TPMS Sensor Longevity?

[bigchick]

we have the Tire Tracker TPMS system for out 5th wheel. it has four of the sensors that screw onto the valve stems. the original sensors are about 7 years old. i have had issues with a couple of sensors over the last two years so i bought 2 new replacement sensors. on our last trip earlier this week i had two sensors that were not reporting. all four sensors had new batteries installed in them. what i do not know is if the two sensors that failed to report were still original sensors or not. when i readied the trailer for the trip i went through the process of screwing the sensors onto the stems so the monitor could know which position they were in and all sensors were seen by the monitor. yet when we were actually towing two of them failed to send a signal. or put better, the monitor failed to receive a signal from two of the sensors.

so my question is if anybody knows if these sensors have a life expectancy? is it normal for them to fail after a period of time? what time period? even though we have the Tire Tracker system any experiences you have from sensors for other systems would be appreciated.

thanks

Tiretracker TPMS with 7 year life is impressive!!. No problems on our fifth wheel trailer, tow vehicle sensors, etc. after nearly 3 years, except for occasional battery replacement. Have you checked with Matt with Tiretraker at matthew@tiretraker.com?

Try replacing batteries. We have EEZ TPMS (may be different re battery access) & we remove the sensors when storing motorhome outside in cold winters.
