JFK TPMS Issue?

[NatersXJ6]

Hmm... This seems odd to me.

I've gotten into the habit of using the TPMS to see all of the individual pressures in my 2014 JKUR when airing up or down. I've rotated tires many times and never had the system fail to recognize a tire.

this morning in Death Valley I aired down quite a bit for running around on the washboard (very washboard) roads. My dad was watching pressures and calling them out to me, so I did not see what wheel was sensing as the pressure fell.

when airing back up 10ish hours later, the front wheels were reversed! left displaying on right, and so on... Rear wheels normal.

I am gifted enough to be able to compare the picture on the screen to the actual tire hooked to the compressor... This was weird.

any similar issues or solutions? I'm temped to disconnect the battery and see if a "reset" helps anything?

Thanks,

Nate

I'd try and see if the battery disconnect for a bit will help. Maybe un-mount the front wheels and move them far away to try and reset them?

Also, I believe most tire shops have a wireless tool that does a reset on these as well. I think Discount did that to my JK a few years ago...

:sombrero: When you airdown, you should use an individual pressure gage/or preset staun type-and

Airing backup, individual pressure gage, for OBA or mobile compressor-

I would never depend on Chryslers TPMS systems accuracy !

It's all in the title

I think the issue is based on using JFK TPMS.
Back in the mid 50's JFK was considered to be full of hot air. It wasn't until his presidency, that things cooled down... Cuba excluded. :elkgrin:

When airing down I've noticed the Jeep TPMS to follow the gauge fairly well, but airing up is a different story. Usually I have to drive a short distance before the monitors accurately reflect current tire pressure.

As Jimbo said, a quality pressure gauge is the best solution when airing up and down.

Yes, I'm especially proud of Apple for managing to make me look like an idiot with their spell check technology. It saves me a lot of time over doing it myself.

Despite all the gauge advice, and I do not wish to engage in any discussions of precision and accuracy in relation to optimized tire pressure, I'm still confused by reasons why my system would reverse the display and signals.

I had the battery disconnected for an hour today, so I might check it again tomorrow and see what has happened.

Superb post :beer:

I also hate Apple autocorrect which once corrected "whatever" with "Byzantine" no joke. I think you're on the right track by leaving the battery disconnected for a while then driving the next day. I've had some odd readings and false low pressures that were remedied by disconnecting the battery.
