Only one TPMS sensor update frequently?

[Jamesmy]

One of 4 TPMS sensors in the tire seems to update more frequently than other 3 sensors according to TESLA mobile app. Is it normal? That tire had a puncture and repaired if that is relevant...

 

[jcanoe]

Maybe because there is a small leak in air pressure (that tire is reading lower than the other tires)

 

[Jamesmy]

Thanks, will update after replacing the tire.

 

[Jamesmy]

Still the same after replacing the tire. Only one wheel updates tire pressure frequently.

You could open a Service Request via the Tesla app. Let us know if Tesla decides to replace the TPMS sensor.

Does the car show all 4 updated together? If it's just the app, there's probably nothing wrong with the vehicle.

 

[Jamesmy]

Only 1 tire pressure is immediately updated upon checking using the app whereas other 3 tires show the tire pressure last updated after driving.

1 tire “a minute ago”
3 tires “12 hours ago”

Its a brand new tire no issue with leaking. The tire valve is good too.

 

[fiehlsport]

Yes, but what does the vehicle itself say? Not the app. Are they in sync?

 

[Jamesmy]

thanks for your reply. The vehicle itself also shows 1 tpms is updated immediately, while 3 others are not. I was worried that the tire was leaking after patching. Since I put a new tire, I am now curious why only one TPMS is immediately updated that happened to be a new tire. Just coincidence?

That is very strange. It's working... so it would be hard to say that one is defective. It just is too much of coincidence that the one that got a patch, is the only sensor reporting.

I'm still not up to speed on how the new software works (Just got my 2nd Tesla a few days ago after a long hiatus) but is there a TPMS reset function available still? That should query all 4 sensors while driving and get everything synced up.

No reset function. The TPMS sensors on the Model Y re-calibrate to their new wheel locations shortly after you rotate the tires.

Gotcha, I'm wondering if changing the wheel configuration will cause the car to scan for fresh pressure data then. Afterwards, just change it back to the actual wheels.

No; All you need to do after rotating the tires is to drive for a time. The TPMS system will automatically orient to the new sensor locations.

I'm not suggesting anything to do with locations - just whatever will get the software to forget the saved pressures and re-scan everything from scratch again.

 

[Jamesmy]

Thanks everyone. For now, I will leave it as is. I am bit concerned about battery drain on that particular TPMS but I will ask a technician when I am due for tire rotations. In any event, I will update if anything changes.

Maybe Tesla Service can initiate a diagnostic reset function but there is nothing the owner can do to reset the TPMS system.

 

[Jamesmy]

Just came back from Tesla Service. Tech says nothing wrong. No TPMS alert in the system. Maybe its just software glitch?

Sometimes it shows updated “6735 yrs ago” then change to “a minute ago”.

I will drive more miles and report back.

 

[Jamesmy]

Yes, LOL.

I'm now perplexed by the Vent button you have in your app... I have never had that on my '22 MYP, and now the Homelink icon is there for me. Even before I had Homelink installed, there was no Vent option. Hmmm....
