in the intake runners did you? have seen seasoned technicians do this more than once.
