On top of the intake manifold. #20 on this image.
Most vehicles do not have an IAT sensor. there is a scam on eBay right now trying to get people to buy a "Chip" that well give ur car 20+ horsepower. these 2 wires are nothing but radioshack resistors. Almost everycar has a MAF (mass air flow) indicator, not an IAT, so therefore the chip does not work, and u can not send it back or get a refund.
it's on top of the engine close to where the thermostat is.it does have two wires 18 or 20 ga.
is located in the intake is a two wire sensor is really hard to miss is located in the intake is a two wire sensor is really hard to miss ________________________________________________ The IAT is built into the MAF sensor right after the filter box.

Behind the throttle body opening under the throttle position sensor. Takes Torx t-20 bit to remove -- 2 screws, use Torx bit on a 1/4" socket drive with a 1/4" socket to break seal on Torx screws.
scrap it 20 pound

1. temperature sensor could be going bad 2. thermostat misbehaving 3. instrument panel malfunction you can test the temperature sensor with an ohm meter and placing it in hot water. should only be 20 bucks just replace.

0113 Intake Air Temperature Circuit High Input The IAT has told the computer the air temperature is -40 degrees. It can be a faulty IAT sensor, a faulty computer (PCM), or the wiring in between. Until the reading is accurate the computer will use a default value of 140 degrees. The sensor is in the air duct just past the air filter box. Check for a disconnected wire or poor connectionat the sensor. With a scan tool, tests can be conducted to determine the faulty component. Here's what you can do without a scan tool. The IAT is a variable resistor, cold makes it gain resistance. You may check the IAT with an ohmmeter, it should not show 100,700 ohms (unless it's -40 degrees outside). If it shows 100,700 ohms, replace the sensor. 23 degrees is 12,300 ohms. 50 degrees is 5,670 ohms. 86 degrees is 2,238 ohms, 212 degrees is 177 ohms. The code is indicating a very high resistance in the sensor, or an open circuit (broken/disconnected wire), or hopefully not the computer. If the sensor's conductivity does not match the air temperature (it will have some resistance unless it is 262 degrees), check the wires. (Make sure key is turned off at least 10 seconds and remains off before disconnecting/connecting PCM connectors.) The two wires both go into Connector 2 (Black) on the PCM (on the right fender). The signal wire (tan) is pin 20. The ground wire (gray) is pin 28. Use an ohmmeter to check the continuity of each wire. Probe from the tan wire at sensor connector (A) to pin 20 of connector 2. It should have no resistance. Likewise, probe from gray wire at sensor connector (B) to pin 28 of Connector 2. It should have no resistance. If the wires check out, wait a couple of days and see if the light goes out. If not, you can go buy a new IAT sensor (even if it did not have infinite resistance) since the only other option is the big bucks PCM. Or you may take it to the dealer and have them diagnose it. But failing all else I would try as a 2nd to last resort replacing the IAT sensor. Check the connector at the sensor carefully for a bent or backed out pin, corrosion. It most likely is a bad sensor, or a bad connection.
It should be directly on the outside of the Air Intake box (where your air filter is). It is a small (about 2.5-3 in long) black sensor that fits into a hole on the Air Intake box. It has two (2) female connectors that accommodate the a two-pronged plug. (there are only two wires on this year model) In later models, (like my 95 T100) the IAT sensor is built into (and part of) the MAF sensor, located right behind the Air Intake box. There are good pictures of it (and the location) in the Haynes Repair manual for 93-98 T100 (and also Tacomas, and Fore-Runners) on page 6-14 I paid about $20 at Advance Auto (or maybe it was AutoZone) and has been well worth it.
I am a 20 year old girl and I was quoted £1,200, of course I bought the quote, cheap as chips for my age.
