The air temperature is taken between the air filter and the throttle body. Look in the roof of your air cleaner box. (usually 2-pin plug) After the air cleaner, the tube that sends the air to the throttle body has the mass air flow sensor in it.(usually 4-pin plug)

2004 Grand Cherokee 4.0L. Where is the temperature sensor located?


no symptoms posted, just and wide range easter egg hunt and no engine or transmission options stated "drive line" which.?

there are many temp sensors. on jeeps. and more each year it seems.
  1. EFI ENGine temperatures. ECT.
  2. transmission temperature (TCM input)
  3. outdoor air temp. (and option mine has... case in point)
  4. air temperature of the air inducted in to the engine (EFI IAT)
  5. HVAC , climate control temp sensors. at least 2.

post symptoms, then ask how to diagnose car.

Where is iat sensor on 2006 toyota tacoma 4.ol 4door located ?


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:

Where is the IAT sensor on a 1999 jeep grand cherokee limited 4.7L


great question, on some cars, its NOT THERE.
nice how you actually state engine option.
but way not post symtoms, or evidence. (got DTC errors from scan tool?)
fsm says.
4.7 quote:
The Intake Manifold Air Temperature IAT sensor is located on the left side of the intake manifold.
For a temperature of 68F (20C) the resistance is approximately 6000 ohms. For a temperature of 104F (40C) the resistance is approximately 3300 ohms. (this forum hates degrees symbols , dang)

its just a Thermistor. NTC

on some cars, its in the MAF
others its screwed in to the air cleaner box.
others, (yours) its in the air plenum. (MAP base EFI)
the map system needs the plenum baro and temp. TOGETHER.

1998 Jeep Grand Cherokee Laredo 4.oL I got a code po113


Trouble Code: P0113 (4.0L L6 VIN S Auto)
IAT Sensor Circuit High Input Print this code dataprint_icon_codes.gif Number of Trips to Set Code: 1
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
Check with ignition on or engine running; battery voltage more than 10v; The PCM detected the IAT Sensor input was over 4.90v (exc. Dakota, Durango, Ram) or 4.98v (Dakota, Durango, Ram) for 3 seconds.

Possible Causes:
  • IAT Sensor signal circuit shorted to VREF (5v)
  • IAT Sensor signal circuit is open, or the ground circuit is open
  • IAT Sensor is damaged or it has failed (an internal open circuit)
  • PCM has failed

Cant find IAT on 99 jeep grand cherokee laredo...


Intake Air Temperature sensor.

It has to be installed ->BEFORE the throttle body, to sense the density of the air entering the intake manifold, based upon intake manifold temperature.

It provides an input voltage to the PCM, (Powertrain Control Module)
It's a Negative Thermal Coefficient sensor, (NTC. It uses two wires)

Meaning, as intake manifold temperature Increases, resistance in the sensor increases.
(Less voltage)
As the temperature Decreases, resistance in the sensor Decreases. (More voltage)

The PCM then uses this input to calculate the following;
1.Injector-Pulse Width
2.Adjustment of spark timing.

Just thought you might want to know.

Wish I knew what size your engine is.
A. The IAT in the 3.7 Liter engine, is located in the Left side, {Drivers} of Intake Manifold Plenum. (BEFORE the throttle body)

See that plastic 'snorkel' tube, that comes from the air cleaner housing, and goes to an oval shaped aluminum housing? That oval shaped, {On the end}, housing is the Intake Manifold Plenum.

The 4.7 Liter engine has the IAT in the same place.
The 4.0 Liter has the IAT installed INSIDE, the Front of the Intake Manifold Plenum. (Before the throttle body)

The color of the two wires are Brown with a Yellow stripe, (Thick 20 gauge wire), and Black with a Red stripe. (Thinner wire. 18 gauge)
