TPMS : 2 sensors quit reporting at same time
I recently inflated my tires from 26 psi (been letting it go for awhile) up to 32 psi (my preferred pressure). A day later, the RF set off the monitor, and the LF followed within hours. A few days later, both still read nothing, but the rear sensors are still OK. Just a coincidence ? or is something going wrong with the read-out? I have eight wheels, both sets from 2009 panels, so I can't tell which wheels have received new sensors (I replaced two, 3 and 4 years ago). Seems odd that two would fail within a coupla hours of each other, doesn't it?

They both show dashes. If it is just the sensors, I might not replace them, since they're just a pain (and expense). Does the TPMS have to be functioning to pass the safety inspection, coming next month? I'm spending cubic dollars on a new home project right now, and I don't need more $ outlay, at this time.

If it was the RCDLR none would be working. There are DTCs for the TPMS, they just don't cause CEL (because they are not related to emissions).
You need to know what you are doing with the code reader to get them. Each has a 2 digit hex number after it that tells the exact reason.

Thanks. I have enough on my plate (demo and replace house) for now, without replacing faulty sensors. I wish they weren't on my panel or my wife's Cobalt...they are just another unnecessary piece to fail, and need to be replaced too often for me (like the headlamp bulbs, until I took out the running light fuse on the panel...makes my bulbs last 4 times as long). I'll check the codes when I remember to, but since it isn't an inspection issue, then it'll be on a back burner.

7 years; that's too often? How often do you change a watch battery?
So, now you get 12 years out of headlight bulbs? Hint: get the cheapest bulbs; the cooler they are the longer they last. My OE bulbs lasted 3-4 years, replaced with expensive "bright white" bulbs that lasted 6 months, back to the cheap "yellow" bulbs never did blow.
And got 2 class-action checks from Sylvania for their false advertising life estimates.

slight exaggeration of timescale
