Hey guys,

I notice that when putting on my winter tires two of them (on my oem 18 honda rims) have virtually no air pressure in them. I filled them up and sprayed soapy water everywhere and noticed the sensors seemed to be bubbling at the valve.

Given these are the original and they're secured with a nut. Are they serviceable where I can clean them and reseal them or do I have to replace them?

Only reason I suggest salt/brine is that they're metal on metal and salt brine water has a way of sneaking in places like that usually.

I think the seals can be replaced. Locally our National Tire and Battery (NTB) offers a rebuild kit just for this reason that's the components holding in the TPMS. And of course they can replace the TPMS units for a heck of a lot less than the dealership. I had two replaced on my '07 Avalon and I think they were $35-40 a piece? And the other two have the original batteries still, and continue to work. Who knew!

Someone else correct me if I'm wrong here but I think this can be done...

had the same problem... the rims corrode on the inside where the seal between the valve goes through the hole.

the corrosion causes the paint to flake off from the corroded aluminum dust.

Standard makes a TPMS repair kit its like 10 bux for all 4.

you dont need to take the tires off the rims to repair, just break the bead near the valve, wedge something between the tire and the rim, remove the TPMS sensor, clean the corrosion around the hole, install the new rubber ring and stem cap.

did mine a couple years ago, and still good.

This sounds like a standard fix at a tire shop too (if you live in a place where that kind of thing happens). Would likely cost the 'tire patch' price plus parts. Probably <$100 OTD - maybe less.

Would be a good time to re-balance the wheels too, if it hasn't been done in a while.

Also, it is normal to lose ~1 psi / month with tires without any actual leaks..

+1 for yes, there is a seal kit to repair them. Being that the rims are '18 and the van is a '12, how old are the sensors? If they are only a couple of years old then repair them and drive one. If they are 8 years old you may want to consider changing them because the batteries may be so near the end of their life that you can one time and have a long term fix to both issues. Ordering OEM sensors from an online dealer (no Amazon or Ebay due to high risk of counterfeit) is typically the best bang for the buck as many tire stores get close to $100 per sensor for aftermarkets.

Yes the seal is sold separately as wheel as the nut and washer. No need to replace the sensor unless it's not working. Have a tire shop thoroughly clean the mating surfaces.

mine are 9 year old originals, probably due any day now, but 10 bux was way cheaper than replacing and reprogramming all of them.

the one tool I do not have.

Next time you replace the tires and the sensors don’t seem to be failing, change all em out. I just changed my tires in summer and thought the sensors were fine...now all of them failed lol they lasted exactly 10 years (technically 11 years since my car was made in August of 09)

One thing I have observed is mileage seems to be a factor as well. On my '07 the 10 year mark was about when they failed and at that point the van had around 170K on it. But on my MILs '09 Accord the sensors are still original and working fine. The kicker is her car only has 19K miles on it. TPMS sensors do go into "sleep" mode when the car isn't moving, so if you see an older low mileage car that still has original sensors that still work that's why.

My van has the same mileage. You're right.

Just adding a big Yes to list of those that say that they are serviceable. My indy mechanic just serviced one on SWMBO's CR-V. He cleaned the rim at the same time and her slow leak has gone away.
