TPMS Sensor Fail: Change One or All?

[music]

Lost signal on a TPMS sensor over the weekend. Searching around, it looks like these things have a service life of ~ 10 years, but obviously... not all last that long. I'm about 6 years in on these, with 61k miles. I didn't think about it when getting new tires, but I should have replaced them all then.

 

Buying the AC delco OEM part online, and having my tire shop install, will run about $50 per tire. There's no cost savings to changing four vs one at a time, but it's irritating to be driving down the road with that warning light going on and off every few minutes as it fails. I'm curious if folks change them all at once (like tires), or one at a time as they go?

My Wife has a bad one on her Cruze. Hasn't worked for a few months now. These things are such a joke, more money to spend to get rid of a stupid light. Anyhow were going to just fix her one, and leave the rest, mainly because were going to try and sell the car. I think there used to be a set of four on EBay for the trucks for around $125. That wasn't to bad of a deal all things considered.

You are not limited to the manufacturers unit, most tire shops will sell aftermarket units. I have a set of Bosh TPMS sensors.

 

The aftermarket units are less expensive, and I would change all four, it is most likely the battery on the unit went bad.

 

You want to purchase 315mgh units.

Thanks for the input guys. I see the AC Delco (OEM) version on Amazon for $35 ea (identical to what dealer sells @ $80 ea), and some no-name brand models on ebay for like $15 ea. There's not much to these things (static pressure sensor, 315 mhz transmitter), but lifespan depends on the battery. I doubt that there is any difference between the Delco and no-name, and they're all "made in china". Hmm...

IMO TPMS is a government nonsense that again takes the ownership/driving issues out of owning a GD car , if a person can't look at their tires a few times a year ,,, then it's a sad world ,

 

Don't get me goin on ABS !!! Lol

I thought that the batteries were dead in my sensors too because of the constant tire light but Discount tire said they were all working fine on my 2008 Silverado..I also did the reset on each one and they worked fine. Still dont know why the light is on.

I agree in some aspects but if your driving along the alert is great. Got a nail in my camaro no clue as I was driving along no symptoms alert came on I flipped over and seen which tire was low (rear drivers side) stopped and checked it and sure enough it was low.
