TPMS Failure Mode

[wjburken]

Lots of posts here on TPMS sensors, but can’t find one that deals with my issue, I think.

Wife’s 2013 Yukon says the front PS tire is at 28 psi. When I put two different analog pressure gauges, it reads 40 psi. The other three read correctly and respond. Would this be a bad battery? Normally I get no reading when a battery goes out, not a wrong reading.

Sub'd.

I replaced my TPMS’ a couple years ago. It was winter and they just started dropping out. I relearned a few of them and they lasted a few more months then finally when trying the relearn, no response. I haven’t had any rogue reporters.

Not sure I’ve heard of one reading low. What happens when you increase or decrease pressure? Might try deleting it and doing a relearn.

Receiver side of the system? Spitballing here FYI

it's a bad or low battery sensor, just replace it. had it happen before

Either way, you're gonna have to break the tire bead to access it. If I'm that far in, I'm replacing it. Unless they've been replaced, the others are just as aged and are likely to start dropping dead soon.

Everything seems to be working fine now. Hope it lasts so I can deal with it when it’s warmer out.

Maybe the battery is coming to an end and the cold weather is causing the cold battery glitches?

Maybe it had a bit of poop in it...
