So the light came on for the TPM (tire pressure monitor) that yellow triangle. The right rear quit working. So a little research, just about most GM vehicles from 2005 to 2010 that use Schrader brand TPM sensors 95% of them are interchangeable. You can install them yourself with minimal tools and even program them with your key fob. First take your tire off and remove the valve stem core. Be sure to put your hand on it when removing or it will launch to never be seen again. After all the air is out take a fairly long 2x4 and put it under the frame of the car. Place a small block of wood where the tire is by the TPM. What you are gonna do is break the outer seal of the tire. So you can push down and take it out and put in the other one. They unscrew from the outside with a wrench, then slide into the rim.your gonna use leverage to break the top seal (one facing towards everyone and not the inner fender). Once you swap them out, fill your tire. Better have a decent compressor or forget it. It will pop and is kinda loud but youll be ok. A little soap water on the bead helps too. Just don't get in the tire or you'll get some real weird vibrations next time you drive it. After the tire is on your car now programming the TPM sensors. You can also do this after rotating tires. Start by sitting in the car with key in the on position, but not started. Press and hold the LOCK and UNLOCK buttons simultaneously for a few seconds, then release, you will hear the horn honk twice and the front driver turn signal light will come on, on the fender. Indicating this is the first tire to set. This system takes a sample of the air pressure every 30 seconds. If it notices a change of more than 1.2 lbs while in program mode it will chirp once indicating that tire has been successfully "paired" in that #1 position. then the passenger turn signal will come on and the driver goes off. repeat this procedure in this order, front driver, front passenger, rear passenger, rear driver. Once the rear driver is done that one will double honk. Thus exiting program mode. If any one of your tires fail to honk during this procedure, you still have a bad sensor and it will have to be replaced. If you do this and have a bad sensor, you can shut the key off and it will exit this mode. WARNING if you do not pair all four tires NONE will work now till you PAIR ALL FOUR. You will just see "dashes" (-----) on the readout where the pressure reading used to be on the info center for each tire.:surprise: :grin2:

It's not too bad. As long as you only pop the top seal you shouldn't have to get your tire rebalanced. You can always take it to a tire shop and have them either dismount it or replace it for you. Just do not let them charge you the ridiculous amount to "flash" it to the computer. That's the whole purpose of this post. Info on pairing, reprogramming, flashing, whatever term you may use to get the TPM's to connect to your car and in the right location for a repair or tire rotation. Yes you have to do this when you rotate tires or it might tell you the front left is low and it's really the rear.
