2018 Accord TPMS failure message, Why?

[fdcg27]

The day before we left on a three week trip, I saw an odd message on the dash display of the Accord.
It read "Tire Pressure Monitor System Problem.
Check Tire Pressure.
See Your Dealer".

While not really happy I figured that it would get us to the airport and then home, which it did.
Re-calibration causes this message to go away only briefly.
Anyone have any idea what the cause might be and how I can remedy it without the "See Your Dealer" part?

Does this Honda system use batteries in their TPMS sensors?
Have they been changed?

Did you check the pressure?

Does that Accord have direct or indirect TPMS? Honda used indirect on the previous gen 2013-17, but Honda eventually went back to direct with their newest models. I don't know what they did for 2018 TPMS.

No, the TPMS works off of the wheel speed sensors.

Set the tire pressure to cold spec, select calibration three times in a row.

I did exactly this a few days back and it fixed the message.
Figured it was worth a try.
