Tire pressure sensors

[TA8088]

Anybody know a part number or rough idea of the cost of the tire pressure sensors? When I get my new rims and tires I'd like to put new ones in so that I don't have to strip them from my factory wheels.

Thought it worked off the speed sensors?

From what I've been told it's part of the valve stem assembly.

They are part of the valve stem assembly. Normally, I would be able to get a part number, but the parts system viewer is down right now.

System is back up:
15122618 SENSOR,TIRE PRESS IND. About $49.00 each. Includes the valve stem, grommet and nut.

Thanks fstop!! Using the part # you supplied I was able to find them at GMPartsDirect for about $28 each. I was told that I would need to have the sensors programed for me so that they work. I was also told that the spare has one and that I could pull that one so that I only have to buy three.

I'll save you some money, and offer a bit of advice.
First, I would purchase all four, since if you have to use the spare, and it has no sensor, you will get a TPM message, that is up to you though.
However, no need for a dealer to program, you can do the learn procedure supplied in the owner's manual. That is all the dealer will do. It takes a dealer a less time since they can use the TPM tool, but why pay them a minimum of one-hour work, if you can do the same thing in about fifteen or twenty minutes.
The TPM tool just activates the sensors to produce a low frequency transmission that the BCM learns.
In the owner's manual procedure, it tells you to inflate or deflate a tire, this is causing the sensor to sense a change in air pressure, thus signalling the BCM, and then the BCM learns the sensor.
So, doing it yourself might save $50-70.00.

TPM Sensor Learning
Each TPMS sensor has a unique identification code. Any time you rotate your vehicle's tires, install the spare tire onto your vehicle, or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. The sensors are matched to the tire/wheel positions in the following order: driver's side front tire, passenger's side front tire, passenger's side rear tire, and driver's side rear tire.

You will have one minute to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than one minute, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you will need to start over.

The TPMS sensor matching procedure is outlined below:

Set the parking brake.
Turn the ignition switch to ON with the engine off.
Turn the exterior lamp switch from AUTO to ON four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light will begin to flash. The double horn chirp and flashing TPMS warning light indicates the TPM matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The SERV TPM message will be displayed on the Driver Information Center (DIC).
Start with the driver's side front tire.
Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position. If you do not hear the confirming single horn chirp, you will need to start over with step number one. To let air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage, or a key.
Proceed to the passenger's side front tire, and repeat the procedure in Step 5.
Proceed to the passenger's side rear tire, and repeat the procedure in Step 5.
Proceed to the driver's side rear tire, and repeat the procedure in Step 5.
After hearing the confirming horn chirp for the left rear tire, check to see if the TPMS warning light is still flashing. If it is, turn the ignition switch to LOCK. If the TPMS warning light is not flashing, the five minute time limit has passed and you will need to start the process over beginning with Step 1.
Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.
Put the valve caps back on the valve stems.

Wow!! Thanks again fstop. Not only was I able to find a great price on them with the part number you gave me now you've saved me another $50-100 with the instructions you gave me. This forum is a great place because of members like you.

f5fstop if I change my tires not the rims from the 265/75r/16 to the 285/75r/16 would I have to reprogram my tire sensors ?

As long as you keep the same sensor in the same location the answer is no. The BCM learns the location of the sensor. The relearn procedure is when you have to rotate the tires.
I have played with it, and it does work.
I have also heard, that if you rotate the tires and do a few drive cycles, the BCM will relearn without the inflating and/or deflating of the tires.
When I rotate my tires, I will do a few drive cycles to see if this will work. If it does, great, if not, I'll grab the TPM tool at work and program the sensors, and then clear the codes.

$28.00 each wow, they cost $123.00 up here in Canada

I had new tires installed, and who knows what wheel got put back where. I took it out the next day and when I engaged the 4 low, I got the SERV TPM message. After I came out of Low, I got the message again for a little while, The light has not since come on. This leads me to believe that your theory of the system re-learning is correct. Thanks so much for your post though, I now know what to do when I rotate the tires. They are right, this forum is great!
