New R1T TPMS Issue

[squinn61853]

Coming home today from running errands, I got a "TPMS failure. Service immediately." (or something like that) message on the drivers display, and when I switched to the tpms view on the diver display, the two front sensors were out (rear both working, at 46). I let it sleep several hours and checked, and same thing. I did a soft reset, which I didn't expect to help, and it didn't, then did a hard reset, which I did think would help, but no such luck.

It's weird (too me) that both front sensors would go out together - I assumed that tpms sensors are independent.

Any thoughts or experience with anything like this? I haven't made a ticket yet as I'm hoping this is a simple fix.

BTW, R1T Tri, picked up week before Thanksgiving. Absolutely loving it - I'm just under 1k miles (so far).

Thanks...

No real idea... but could be a faulty tpms sensor module. It would be weird for two sensors to go bad at the same time. At least I'm the Gen 1, it is located in the upper C-pillar on the drivers side. Time to open a ticket.

I had repeated issues with the TPMS where the entire system would be unavailable randomly (usually after a longer period of driving). Service replaced the TPMS, tried to relate it to other computing components that had to get replaced, but it kept coming back. The final fix was an emi filter on the cables for the system. The way it was explained to me was that on paper and in initial designs, everything works (of course). In reality the buildup of individual tolerances of components/positioning was enough to cause issues in certain circumstances.

I would ask them to take a look at that if it ends up not being the individual sensors.

Stupid question, but the truck should be fine for driving, correct? I.e., there are no weird, non-obvious dependencies between the tpms and some other system(s).

As long as there isn't an actual low pressure condition in the tires there is no problem driving. If you don't have a handheld pressure gauge I would recommend grabbing one (always good to have).

Alternately, you can use the onboard compressor to ensure they are at pressure (just make sure to read the directions or the auto-off function can cause confusion).

Thank you!

Second this, get yourself a handheld pressure gauge and check it. Recommend verifying 48psi manually at least every few months, as the seasons change. TPMS sensors are usually off in either direction.
