TPMS Syncs then drops off

[mrworldwide79]

I picked up a set of rubicon take offs to put on my ‘21 Overland (built after June 2021). Only one of the 4 tpms sensors reads consistently. The other 3 will read if I toggle tpms off/on using a tazer but after driving for awhile they no longer read and I get the tpms warning. At least, I think they are reading initially. I have changed the psi in those 3 tires to see if the change is reflected on the tpms system and it is initially but then drops. Anyone else have this issue? If so, how’d you fix it? I’m close to just having 3 new sensors put in.

just started having this issue with my DS and rear PS (all four reading the same on the screen, only FPS is ok), I'm going to check my pressure tonight, top up and see what happens

I aired down to 30psi then back up to 37 to see if that triggered. Hope it works out for you.

Wasn't there a change in the TPMS sensor part number in the summer of 2021?

There was. The guy I bought these off of had a post June 2021 build like I do. One of the sensors reads fine, 3 do not.

Perhaps silly question, but have you tried rotating them?

not silly, and I should have said that in my initial post. I did. Same tire still the only one that consistently picks up.

That's what I was curious about -- if it follows the tire or remains at the same corner. Might be worth stopping by a local tire shop to see if they can pick up the other 3 with their scan tool.

Agreed - you've done all of the smart logical things already - tire rotation, changing pressures and so on.

Thanks. Was hoping there were other tricks I hadn’t thought of but looking like I’ll bite the bullet and head over to the tire shop.
