Traker sensor on one wheel would not work then next day worked fine,than different wheel didn't work
If batteries are pushing a year, that might be it. If those tires were on toad/trailer, distance/inteference could be an issue ...do you have the repeater? I've had one "go missing signal" a few times, but if I went to that wheel and unscrewed the sensor, it immediately alarmed so it was definately working! The sensors supossedly go into sleep mode when parked, and wake up with movement ....
