Ugh, this is why I prefer to do stuff on my own and even still manage to screw it up from time to time. I don’t need any help messing stuff up lol

I had to pony up for a tpms programmer from Autel ts508wf. It’s worked for me with Toyota tpms sensors. I’m pretty sure it works with the majority of aftermarket sensors too. Check it out if you want to go another direction with your solution.

I can’t imagine I can’t fix this with the Schrader ST-1 programmer I already have…. At least I hope I don’t need a second TPMS programmer.

I tried (and failed) with the first tpms programmer I bought. Good luck regardless.

The Carista app with the paid subscription will do it. The ODB FUSION app doesn’t have it. I have both and am hoping OBD FUSION will get an update to have this function so I can cut out Carista.
20mins is more then enough time for the sensors to register, any chance one of the new sensors is bad?

They aren’t new, I’ve had them registered and working fine for 20k miles. It’s not until today when I relearned them that they quit showing on the dash. I had to putz around the menus to remember what exactly I needed to do and I must have not done something correct as they were displaying before I relearned them just in the previous locations before I rotated.

I’ll have time to fiddle with it tomorrow.

With the Carista app, can you remove them and start over?
 
I just checked the manual and it could take up to 1 hour to start work after resetting the TPMS… maybe I’ll take another drive.

It definitely takes a while for the TPMS stuff to reset. Only reason I know is I have the spare tire off and after I reset the warning light, I can drive a few times before it throws the error again about the missing tire.

that’s interesting….they should relearn shortly after driving unless a sensor went dead. I’d try and reprogram the IDs through the Carista app. Its instantaneous when using it, the system will recognize them and displays the PSI right away.

On Carista now and they are all programmed on there correctly and the ID’s all match what’s on the Schrader programming tool, still nothing showing on the dash.

Since the manual states it could take up to one hour I will make another 20-30 min drive and see what happens. Otherwise, I’m not sure what I should do next. Carista won’t let me remove the sensors, only change their ID’s.
 
Last time I aired down/up I had hashes on all the TPMS sensors. I figured it was due to low battery on one of them. Tried to reset it myself and no dice. Went to discount tire and they used their wireless tool which sounds like yours. It learned each sensor ID then he plugged into my OBD2 port and uploaded the info to the ecu. Went driving for about half an hour before they came back. Been solid for a few weeks since.

Yeah this is the same process I am doing…. Maybe I’m just not giving it enough time.

I can’t get them to reprogram on Carista, it’s saying the ID’s can be the same as another sensor so moving them to different locations is a no go.

Im debating on creating a new set to program then just add these back…. Idk.

Updating this post.

I decided to try to just change one of the letters in the sensors and save it then correct them… Carista won’t let me do that, I’m getting a communication error…

At this point I may just reprogram with the Schrader tool and just see what happens. I can still see all the TPMS data on my fusion app so it’s not like I don’t have access. The tire PSI frame is what I always have in that area on the gauge cluster so there will be some annoyance as I guess I’ll just stick the inaccurate and redundant MPH there instead.

It's incredible to read the hurdles one has to jump just to get a tire sensor to show up. Also dumb that just one set can be stored. Lastly to take a hour to register sounds like it's using an RS-232 connection...:arghh:

Did not follow all of this. Could the battery be low/going out on your sensors in the wheels?

I don’t think it’s batteries as these were new as of August 2024 and the Schrader programming tool lists all batteries as “OK”.

I was able to solve the TPMS issue. I remembered that I had one of those Launch tablet things that does OBD stuff so I got it out and stumbled through its terrible menu until I found the TPMS section. There I went through the TPMS ID’s to make sure they were all correct… they were correct but the rears were in the wrong place so I changed that and wrote all that to the ECU. Test drive was next and the air pressures were showing and all in their correct locations before I was out of the driveway.

Thanks for the sounding boards, everyone!

Glad you got it sorted out...but I am confused. If the car knows where each TMPS sensor is, why do we need to program this crap..lol..
I am just not understanding why Toyota is making this so complicated.
 
Launch tool FTW. Menu is terrible but it is so useful.
 
The SEARCH function is good though. But it does help if you're fluent in Mandarin.
