All Tire Sensors Throw Errors

I have a 2015 JGC Overland. Whenever the temperature gets about 70 or above, it will throw a tire sensor error on all 4 tires. It recently started saying to check the sifter as well.

I've attached a picture of it happening. never in the winter, only as it gets warmer. When it is above 80, you can almost guarantee it to happen several times during that day. It will throw the error and then 2-5 minutes later it will reset back to normal.

I'm quite frustrated because I've taken it to a jeep dealer several times, and they "tell" me they are replacing things, but won't tell me what and always think it's fixed. I've wasted an enormous amount of time trying to get this fixed.

I even rushed to the dealer once when it was happening an extended amount of time and told them they should get a data reading while I have this happening. They took their time and 20 minutes later, just as they hooked it up, the sensor cleared.

I would love to get this fixed as it is quite annoying.

Any suggestions or anyone have this and got it fixed so I can tell my dealer how to fix it?

Thanks.

My theory is someone made that code to pop up on the dash. It's a man made code so why did he create it? I noticed if I hit a few bumps it kicks it back on and if I hit more it kicks it off again. What ever reads the sensors is lose or broken. Something has to read them to give the pressure to the dash board.

I would completely agree. I have found the same thing. If the sensor is in error and I accidently hit a bump, it immediately cleared. But... I think it's also temperature tempered. I don't ever get an error in the winter. Only when 70 or above. I'm guessing there is an exposed wire or something sitting next to metal that gets hot and throws the error. What frustrates me is that my dealer said they've replaced almost all the components by now. I don't think they really did or they would catch something exposed.

I doubt it's a wire.

Based on the fact that both temperature and vibration affect it, I would estimate it's either a relay going bad or a chip has delaminated from a logic board somewhere (possibly due to a bad soldering job from the factory that has started to fail). Either of those could result in issues during thermal or vibration induced stress.
