Glad to read all is well with you and your system, KirbyBear.
I'm pretty sure that the system is supposed to respond to an instant/massive pressure loss. This is what we simulate when we take a sensor off a tire. The monitor gets a reading from the sensor that the pressure is suddenly gone and we should get an alert.
In a strange coincidence: We got home from running errands in the Exploder today and noticed a horrible something's-burning-type smell. We traced it to our back, passenger side wheel. IR showed 136f after sitting about 10 minutes. After rebooting the TPMS monitor (which we shut off when we parked) it showed a similar temp after the sensor sync'd up.
No alarm though. I'll look into the settings on that monitor when I have more time.
Does anyone know what the default is supposed to be temp-wise?
