TPMS not working but not sender in tire

[Mac]

Recently on my '20 JT the TPMS stopped working on the driver's side, thought it might be senders in the wheels but when I X rotated the tires the TPMS problem didn't follow the wheels, the senders are reading fine on the passenger side still. Anyone seen this problem, assume there is some type of module at each wheel that reads the signal assuming something failed either for the bus that feeds both of them or they both failed. The front tire stopped reading first and then a month or so later the rear driver's stopped reading also. Anyone seen this issue? Thanks.

I have a Grand Cherokee that had a blank readout for one wheel. I rotated as you did and the problem didn't move. I had it scanned at a tire shop. They said the tpms module was fine and I needed a new sensor. I had a new OEM sensor with me and they installed it. The bill was $24. They told me they have seen it many times, that a bad sensor would not be able to relocate position. Therefore nothing moves.

Find a tire shop or someone with a TPMS scan tool and test the sensor in each wheel. If all the sensors show good, with good battery life, then it will have to go to the dealer for a receiver check. If it is a sensor, probably best to have them all replaced now.

Do you have remote start?
If so, does it still work from a distance?

That’s wild. That’s seems like a correlation/causation that would take most ppl a long time to put together. What’s the test for that remote start antenna?

Yes, remote start is working fine, use it daily, I think it is about 100’, not sure how far it should work from. thanks for the info anyway.

I think you would see all tpms blank if the above tsb was the issue. One corrupted sensor will do what you are seeing. Scan tool saw the radio ID of the bad sensor it also saw the battery level. All other data was lost at the bad sensor on mine. Since the car could not assign the bad sensor a new location, the auto calibrate did not happen when you rotated your tires.

Your best advice is going to a tire shop and let them scan it. I bet they would be cheaper than a dealer and no appointment necessary.

No, it actually starts out with the fronts - those farthest away from the antenna. If it's bad enough, then it will impact all.
Note that it says "the most susceptible are............ and shows the FRONTs on a JT.
So it can impact all, or just the front because it's a range issue. That's why I asked if the remote start worked. Of course, I didn't account for the model year changes and so on because the TPMS module was moved in the middle of the 21 model year.

He really needs to do what you and another post said - get to a shop with a proper scan tool that will show battery level and if each sensor is working.
One sensor throwing a hissy-fit can mess things up.

The same antenna was used for the TPMS as the remote start function.
The first TPMS to fall off in event of an antenna issue is the front, assume because they are the farthest away from that antenna/module.

In this case, It was likely just a wild toss of the dart that missed the bullseye for this specific owner/Jeep but it's still a valid thing - if remote start is iffy, if you have to get close and gee, one of the front tires isn't showing up, could be a connection (depending on year I'd bet although the service document doesn't specify)

The tire shop told asked me if all were out or just one. He said if all were out there was an update that he could do. He did not say the update was for but it did relate to the key fob. A new battery for the fob was never mentioned.

If it was one sensor blank, he said it is most likely a corrupt sensor. He also mentioned this to be common along all makes and not Just Chrysler. He did not specify JT, JK, etc. Tpm gets locked up with missing info. Deleting and adding a new radio ID usually takes care of it. And that can be done before installing the new sensor to verify it works.

Makes sense since Chrysler/FCA buys those sensors, they don't make them.

Had the sensors scanned at Town Fair Tire, they said the two sensors that initially stopped working were bad. They thought it was unusual the sensors that were still working appeared on the wrong side. I have ordered new sensors and will replace the two that are bad.

I have one bad sensor that’s worked once in the last 15,000 miles. It went out for about 10k, then mysteriously came back for half an hour, and it’s been out for the last 5k miles. When I rotated my tires it took 8 days and over 300 miles for it to swap spots on my dash. The sensor had almost 4k miles on it when it went bad at only 6 months of ownership.

Moral of the story is these sensors suck.

If two shit the bed, I would imagine the other two are not far behind. I would suggest having all 4 changed just to re-baseline everything.
