Question on TPMS reliability, please advise!!

DurangoUnchained · Sep 17, 2018

Is it possible that one of the tire pressure monitors can temporarily throw off a faulty reading? 3 of my tires were spot on, but the left rear was showing 26 psi. (If it matters, I topped them all off no more than 3 weeks ago) This was at approximately 5:30 a.m. I stopped to put air in the one reading low, and it took a significantly shorter time to top it off, than when I did it a few weeks ago, and they weren't as low as this one. I just went out to the parking lot at work at 2:30p.m., and checked it, and the TPMS said it's exactly where it's supposed to be.

So can these things be temporarily screwy?

Well, they have a battery which eventually wears out, could be getting flaky on you.

Correct. Usually a 5-7 year life span in my personal experience with TPMS on various Chrysler vehicles.

Ok, thanks fellas. A battery never even crossed my mind. I know they get out of whack when the temperatures first start getting cold, but wasn't sure about any other issues. Appreciate the responses.

You can buy virtually the same sensor the Dealer sells for about 1/3 the price at RockAuto. Avoid the Dorman brand like the plague!

The Denso sensor here should be an exact replacement for OEM and they manufacture for Chrysler. $39.79 each.

And don't get sucked into a tire shop offering one of their own shop brand sensors for $125-150! Only issue with supplying your own sensor nowadays is some tire shops won't install them claiming "Liability" or other BS. Shop around and find a tire shop that will install the sensor you bring them.

Thanks for this info. I was just checking in here today to find something on the TPMS as one sensor is no longer communicating. That tire and another were reading low the other day and I filled them all to the same reading but that tire reading just kept flashing for a few days then went blank " -- " and now displays system error.

No Problem. Having went through this ordeal on a couple of other Chrysler vehicles, I figured I'd help others out. Chrysler parts have been climbing way through the roof in the last 4 years or so. TPMS sensors are one of a handful of parts you can get that are vitually identical to the dealer parts and cost 1/4-1/3 of Stealership markups.
