Keep the TPMS?
- Thread starter GC3
- Start date
If the TPMS in the take-offs are the OEM Toyota sensors I’d keep those for sure. People here are reporting wildly varying experiences getting new TPMS sensors to work with these vehicles. I’m sensing (pun intended) that the system is sensitive to the type or quality of the sensor.
My experience has been on the frustrating side; I have not been able to get my aftermarket sensors to recognize at all.

Hmmm, just be careful of the valve stem assembly that the sensor attaches to. The mounting screw is self tapping and only designed for single use. Not sure if they will disassemble or just pull the whole thing out when removing from rim.
* But to answer your specific question, 100% yes, keep the OEM sensors. Even if you need to purchase replacement valve assemblies.

Thanks for the heads up!
Unfortunately, I have to wait until Wednesday to get my new tires. I was all checked in, sat down for less than 10 minutes and they said they could only find 3/4 of my tires. ill post an update once installed to see what they say about the stems.
Definitely keep the OEM TPMS. I have two sets of wheels (stock 20" and a full set of Method 703s), both with a set of Toyota TPMS. I had no issues connecting the OEM TPMS to my LC. My cost for the OEM sensors was about the same as the cost of an aftermarket sensor supplied by the tire shop. You can find cheaper TPMS online, but compatibility is always a potential issue. If you do look online, the OEM sensor is a Pacific Technology Sensor (see pic below.)
One risk you take is if you try to swap over the TPMS, the 20” wheels and tires will then have scrap value if you try to sell them. If you leave the TPMS in you can always use them later and might be able to sell them for a few bucks.

FYI the tires can still hold air without the TPMS. The vehicle is still functional without them as well. I ran the lc for 6 months this winter without TPMs. Mechanics will still inspect a vehicle that doesn’t have the TPMs. It’s just a nanny system for… well…
TPMS has been mandated by the federal law since about 2008, and many states that inspect vehicles will impose penalties for malfunctioning or missing TPMS. There could also be significant legal liability for driving vehicles without TPMS in case of an accident.
Maybe Im not following? so you're saying that if I remove the factory TPMS sensor you cant reinstall a factory TPMS sensor (or aftermarket)? don't these have little batteries in them and die after a while?
The PSI police eh? Is that what your gynecologist told you?
There are 2 parts to the whole assembly. The tpms sensor itself and the valve stem. Here is the part number for just the valve stem (one time use part).
Valve - Toyota (90942-05051)
The tire shop will/should remove the sensor and install on a new set of valves.
Where are you at? Discount Tire pulled the OEM TPMS sensor out of my spare and put it in the new spare tire/wheel combo that I bought from them and they did it for free (did this today in fact). Im in DFW.
Cool that makes sense, I was just very confused by @D-mac's comment about the stock wheels being scrap if you remove the TPMS. Most take off's around me do no have TPMS. I sold my 3g taco stock wheels without TPMS for 400$ back in the day.
In my opinion getting $300-400 for 5 almost new 20” wheels and tires that were a $1200 option isn’t a lot, but I will agree it’s a lot more than nothing.
I asked the lead tech about this and he confirmed this. They had no issues replacing the stems to the OEM sensors and onto my new wheels. FWIW the 10$ fee for switching the sensors over includes the new stem at discount tire.
Update - the aftermarket TPMS in my new wheels started working a few days ago. I’d been trying to wake them up for about 6 weeks, had performed the procure no less than eight times and had driven probably 800 miles. I have no idea what caused them to work, but here we are.
