Iat sensor Im trying to find the Intake air temp. sensor to install a performance chip..can you help..michael

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 !

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:

Go back to the chip supplier. they should have provided instructions.

IAT sensor only has 2 wires ,intake air temp. Maf sensor has 6, mass air flow

Hi Terry:
The IAT sensor is a thermistor which supplies intake air temperature information to the PCM. The IAT is located in or near the air intake duct.



Fig. 1: On VIN 8 engines, the MAT (or IAT) is mounted in the intake plenum




Fig. 2: On most vehicles, the IAT sensor is threaded into the throttle body extension

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

sometimes the air temp sensor is in the mass air too.

please rate as problem solved if this is what you need.



Section 03-14: Engine Controls, Electronic 1994 Mustang. Workshop Manual
REMOVAL AND INSTALLATION Intake Air Temperature (IAT) Sensor Removal and Installation

1. Disconnect battery ground cable (14301) .

1. Disconnect engine control sensor wiring (12A581) from intake air temperature sensor (IAT sensor) (12A697) .

1. Remove intake air temperature sensor from air cleaner outlet tube (9B659). (This is the tube that goes from the air cleaner to the engine.)

1. To install, reverse Removal procedure. Tighten intake air temperature sensor securely.

THE INTAKE AIR TEMP SENSOR IS INSIDE THE MASS AIR FLOW BOX(NOT SERVICED SEPERATLY)

Yes. That is exactly it. The Air Intake Temp Sensor is built into the Mass Air Flow Sensor on the Air Filter Box. Below is a picture...


I personally have not connected one of these Chips to a Tahoe...What I can provide you with, is the Connector Diagram so you know exactly what Wires you need to Splice in to. See below...

I hope this helps you. If you have any more questions or need any more diagrams, please don't hesisitate to ask...Thanks again, JShreader.
