TPS sensor...
one of my TPS is stuck at 27ps, the tire is actualy at 30 psi but my car shows 27 for that tire, the rest of the tires are fine and reading correctly. There is something I sould try to do before changing it?
If I have to change it, do you have an idea how much it is? any tire shop can program it? what brand name should I buy?
Thanks

Is the sensor really "stuck" at 27 psi...or is it just 3 psi off? If you put 40 psi in that tire, what will that sensor read? 
TPMS sensors aren't necessarily the most accurate devices for measuring actual tire pressure. Use a quality tire pressure gauge to do that.

Well in my case, I got in the car a little earlier today and as soon as I started it up I received a low tire pressure on the right rear. The DIC was reading 23 psi. I checked it with my gauge and it shower 30 psi. I then checked it with a second gauge and it also read 30 psi. After driving it a few miles the warning went away, but it only showed 24 psi and only reached 26 psi when I pulled back in the garage. A recheck with the gauge showed 35 psi. So in my case I believe I need a new TPMS in that wheel.

you didnt say exactly if you checked all the tires using your gauge. you just said the other tires read right (from dic?) if you didnt actually use tire gauge on all tires, then its possible that the sensor is actually registering from another tire, which is actually low.

I have only had this car 2 weeks, so I am wondering if maybe the last owner switched the tires from side to side and that is why it indicated the wrong side.

Thanks for that info. I just went out in the garage and sure enough, it was the left rear that was low, even though the DIC said Low Pressure Right Rear. I never knew they could read another tire. I never had that happen in my C5. Went it indicated a specific side front or rear it was correct.

yes Increase and lower the psi in that tire and is still stuck in 27 and I have been using a gauge to do the readings.

please read every tire with your tire pressure gauge. report here what each tire reads. report which tire the DIC thinks is low.
also like MLBC said above, did you drive for a little while for it to attempt reset?
thanks
p.s. i reread my above and i sorta sound grumpy. didnt mean to, just want the facts. lol

sorry but again, until you actually say you checked every tire with a tire pressure gauge, i aint sure you did and cant assume you did. reading correct might mean DIC says they are fine...

If that does nothing, I would think the electronics are the culprit.

You may just simply need to have a relearn procedure performed to reprogram the tire pressure sensors into the TPMS computer in the car again.
If you do need a sensor, the 2005-2009 use GM part# 25758220, and the 2010 and newer use GM part# 15268606, but that sensor may not be available through many sources anymore because its been superseded by part# 20925924.
A new GM sensor can cost from about $50 from a forum vendor, to well more than $75 if you go to your local Cheby dealer's parts department.
I like the OE sensors, which are made by Schrader, but Oro-Tek and Orange electronics make ones that are reported to work well. Reports here on the forum haven't been real good for the Dorman ones, so I'd avoid them.
Any tire shop can install the new sensor, and that will require a relearn procedure to reprogram all of them into the TPMS computer.

Sounds like the transducer....one thing to try is to lower the tire pressure to 0, technically the DIC should read 15....if there is some kind of blockage in the sensor, the differential pressure between the sensor side and the 'flat' tire may dislodge it....
If that does nothing, I would think the electronics are the culprit.
