TPMS Fault - This is a weird one...

[JWest412]

Please help!

I just bought a 2016 Model X. It came with 20” stock wheels. I bought 22” wheels from someone on this forum. They didn’t come with sensors. I found some for $80 for all 4, they promised no issues...

I had the tires mounted with these sensors, and after 5-10 mins of driving they show tire pressures, but it says there is a fault.

I tried troubleshooting. Let air out, put it back in (found this on another post). I reset everything in the wheel settings, no change in the fault.

I had the vehicle in Tesla Service today. I bought new Tesla sensors and had them put in. The fault is still there, they have no idea what to do! And now, it’s worse. I have no PSI numbers with the $400 worth of Tesla sensors. It shows no reading at all AND a fault.

What am I missing? Please help!!

Failing MCU1 eMMC can cause a *wide* variety of symptoms?

Just spitballing here..

Ha. Worth a shot.

Can I just compliment you on the titanium color and chrome delete? Very snazzy..

Haha! Thank you so much! I love the way it turned out. Everyone always tells me how much they love it, then they say that they’ve never seen one in that color. It’s cool to have something different!

Hi @JWest412 ,

You may need a new TPMS ECU...
It's Tesla part 1034601-00-? ? Whatever is current.

Last I heard they are not terribly expensive...

Good luck,

Shawn

Hi @JWest412 and @ngng ,

I think you are misunderstanding the part number listed.
The ECU 433 mhz receivercomputer that runs the system is 1034601-00-? Last I looked they were $25 from Tesla
and about $125 from eBay. There is only one needed per car...

As luck would have it the TPMS Sensors for each wheel is only one part number different.
1034602-00-?. They are priced higher and of course you need at least 4 of them...
Maybe 8 if you run snow tires and summer tires...

Good luck, I hope you are able to fix it.
It is a most annoying problem with these wonderful cars...

Well as it turns out, when I went back in, the SC said that they installed the wrong TPMS sensors. They installed the right ones and it’s all good! But now that I read these posts, they probably tried to install the Bluetooth ones and not the MHz ones. I should be due some money back, right? I did think it was strange that they cleared all of my Bluetooth devices during my first visit.
