* Behind the front bumper: This is the most common location. You might need to remove some parts of the bumper or air dam to access it.
* Within the front grill: Less common, but possible. Accessing it would require removing grill components.
To find it definitively:
1. Consult your owner's manual: The manual should have a diagram showing the location of sensors.
2. Use a wiring diagram: A wiring diagram specific to your Jeep's year and model will show the sensor's location by tracing the wire from the ECU (Engine Control Unit). You can often find these online through repair manuals or automotive websites.
3. Use a OBD-II scanner with live data: Some advanced OBD-II scanners can show the sensor's readings and potentially identify its location based on data acquisition.
4. Visual Inspection: Carefully examine the front of your Jeep, focusing on areas likely to have air intake for the sensor. Look for a small, usually black, temperature sensor connected to a wire harness.
Remember to disconnect the negative battery terminal before doing any work near electrical components. If you're not comfortable working on your vehicle yourself, it's best to take it to a mechanic.
