Question about Toyota Pickup

1 Answer

Thank you, I need to know, what two wires in the MAF connector, are used for the IAT sensor? I know that it is intragated into the maf sensor, but it still should exist there. I'm installing a performance modual, and the instructions advise that i need to connect to the two IAT wires. This is a 1994 toyota truck, 3.0 efi engine, 4x4

Check fig:-- Thank you, I need to - ea95610.gif
Also check another fig:-- 21e4802.gif

wires go to combo MAF/IAT sensor: a fatter 12V supply wire, plus IAT signal & ground, MAF signal & ground wires. With IGN key on & engine off, the IAT signal voltage (signal-ground) is:
2.92V at 89 degF, and
3.26V at 71 degF.
Wire number 1 and 3.Are used in IAT. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

    Sir, are you sure, that it is #1 and #3 wire on the maf ? I was also told that it is wires, yellow- black stripe, and brown-black stripe ? I looked at the wires on maf connector, and #1 and #3 wires are not my colors? Just please tell me what why I should hook this up ? Should i go with colors or go with your #1 #3 wires ?marc steele

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.

Which are the functional iat sensor wires on an accordd 2008


It all depends on which engine your Accord is equipped with. This is really nice-to-know information when you are asking somebody for help with your engine control circuits.

For the 2.4L engine: At the MAF/IAT sensor connector, Pin #4, GREEN/BLACK is the "sensor ground" and Pin #5, RED/YELLOW is the "sensor input" for the IAT.

For the 3.5L engine: At the MAF/IAT sensor connector, Pin #1 GREEN/YELLOW is the "sensor ground" and Pin #2 RED/YELLOW is the "sensor input" for the IAT.

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).

I need to know which wires from my air box plug are the IAT (Intake Temperature Sensor) and which are the MAF (Mass Air Flow) wires.


sorry i do not know the colours off the top of my head, but the IAT it the small 2 wire sensor about halfway up the air duct, and the MAF is the large multi wire connector close to the air filter box. good luck!

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.
