Tire Pressure Sensor warning?

[TBill]

Funny, my right rear tire TPS gave me a failure notice yesterday. The warning stoped about half way through my 1.45 hr. drive then came back. When I started my return trip, no failure warning all the way back. I think based upon the responses to this it's just a matter of time before it fails again.

TBill, most likely the battery is going out. They will tend to produce more voltage when warm, so once you get going and the tire/wheel gets hotter the warning goes away.

Lifespan depends on miles driven. They go into sleep mode when wheels aren't spinning. When I replaced them on my '14, they were working fine still at 8 years old, just replaced them because my tires were aging out so did it while the shop had the tires off, figured the originals wouldn't last as long as the new set of tires will.

The cost can be mitigated if you buy the sensors yourself from Rock Auto or elsewhere, for about $35 each, then a place like Walmart will mount/balance the tires for $10 to $19 each, might be a couple bucks to sync them (or DIY, don't they now self-sync after driving a while?).

Yeah so another one went out today. The third is about to go out. One is new on one side and the other is still working. Maybe they won't charge me a $100 deductible each time if I replace more than one at a time.

UPDATE: This week the other 3 sensors failed and my dealer replaced them for $100 deductible. So now I have 4 new sensors for $200.

With your experience would your recommend waiting after the first one fails and save $100.00?

Yes but I've had such bad luck with tires last 10 or so years that I didn't want to go several months without a sensor. Advisors said they should last 7-10 years but they were wrong. 5.5 years max for me! If you want to wait 3 or more months for all 4 to fail, you will save some money!

Yep, everyone with 2020 Explorers is starting to report dead sensors. My Explorer was built in 2019, so mine also lasted 5.5 years. I have posted before, if you guys have one or two sensors failing, just wait and replace them all at the same time. They are all going to fail within short time of each other.

Yeah, I'll wait for my next 3 to go.

Stupid me... I recently replaced all the tires on my 2020 ST. Should have replaced the pressure sensors at the same time. Oh well.

 

[TBill]

You folks are correct, I am having intermittent failure of one of my sensors now, thinking about replacing them all.

Me too, new tires on April 15 but the sensors went out a month later, all 3 at once. The first one went out back in February. Warranty won't cover them until they fail not before.

Had the right rear one completely fail after some intermittent failures, local tire shop did it for $79.95 + $10.00 labor, dealer wanted around $250. The local shop scanned the other three wheels for battery life, they were OK, not low.

I had one replaced again today by my dealer for no charge, after it failed in less than 3 months. It could not be trained so they replaced it. The other 3 were replaced a few weeks ago. I've paid $200 in deductibles under ESP.

My second one just went. Waiting for the other two.

I have had 2 replaced last week, 1 replaced last hear and my 4th just started to go out. Fortunately every time, I've waited for a different issue to pay the same $50 deductible.

My trans is currently being rebuilt with 112k on it so my 4th one is being replaced at the same time.
