Does anyone know the size of the battery for the tire pressure sensors inside the wheels? I'd like to buy them ahead of time to swap in new batteries when I switch out my wheels.

I'm not 100% sure, but I believe these sensors are supposed to last a minimum of 6-8 years.

Well that truly sucks. Not only will we have to buy new sensors when the battery dies in the old ones, but we will also have to pay the dealership to link the new sensors up to the PCMs in our 4Runners.
If that's the case, I'll probably just pull apart my instrument cluster and remove the low tire pressure light.

Someone posted that they read in the service manual that the batteries have a 5-year service life.

Ouch!! 5 years and I have to replace 5 stems at $100+ each and have the stealer reprogram? Sounds like very expensive maintenance to me. Probably looking at $700 just to replace the stems!

Yeah, and don't forget the additional costs of dismounting/remounting the tire and rebalancing. Disabling the dash light sounds like a better option to me, especially considering that I like to check my tire pressure once a month.

Just wanted to let everyone know that I read the Toyota TSB on the tire pressure sensors, and it says that the lithium batteries in the pressure sensors should last about 10 years. That's not too bad....
I'm not too sure where the 5 year estimate came from, but what I read came directly from a Toyota TSB.

Interesting... Toyota is publishing conflicting information.
The 5 years came from the Factory Service Manual.
The 10 years is mentioned in PG004-06 (posted in this thread).
I wonder if the 10 years is just optimistic thinking, possibly caused by negative reaction to 5 years. The first ones came out around model year 2003, so I guess we'll find out soon.

Yeah, I haven't heard anyone complaining that the tire sensors stopped working because the battery died yet. But if I'm not mistaken, the '03 models didn't have tire pressure sensors. I'm pretty sure the '04 models were the first to get them.

My 2013 RR TPMS battery lasted 5 years, wish it was 10 years. A dealer does not have to do this work, part without labor at a Tire Discounter is $ 76.00. Yes it can add up and be expensive.

Nice tread revival for your first post! My 2004 has the original TPMS batteries... "they don't make em like they used to"...
Welcome to the forum. :tea:
They should put a USB port next to the valve stem so we can recharge them. Or add wireless charging that gives it power every time the wheel rotates. Or energy scavenging that makes power from movement of the wheel. Or a small solar cell.
At least one of the sensors in my 2007 just died, oddly coinciding with the pressure dropping below 28PSI (the threshold to trigger the light).

i still have the original for my 2005 4runner. its 12 years and counting.

My OEM sensors lasted 12 years as well
My OEM sensors from my 2004 lasted until now. I think 4 of the 5 are still working! 15 years.
I've seen some youtube videos of folks replacing the batteries, some soldering but it would be totally worth it to not have to replace the whole thing and then pay to get it paired to the vehicle.
I'd love to just remove one of the sensors from being paired, and only keep 4 on my tires that are on the ground and leave the spare without one.
