‘21 TPMS Reset

Caught the Bug
Well like every other friggin thing TPMS sensors had to get more complicated. I have a ‘21 Gladiator and I got new wheels, tires, and sensors. I guess the new sensors won’t ‘marry’ to my truck. I ran them for 50 miles at 35psi daily driving. I ran them for 20 miles continuous on the highway. I lowered the tires to 25psi, drove around and then filled them up with the engine running. Nothing. Any other ideas on how to get the new sensors (from Discount Tire, they warned me it was a weird system and would take a bit) to register?

The ones I bought on Amazon synced within the first 10 miles or so. I haven’t heard of the Jeeps being an issue, they very well may be, it seems you’ve drove enough so they may have either put in the wrong ones or not put them in. I think some brands might need to have the RF or whatever “flashed” maybe between discount and a dealer they can sort that out, but idk

OK y'all. Shout out to @Discount Tire in Raleigh! In the middle of model year 2021 (It looks like in June of 21) Jeep switched the programming of the TPMS sensors. So when you get new sensors there is a reference to 'Early Model' or 'Late Model'. Early 21's are everything with a build date BEFORE 06/21 which is on the plate in your driver's side door. Again the sensors are the same but they have a different program. The guys at DT took their scan tool and flashed my sensors from Late Model to Early Model and they lit up in 5 minutes!

in June of 21 they went to Continental TPMS sensors, most likely due to supply shortages. We are restricted to ordering some sensors . 1 in 7 days. so if you need a set of 4 and have not inventory well I guess you wait a month.(if no one is in line before you.)
 
Just looking around and found this thread about something I'm experiencing currently. I just had my local Discount Tire store install/mount/balance my new tire/wheel setup and my TPMS keeps throwing an error and not reading right after I startup my vehicle. So, I have a Tazer and disabled the TPMS for now but I think I'm gonna call my local DT store and have them rescan the sensors and make sure they are working correctly. My JT is a later build... I'll make sure to mention that as well when I go back. Thanks

I have a 2018 JKU RUBICON and I just put on Raceline Beadlocks. I removed the TPMS sensors from the stock rims and installed them into the new rims. I attempted to recalibrate the TPMS with out any luck. Any ideas.

Thanks

JL and JK are different. There is no calibrating on the JK. You just drive and they reset. Always quick. Maybe you installed incorrectly?

I guess that would be my next question . Can I install them incorrectly ? Does the sensor have to be pointed a specific direction?

Thanks again

Being that they were the original sensors and not even a completely new set, they should sync up just fine. Assuming you gave them a good drive on the highway as well? When installed the sensor lays pretty close to flat on the wheel. Other than that it's pretty straight forward.

Ok great. Thanks for the info. The one thing I did not do was take them for a decent drive.

Sensors are usually meant to be mounted only one way so they lay close to the rim. If they are backwards they stick out from the rim a may potentially be damaged while installing the tire and setting the bead.
