2018 JK Low tire pressure warning keeps coming on

On my wifes 2018 the front right tire pressure warning keeps coming on. It is usually a result of it getting cooler outside thus causing the pressure to drop, but it seems overly sensitive. When I put air in it then it only takes 1-2 lbs at most to fix the issue. If it is a leak then it is a really slooooow one as it will be OK for several weeks. The issue seems to be the weather causing it.

Is this a know problem and maybe a bad tire sensor? Is there a range on these sensors or a way to adjust the sensitivity in the programming. This is still under warranty and I plan to have it looked at Saturday but would like to know if there is anything I need to ask them to do.

What pressure are you setting it to?

How much do you trust your gauge?

Do you have the EVIC system/tire pressure display and, if so, what does it say compared to the gauge?


Our OEM tire pressure sensors and displays have been flawless in our two current Jeeps (12' WK2 and 16 JKU).

As a matter of fact, the systems are within about 1psi of the gauge.

I have two gauges, a digital and analog stick gauge and both read the same

I do not have the EVIC system, it only show a tire warning light and message with which tire.

I have an appointment this Saturday to have it looked at.

Iowajack-

As convenient as TPMS sensors are when they are working, they can sure be frustrating when they don't. Wanted to give you a bit of info in an effort to help with the situation. Sensors are a very simple sending unit, so they either work or don't. If the light comes on when the tires lose air, then the light goes off when you fill it, it indicates a functioning system.

You mentioned outside temps which is a very valid thought. One thing you could try is wait until the tire is cold to inflate it, since hot air expands, if you are filling it to 36PSI when the tire is hot, when the tire cools it could be dropping below the threshold and setting the light back off.

Other thing is our stores offer free tire inspections, we would be happy to remove the tire and dunk it to ensure the valve stem or tire itself isnt loosing air.

Why don't we start by confirming there IS an actual issue?

Op hasn't answered the initial questions.

What psi is he setting it too?

And how (cold or hot)?
