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.

Related TP Sensor engine DTCs present Intermittent wiring or connector problem TP signal circuit is open or is shorted to battery voltage or to 5v supply circuit TP sensor has failed TP sensor ground circuit is open PCM has failed IAT Sensor is damaged or it has failed (an internal open circuit) PCM has failed

Please specify the year, make and model of your vehicle to give the exact location.

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)

- ZJ-Secc-25-Emission-Control-Systems
- ZJ-Secc-8W-Wiring-Diagrams (page 62)

Hope helped with this; good luck (remember rated this help).

RADIATOR FAN WORKS OFF OF THE COOLANT SENSOR NOT THE IAT SENSOR. CHECK YOUR RELAYS AND ALSO SEE IF IT COMES ON WITH THE A/C AS THIS OVERIDES THE COOLANT SENSOR FOR THE FAN. MOST LIKELY CAUSE WOULD BE A FAN RELAY
