TPMS issue

[Rogue321]

I have a 2020 and 2022 WranglerJLU. When I got the 2022, the 2020 had to go to the shop for body repairs. I swapped the wheels before it went to the shop.

I didn't realize the tire pressure sensors were not compatible. No biggie, just ignore the light.

When I put the wheels back on the perspective Jeeps, the 2022 TPMS was fine but the 2020 had an issue. The passenger front never picked up a signal from the tire pressure sensor. Passenger front always shows dashed out regardless of how the tires are rotated.

To confound the issue further, it had a low tire the other day. The display showed the driver front was low, but it was the passenger rear. I put the spare on passenger rear, and the display showed driver front at 36 psi (the others are 30 psi).

SO, not only does the passenger front always shows dashes regardless of the which tire is there, it seems it's confused as to which tire is where.

I've removed the spare and drove it. I've disconnected the batteries to hopefully reset it, but nothing has fixed it.

I haven't reduced the tire pressure to "wake up the sensor", because I don't think it's one of the sensors. Plus they were all recently reduced the 30 psi (from 38 for wear purposes) and nothing changed.

I'm not sure where to go from here other than the dealership. Any ideas?

Tools that reset your TPMS are fairly expensive. It'd probably be best to take it to a shop. Or maybe your local parts store has one to rent?

Thanks COS. You enjoying the weather?

What's the name of the device I would need to reset it?

When airing down while off-road the blinking tpms light was driving me crazy, I used my J-scan and shut that thing off a long time ago. Perfect!

On another vehicle, I spent $400 on sensors and batteries to stop that confounded tpms light from blinking. 2 weeks later that little SOB started blinking again. I had a tire shop rip all that s**t out and install standard valve stems. The light stays on but at least it's not blinking. I kick the tires, life is good. I'm well aware of the black tape over the light. I also realize most people are not going to do this, I get it.

They're called TPMS reset or diagnostic tools. Note that I have no experience with using one. Just what I've read.

Note that they're not cheap. E.g. https://www.amazon.com/ATEQ-Universal-Diagnostic-OBDII-Module/dp/B0792JTH6R
