This is just a routine service reminder, it can be reset by pushing the step button until you see 0 miles to service displayed, then just hold down the reset button.

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)

First, make sure you can turn the engine by hand. If you can't then the starter can't turn it either. Have someone else turn the key and look for the source of the click...may be a relay. Go over the starting circuit with a volt meter. Check for power at the starter main terminal and then with the key turned to "start" check for power at the trigger terminal on the starter. Check battery voltage and check relay operation.
You have a neutral safety switch on the transmission if its an automatic and a clutch switch if it's a stick. Check them as well. Make sure battery grounding on fender and block are also clean and secure.
