TPMS issue
Hello, to be honest, I never see the tires pressure on the dash, I use a good tire pressure meter. Last night I was looking at the TPMS sensors of the car on the dash, and found out that the rear ones are marking 0psi, and the front ones were correct, what can this be??? Bad TPMS or re-programming the same one?? Any suggestion??
Thanks!!!

Thanks to all, it is not showing XX, it's showing 0psi. I will try reprogramming them, if not, then order new ones, now which one is the correct for a 2005? do they change per year?.
Thanks a lot for the help!!!!

Did you use your trusty hand held gauge to measure the rear tire pressures? XX means there is an issue with the sensor itself. A 0 PSI reading when you know there is pressure in the tire indicates the sensor is failing. You can play around with reprogramming the car to recognize the same sensor signal and get a few hours benefit or you can just bite the bullet and get new GM sensors. Don't go with Dorman as they have a tendency to fail within a month or two and you end up paying for another tire break down to get more new ones installed. Bob at House of Wheels has a reasonable price on GM sensors.
Oh, by the way your trusted hand gauge is no more accurate than the sensors. You can pay anything you want for a tire gauge but they are basically all equal. Liquid filled, 3 inch face, pencil, TPMS sensor, etc, etc, etc. They are equal until you calibrate one of them. They don't come calibrated and it isn't easy to find a place that will calibrate one and provide a calibration schedule that tells you how often you need to recalibrate.

FYI, unless you programmed the car in learn mode yourself to make sure that the TPMS are learned in the correct order/correct tire locations, never trust the actual location of the TPMS via the DIC. Also to point out, if the tires where pulled and put on the other sides with the TPMS reprogrammed, they will be stated in the wrong locations on the DIC as well.
As for a O reading, instead of XX, sounds like a programing problem and just relearning the TPMS to the car in learn mode should solve the problem (maybe, since the battery could be going dead, and on it last legs instead).
Also as stated, discount tire will relearn the TPMS to the car for free, and that alone may solve the problem.

Never trust the locations of the TPMS sensors unless you programmed them yourself...there have been many instances of incorrect locations here on the forum.

Good info in this thread. For the last couple months my right rear tire sometimes reads XX for a split second and then it's fine for a few more weeks. I imagine a new sensor is in my future.

Yep, sounds like you need one, they don't even take the tire off the rim just break the bead. Mines a 10'
