TPMS Situation...

[DWS44]

So...last week I traded in my old 2018 JLR that I had since new on a 2022 392 that popped up at my local Jeep dealer. As part of the deal, they agreed to swap my Fuel Blitz wheels & tires from the 2018. They made the swap a week ago yesterday. Drove it home, no errors, didn't think anything else about the wheels. Only time I drove it during the week was to take it to get the windows tinted on Tuesday. Drove it back home afterwards, no errors. Otherwise, I only fired it up to jockey cars around the driveway a few times during the week. All in all, maybe 10 miles driven since the wheel swap and no errors at any point.

This morning, I fire it up to take it out for a little while, and immediately I get "Service Tire Pressure System" error and the TPMS idiot light blinking. All the tire pressures showing "--". I'm trying to figure out exactly what went wrong here and curious if anyone else has a good guess. My two main theories from what I've read both here and the Google:

1. It appears that maybe Jeep came out with different TPMS sensors sometime in 2021? As such, maybe the TPMS sensors from my old 2018 aren't being recognized by the 2022.

-or-

2. I read some things noting that window tint can somehow affect these things?

I'm inclined to think #1 makes the most sense if they did, in fact, come out with different sensors, but I'm confused by the timing. If that was an issue, wouldn't I have gotten the TPMS errors immediately after they were installed? Is there a delay before the system would throw an error? At the same time, #2 seems like it might be a stretch, as I had window tint on my 2018, though on the 2022, I had the windshield tinted. Only had the windows on the 2018 done, none on its windshield. Again, drove it home with the window tint that day w/o any TPMS errors. As a test, I went back out this afternoon with the windows rolled down, which in theory would negate the window tint unless the windshield tint alone was the cause. It made no difference...the TPMS error persisted through the drive.

OK...I got long winded. Thoughts on any of this? If it's just the TPMS sensors, I'll probably bite the bullet and get them swapped out either at the dealer or maybe Discount Tire. (The latter probably cheaper option if they have any clue what I would be asking for) Hate to go through all that just to find out the window/windshield tint was causing it. I do have a Tazer Mini on the way, so if it came down to the tint, I'd probably just disable TPMS with the Tazer (I think I read that is possible) rather than having the windshield tint removed.

How is it even possible that window tint could cause a tpms failure???

This. It’s sensors

 

[Reinen]

2018 and 2022 JLs use different TPMS sensors. The change was made in June 2021.

You just need to go to a tire shop and have the TPMS sensors swapped out and all will be well.

@DWS44

On 6/5/21 TPMS's changed from Schrader 29093 to Continental sensors.

If a 2021 JL was built BEFORE 6/5/21 you need Schrader sensors.

If AFTER 6/5/21 then you need the Continental sensor or the new Schrader 33500 "programmable" sensor that has the protocol for the newer Jeeps.

Consider going to www.tpmsbargains.com (decent pricing... and their stock is always fresh, known not to be counterfeit and they have very good customer support) and buying a set of new TPMS sensors and then have your local tire shop pull the old sensors and install the new ones.

Buy these:

Yes, you can turn off TPMS with your new Tazer JL until you acquire the proper TPMS sensors..

Schrader Sensors prior to mid-2021

Continental Sensors since mid-2021

The receivers are different too therefore they are not compatible. On my Jeep, when I changed to the correct sensors, the tire pressure system reset in 10 miles.

BTW, many places that deal tires have aftermarket sensors that are much cheaper than factory sensors.

 

[Jebiruph]

Reach out to your dealer, they're probably interested in swapping sensors with you.

 

[DWS44]

Thanks to all that replied! I figured it was probably the sensors, but just making sure I covered all my bases!

Thanks for the link and info! Is there any advantage to the Schrader 33500 vs. the OEM Continental? Looking online, it appears the OEM Continental can be found for about the same price as the new Schrader. Also, does the "programmable" part mean that the installer would need to do something specific to make them work with the Jeep?

One more sanity check...the spare on the back has a sensor in it, too, right?

 

[roaniecowpony]

Yes, the installer would have to "program" them to the right frequency. No, there's no advantage to you.

Or you can just buy the non-programmable type that match your vehicle's TPMS frequency. Theoretically, the programmable type would allow single inventory for multiple use and save money. The reality is a wash.

Yes, the spare has a sensor too.

That is probably the answer. I am having a similar issue with my 2024 Jeep and I put on my 2023 Wheels and tires. Been to the Dealer 3 times already and still not fixed....

Yes, spare has/needs a TPMS also. That TPMS in the spare only when you use the spare in one of the 4 on the ground wheel positions.

In regard to the Schrader 33500 and the Contiental just install and drive and they are found and used by the JL/JT automatically.

You choice Continental or new Schrader 33500. Just be cautious where you buy from. Sure you may save a few $ but end up with old or counterfeit TPMS's.

I myself only buy from tpmsbargains.com.

 

[Discount Tire]

You would be surprised! It's happened to me on more that one occasion. There are some mirror tint products that not allow the sensors to transmit to the dash TPMS module.

 

[Bobby Hank]

Yes, I would be very surprised.

Yes I would be surprised as because it absolutely cannot happen. This was an example from the OP of someone that does not know TPMS giving them a reason because they are not capable of fixing the issue so the old "blame it on something else" trick. See it all the time. Rhineback already gave the detailed answer. You simply have the wrong TPMS in for your year, make and model.

Yes, the installer would have to "program" them to the right frequency. No, there's no advantage to you.

Not exactly true. Yes if you buy them from the installer they would need to program the 33500's which is no additional cost (or should not be). HOWEVER most reputable online TPMS sellers will send them already programmed and ready for the installer to just install and you drive.

This!!

I had my new tires installed on my original Black Mopar wheels this past Monday, and they couldn't figure out how to get the beadlock portion out of my icon wheels, and even after I told them, they didn't have the right size bit to get it out. So they just gave me some free El cheapo aftermarket sensors for my original wheels. They work just fine, zero issues and 250 mi on the new tires now.

Best part is that didn't even charge me for them!!
