TPMS failures
We hear constantly about the wonders of TPMS systems . Anyone ever have a failure ?

Why the heck does the monitor scan though the sensors every few seconds AND it appears to give an instant alarm if it looses the signal...
That is the way our TST system is designed/manufactured...and that is what some of us are not happy about:
If our monitor loses a sensor's signal, the reading displayed for that sensor is from the monitor's stored memory.
The monitor will continue to give a phantom/memory reading for up to an hour while it tries to "find" the lost sensor signal. Everything will look normal on the monitor and you won't get any warning of a dropped sensor signal.
After that hour or so, the monitor is programmed to give up waiting for the lost sensor signal to come back.
After that hour the memory readings stop, you hear a beep and the reading for that sensor goes blank on the monitor.
Like you said, a TPMS is an aid, not a fix.
It isn't perfectly 100 percent reliable.
