We will keep posting information on the most popular searches. Here is the information on the Ford Taurus IAT sensor location, wiring and relative resistance vs. temperature values.

LOCATION

The location of the IAT on the Ford Taurus varies, so here are the 3 most common areas:

1 – On models from 1996 through 1999, the IAT sensor is separated from the MAF sensor and has a 2 wire connector, as shown in the following illustration:

2 – The following is an alternate area where you will find your IAT sensor on the 1996 – 1999 Fort Taurus.

3 – On models from 2000 through 2002 and later, the IAT is integrated in the MAF sensor, which is installed in the air intake duct and has a 6 wires connector. An example is shown below:

WIRING

On the 2-wire IAT, wiring is easy. You will identify the two wires by their color. One wire is [GRAY} and the other is [GRAY with RED].

On the other hand, the 6-wire IAT, there are 4 wires for the MAF, 1 wire for the IAT and one wire is common ground. The wire connecting to IAT is wire #6 and it is plain GREY in color.
If you are planning to do something like connecting an IAT resistor, you can:

1) disconnect the plain GREY wire (#6) from the MAF and connect it to one of the terminals of the resistor and then, the other terminal from the resistor can be connected to wire #3, which is the common ground.

IMPORTANT: When connecting one of the resistor terminals to wire #3, DO NOT disconnect it from the MAF. Disconnect from the MAF wire #6 (GREY) ONLY, which is the one that goes to the internal IAT on the MAF.

The circuit should be like the following drawing (thank you Mike  for pointing out an error with the diagram below):

RESISTANCE VALUES

Resistance values versus temperature kept the same in all models from 1996 through 2002, and possibly the same on newer models, but at this time that has not been verified.
