2018 Ford Explorer -TPMS mystery

The winter wheels I rotate in during winter have the same TPMS sensors I had in my 2015 Explorer. However, they do not work with my 2018 Explorer. A Tires Plus tech went through the reset protocol and things appeared to check out. Nonetheless, the tire pressure display does not recognize the sensors. I’m told they should. What don’t I know?

You may consider asking your friendly local Ford service department. Or, if the TPMS does not affect any other systems, ignore the light, periodically checking your tire pressures, until you change back to your summer tire/wheels.
