TPMS rear driver wheel won't register.

[digimark]

2021 JLUR 4xe on 35" Nitto Ridge Grapplers and Method Grid 17" wheels. Replaced all the wheel TPMS valve stems, they all register fine at every other location, including after full air down/up cycles and rotating the wheels around to different positions. It's been to the dealer and they agreed the rear driver wheel isn't registering, they replaced the TPMS rear axle receiver box, no change. They said it has to be something about the wheels/tires and said I'd have to revert to stock wheels and tires. Not going to do that. I have the TPMS alerts disabled with a Tazer JL Mini for now, so I don't have to stare at the TPMS dash light, but I want to use it with my air compressor so I can't decide which is more annoying.

Has anyone had any luck possibly relocating the axle receiver closer to the driver's side or any kind of antenna enhancement to the radio to pick up the missing signal? I'm a bit frustrated.

sounds like faulty tpms sensor. I relocated my reader closer to the passenger side of the jeep when i installed my lift and the synergy E-brake relocation bracket. no issues at all. I also believe there is two readers one in front and one in the rear.

First of all swap two wheels. Doesn't really matter which ones. Air down 10 psi and go drive. See if the new lower psi registers. Also see if the same location is not showing or if it moved where you put the one that was not reading. If the dead psi reading moves with the tire then just replace the TPMS. If it does not move then it is a Jeep issue.

Also not confident the dealer replaced the "receiver" as opposed to replacing the TPMS with the wrong one.

That receiver isn't going to go out that soon on a 21 and with after market wheels I do not know of any Jeep dealer that would swap that part out with aftermarket wheels. Way easier to just blame it on aftermarket TPMS and send you on your way.

I have the exact same issue. Les Schwab has changed the sensor twice and it wont register left rear tire. Of course its under warranty, but if its the sensor, its not covered.

Edit: They've used both the newer and older sensors since mine is a '21. But I'm pre June, so it should be the earlier sensor. I'm going to have to take it back and see what they think.

If yours is pre 6/21 build it for sure is the older Schrader version 29093

If some dealer would of told me that I would of grabbed any OEM wheel off a new untouched wrangler. Install it and see if the TPMS works at that location. Eliminate them blaming the aftermarket wheel. I hate when a lazy dealership is quick to cover their incompetence and blame you for an upgrade.

No need to drive anywhere. There is no drive for 5-10 miles for calibration, the reading and reveal of psi is instant if it works. Hopefully there is another dealership you can go to, I would not got the the one who told you that.

I have 35” Nitto recons on 17” method bead grip wheels on my 22 JLUR no problem.

Almost accurate. It is not instant. You need to drive to get the wheel spinning so basically about 100 yards is all.

Thanks for the replies (and oops about the wrong subforum to post in, sorry.) We've moved all the tires around, substituted others and its always the driver's side rear position that doesn't register. The dealer agreed its not the sensors (early 2021 sensors). I think they just couldn't figure it out and decided its my problem. I installed an Epic Kraken/ARB compressor system under the passenger seat and wanted to use the TPMS readouts for pressure readings.

Same, moved tires around and always the drivers rear tire is not reading anything.

As others have found out, TPMS is much more reliable after driving 100 yards. Static it's very unreliable with the engine off. Engine running it's not entirely reliable but more reliable than engine off. My guess is engine vibration helps..

I've got beadlocks which limits me to 25 PSI and the TPMS often fail. I need to pump the tires to 28 PSI and drive a few hundred yards for them to register.

I wanted to chime in here since I was having this same issue, and since nobody has posted a resolution hopefully this helps someone else in the future.

I was running 35s on aftermarket wheels for years with no issue, and then suddenly one day the driver rear stopped registering on TPMS. I drove it like that for the better part of a year with a couple of rotations in there, and still it always failed to register the driver rear no matter where I moved the tires.

Last week I pulled my factory wheels/tires out of storage and put four of them on. I left the 35/aftermarket spare on the rear. I drove around for a few miles like that, and STILL the rear driver refused to register. Everything else was fine.

Finally I removed the spare and left it at the house. Drove around for another mile or two, and finally at the end of that drive all four tires showed up correctly on the TPMS.

So if anybody else has the same problem, my first suggestion would be to take the spare off of the back and drive around for a bit and see if it sorts itself out.

Yes, good you finally figured it out... I have been posting about this .... this how to, for years..

I still have that problem but just resigned myself to the dash light staying lit. I had my first flat on a trip out West in August and drove around for a few days with no spare on while I was waiting for the replacement. I can’t recall if I noticed any change. I’m willing to try taking the spare off after winter but not sure what it would tell me about the cause — if the spare interferes in some way — but I wouldn’t want to drive w/o the spare usually.

In theory you should only need to take one short trip without the spare for it to sort itself out, and then once everything is working you can put the spare back on and everything will continue to work. In practice if you already had a flat and drove around for a while without the spare and it's still happening, then maybe you have something else going on. It might be worth trying to remove the spare again and then doing a cycle of: air down / drive / air up / drive. See if that helps with the spare off.

As stated above you don’t need to drive around all winter without a spare. Just take it off while doing the relearn and then once all have been relearned install it as usually. The spare TPMS will then eventually go into sleep mode.
