The Ambient air temperature is monitored by the Electronic Vehicle Information Center (EVIC) through ambient temperature messages received from the Body Control Module (BCM) over the Programmable Communications Interface (PCI) data bus network. The BCM receives a hard wired input from the ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a screw to the right side of the headlamp mounting module grille opening, behind the radiator grille and in front of the engine compartment. The ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
OPERATION
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent to it by the BCM. The resistance in the sensor changes as temperature changes, changing the temperature sensor signal circuit voltage to the BCM. Based upon the resistance in the sensor, the BCM senses a specific voltage on the temperature sensor signal circuit, which it is programmed to correspond to a specific temperature. The BCM then sends the proper ambient temperature messages to the EVIC over the PCI data bus.
The temperature function is supported by the ambient temperature sensor, a wiring circuit, the Body Control Module (BCM), the Programmable Communications Interface (PCI) data bus, and a portion of the Electronic Vehicle Information Center (EVIC) module. If any portion of the ambient temperature sensor circuit fails, the BCM will self-diagnose the circuit. A temperature reading of 130° F will appear in the EVIC display in place of the temperature when the sensor circuit is shorted. A temperature reading of -40° F will appear in the EVIC display in place of the temperature when the sensor circuit is open.
Cherokee Laredo, no. Grand Cherokee Laredo, yes.
There is no such thing as a 2002 Cherokee Laredo. The last year for the Cherokee was 2001, and the last year it came with the Laredo trim was 1992. I have a 2003 Cherokee Laredo so this awnser makes no sense at all. Do you have a GRAND Cherokee Laredo? Those are still being made. They are not the same as the Cherokee.
yes There was also a Laredo package for the XJ Cherokee in the 1990's.
it tells the radiator fan when to turn on
I mean how do you disassemble the fan blower in a 1998 Jeep Grand Cherokee Laredo. how do you remove the blower fan from the car in the Grand Jeep Cherokee Laredo.

Yes, Laredo is just a trim package.
Jeep did not make a Cherokee Laredo, they did make a grand Cherokee Laredo, and you can fit 31 inch tires.
It does have a computer, no programming should be necessary.

220.

No.
with a center not an outside puller also dont pry or hit on it for it will break
No, they will not interchange.
