Outside Temperature Display

[CJ SCION]

Got in the 2024 JLU for a ride to a new to me restaurant. Saw that the temperature display indicated 19° F, certainly didn't feel like it. Well, I checked it against the Davis Instruments weather station right here at home, the JL reads 5-6° less than the weather station. Close enough for me and glad to have determined the discrepancy.

How does your display read compared to another known source?

mine is almost spot on.

You can tell the difference between 19° F and 25° F? I'm not sure that I'd be able to.

I have faith in your ability, you can do it. It's simply a matter of awareness.

Worked outdoors in Michigan year round and recreate outdoors just about as much. Heck I can do it in my sleep, unfortunately. One degree either way and the wrong bed cover will ruin a nights sleep here.

I haven't checked the accuracy of the temp display. It's just not that important to me.

MIne is within a degree or 2F on startup compared to garage temp thermometers.

I find mine, will read high when I first start it up. like it remembers the temp when I parked it. Will be below freezing in the morning, and I will start the Jeep, and the temp will say 50 or 60 degree's.

mine said -15 this morning.
it was -15 this morning.

Mine reads correct enough, but the strange thing is for example ... The trail head is 76, I put it in 4L, and go up over some pass where it is in the 50's, the temp will still read 76 ... until I take it our of 4L.

Why the Temp & 4L would be linked is beyond me.

I’ve had that happen to me too. Temp gets stuck and won’t update.

There are 2 banks down the street with temperature on their signs and my temp gauge is within 1 or 2 degrees of those.

it is not the 4L it is the speed or lack of. it actually stated in the owners manual that the vehicle had to be driven over a certain speed before it registers...

Good catch!

Still makes no sense to me, but at least it is expected behavior.

We did a Jeep Adventure Academy day a few years ago and I asked them about this - they said that the temp sensor is de-activated when in 4L because you're probably running real slow, causing heat buildup in the engine bay which would cause a false temp reading.

Ok, that makes sense ... Bit instead of deactivating, they should have moved the temperature probe somewhere where the engine temp isn't an issue.

I bought a thermometer and put the probe on the back side of the front bumper, and it generally does a pretty good job of not picking up the engine heat
