TPMS Battery Lifespan

I have a 2018 Tacoma that reads each tire pressure individually. I'm getting tires next week and wondering if I should have them replace the batteries in the TPMS sensors while they're in there, even though I haven't had any trouble yet. The Tacoma doesn't get driven very much, it's sitting at 22k miles currently.

Does anyone know the battery lifespan? I also assume I can replace the battery and not the entire sensor itself, correct?

Just did mine last week. 2017 with 100k on it.

They started acting weird when it was colder earlier this year then once it hit 100F they all died.

 

First, you have to replace the whole sensor, they are a sealed unit.

I have a 2017 Tacoma and they are still working fine.
I have a 2013 Avalon and still have the original sensors.
I have a 2007 Vette and replaced the sensors a few years ago.

They can and do last a long time.

 

My 2013 I traded last fall still had the originals, so decade +. My belief is the colder temps for much of the year help out life a bit, as the main vehicle batteries also go 6 to 8 years for us without issue.

Almost related story - back in the early 90's-ish I got an Armitron basic beater watch. Work, motorcycling, whatever. Since 2016 it's been on my tractor outside in the wildly varying VT temps as it's "clock". It was still running on the original battery, but about 4 years ago I felt guilty and replaced it. Those batteries do last.... (longer than all the schtit AA's we seem to get any more )

 

do they all have the same size/type of battery?

 

Batteries are not replaceable.

If your truck sits a lot, you'll get the long side of that range, so expect the sensors to last until 2027 or so.

 

My TPMS are almost 9 years old with 58K miles on them and working great. I don’t worry about TPMS as I like to manually check the PSI with my gauge. If I get a flashing TPMS light, I will put black electrical tape over the light on the Combo meter and address it when I need new tires. If you feel differently than I do, you might want to get them replaced next week.

 

10 years is a pretty standard rule of thumb.
At that point, replace the sensors with next set of tires.

 

I also prefer not to, but unfortunately some of us live in states that consider their occupants retarded enough to need a non-necessary idiot light to be functional and a clean cabin filter (whatever the f that is) in order to pass "safety" (lol) inspections.

Meanwhile down in the mountains....
