Where is Outside Temp sensor located for 04 4.2L
My LCD reading, displayed for the current outside temp. seems to be affected by engine heat,, the sensors reading changes by quite a lot, now the problem only occurs if I'm idling a while, like if i'm waiting in line at a drive thru it will go up 10-15 degrees, although my engine temp gauge won't change, after starting back driving a while its drops back down to the correct temp. I've done some work on my car and wonder if I didn't seal back properly something around were the sensor is located,, causing it now to be affected by engine heat, I don't think the part is bad as it gives right reading otherwise I just noticed it over the summer when display was on w/ ac running. anybody have this issue or know where its located??? thxs

Hi ControlIssues
That gets me in the right direction, at least, and may be reason why I'm having an issue, as I removed frt end to fix headlamps. and maybe I did put it back exactly right, or moved a covering or something allowing excess engine heat to come into contact with sensor.
Thanks again, Also If you know,,, Is there a diagram showing what area should look like. or most importantly the exact spot where sensor is,,, like what side of the lower grill its located on, do you know what is it called/looks like in case I need to find a part number.

I thought I found it, in middle of lower grill at fog light level, used a hair dryer to verify, but no temp change occurred, not sure if need to be driving for sensor to update though. so just want to verify if i'm correct.

I think the s-type sensor just not use to triple digit heat, now that our temps are under 100 I don't see that issue, over the summer anytime it was above 105 and I idled for a while the reading go up, once I got moving it would go down, I was thinking it was from engine heat, but now think could have been from road heat too, sensor is only 14 inches off the ground, or a combination of the things. my engine temp gauge stayed normal, my families taller suv don't have that issue in high heat. glad its not a problem.

Hi,
This item we are talking of, is not of complex construction. It is a temperature sensitive resistor, termed thermistor, that increases resistance in accordance to temperature, on a predetermined curve understood by the controller.
What is happening on your car? Is it truly picking up heat of the street? I believe that unlikely. You have not detailed the positioning you may have found this sensor in, is it in contact with a heat source? The A/C condenser perhaps? That device will run higher than ambient conditions while being operated. You did mention A/C operation in your original post.
A weak connection at the plug? Internally damaged wires, pinched, etc? Perhaps the sensor is beat? This thing is getting a bit old, and has seen some wear and tear. They aren't expensive, so you could just throw a new one in for good measure.
Keep this in mind, when electronic parts expire , their behavior becomes erratic and inconsistent toward the error produced. While currently the sensor tends to read high, should it begin to read low, the A/C will be held out, and your climate control will attempt to cool your cabin with mistaken quality of outdoor air.
