TPMS Sensor Won't Connect

Did a tire rotation and ever since the TPMS light has been flashing on startup. I scanned the sensors with the

$219 Autel MaxiTPMS TS501 PRO, 2025 TPMS Programming Tool Same as TS508, Up of TS501 TS408S, Relearn Activate 99% TPMS Sensors, Program Autel MX-Sensor 315/433MHz, TPMS Reset & Diagnostics, Lifetime Update

Autel MaxiTPMS TS501, 3 of the tires scan immediately and one won't (tried moving the tool around, etc.). I guess the sensor is dead and there's nothing else to try but replacing it?

Truck is only 3 years old (2022 OR), so seems weird the sensor would be dead already?

 

Did you reset the TPMS using the button under the steering wheel?

 

Yup, did this after I rotated the tires. Now the tire pressure light immediately starts flashing then goes solid, hitting the reset button doesn't seem to do anything (light stays solid).

 

Yep, the battery in the 4th is bad.
Nope.

 

He scanned the 4 sensors and one didn't scan; bad battery possibly. The TPMS button works when all 4 sensors are good and allows the truck to recheck the positions and pressures of all 4 working sensors.

 

How cold is it there? Our 2015 Corolla did this (flash, then solid) on a really cold day, but it turned back off. Those are nearly 10 years old, though, so one of the batteries is probably getting too weak. Sounds like one just has a dead battery.

 

Not especially cold (probably 40s or 50s during the day), and it's been happening consistently. I feel like the rotation has something to do with it, TPMS was working fine before it. Guess I gotta replace the sensor.

 

Wouldn’t it still be covered by warranty?

 

It has ~66k miles, so I think out of warranty

 

Don’t hurt to try IMHO.

 

Yeah, pretty sure it would fall in the 3 year / 36k mile basic warranty so I'd be well out of it. Calling the dealer can't hurt I guess.

LesSchwab quoted me about $60 to replace it, which seems pretty reasonable given that Toyota lists the MSRP on the sensor at $108: https://autoparts.toyota.com/products/product/valve-sub-assy-tire-pressure-monitor-4260702050.

 

One bad sensor means none of them will report.

 

Good luck on your problem solving.
My TPMS batteries lasted close to 10 yrs, damn mandate item is been more of a mystery to most.

 

Took it to Les Schwab. They said all the sensors were fine and reprogrammed them for $25. Now the pressure light is off, but pressures still show "---" after driving for 30min (stop and go traffic, so not actually that much distance). I'm pretty sure the light will come back on at some point.

I guess they must have some other scan tool that can read the sensors? My Autel tool instantly reads 3 of them, can't read the 4th no matter what I do, so one of them is clearly broken or different.
