OEM TPMS not being identified after changing wheels

[QNH_250]

I swapped out my wheels earlier this week. I retained the factory TPMS units, but had them attached to new Apex Valves. I made sure the garage maintained the same wheel positions. My expectation was that the TPMS would not be impacted it but turns out I was wrong... no pressures showing upon leaving the garage for any of the wheels, and car threw a TPMS malfunction error after 15 mins or so.

I followed the manual procedure for tire rotation, nothing. I then followed the procedure for installing a new tire set hoping it would force re-identification, also nothing, even after driving 100s of kms. The yellow low pressure light is solid (indicating it has detected the units) but it just stays stuck at a message that it is setting tire positions.

Anyone face this issue after changing wheels or valves? And any advice on how I can fix?

Reading the APEX directions, their valve requires an adapter to use Toyota TPMS (and my LC250 uses one-piece sensors). If you can use the TPMS correctly with a normal tire valve, then you know what the problem is.

I am aware of the adapters and I don't think that's it. I watched the install and the technician mounted the TPMS with a single screw, as in the image below. Could be that we get different sensors for the GCC spec models to what you guys get in the US. If all else fails I'll take apart the spare to check.

Not sure about any of this, I’ve never used that product but when I swapped out my wheels I had after market TPMS sensors that took a good week for the rig to recognize. I had honestly given up on them, and then suddenly they worked and haven’t had an issue since.

Just to close on this for the benefit of anyone considering Apex valves - the LC250 OEM TPMS sensors are compatible without an adapter. The adapter is only relevant for older Toyota TPMS sensors. See picture below.

Turns out the reason my system malfunctioned was because the garage damaged one of my sensors during the wheel install It's been replaced with an aftermarket one and everything is now working perfectly. Garage was able to program everything using an OBD tool.

The valves have been great, and I can recommend them without hesitation as a quality of life mod if you mainly drive on sand/otherwise deflate frequently. These things are insane. They take me from 38 psi to 10 psi in 12 seconds flat.
