From 2005 STS Owners manual:
Each TPM sensor has a unique identification code. Any
time you replace one or more of the TPM sensors,
the identification codes will need to be matched to the
new tire/wheel position. Each tire/wheel position is
matched, to a sensor, by increasing or decreasing the
tire’s air pressure. The sensors are matched, to the
tire/wheel positions, in the following order: left front (LF),
right front (RF), right rear (RR), and left rear (LR).
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/wheel positions the
matching process stops and you will need to start over.
The TPM matching process is outlined below:
1. Set the parking brake.
2. Press the push-button ignition switch to OFF/ACC.
3. Using the Keyless Access transmitter, lock and
unlock the vehicle’s doors.
4. Press the lock and unlock buttons, at the same
time, on the Keyless Access transmitter. A single
horn chirp will sound, indicating that the TPM
system is ready, and the sensor matching process
can begin.
5. Start with the left (driver’s side) front tire.
6. Remove the valve cap from the valve stem.
Activate the TPM sensor by increasing or
decreasing the tire’s air pressure for five seconds,
or until a horn chirp sounds. The horn chirp,
which may take up to 30 seconds, confirms that the
sensor identification code has been matched to
this tire position. To decrease the tire’s air-pressure
use the pointy end of the valve cap, a pencil-style
air pressure gage or a key.
7. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 6.
8. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 6.
9. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 6.
10. After hearing the confirming double horn chirp, for
the left rear tire, exit the matching process by
turning the ignition switch to OFF/ACC.
11. Set all four tires to the recommended air
pressure level as indicated on the tire and loading
information label.
12. Put the valve caps back on the valve stems.

This worked like a champ for me. I purchased a 2 pack of ceramic ring magnets MODEL 542021 from Lowe's and followed the magnet fix. I actually placed both magnet over top of the valve stem and mind them back and forth slow and it worked like a charm!

Tire pressure light is staying on in instrument panel. checked tire pressures. all correct

There are two typical types of tire pressure monitoring systems, direct and indirect. Direct TPMS uses individual battery powered sensors on each wheel to report tire pressure to the computer and if this is the case one of your sensors may have failed. Indirect TPMS uses a combination of values measured externally to each wheel (rotation velocity, temperature, etc.) then the computer calculates nominal values and indicates when a wheel is performing outside those nominal values thus indicating a potential low tire pressure situation. Any false indications with an indirect TPMS may be due to a fault within the ECU (computer) or other feedback sensor.

How do you reset tire pressure monitors on 2006 Cadillac STS

TPMS readers are expensive, they are specialty and are not easily available. You can go to a dealer, you can try a tire shop, but it is something that you cannot do yourself. Dealers are the most expensive to have this done at.

My Cadillac devil 2004 is prompting me saying"tire monitoring sensor" isn't wiring or need to be replaced. I'm a do it yourself kind of guy is this something I can fix myself ? And what's my best plan

The TPMS monitors tire pressure and sends a signal to the Cadillac's computer when there is low tire pressure. When the tire pressure is restored, the Cadillac's TPMS should reset itself. However, if it does not, the TPMS light on the dash will stay lit. When this happens, you need to know how to manually reset the TPMS light and sensors.


1 Press and hold the tip odometer button on the gauge cluster.

2 Wait until the display screen brings up the settings menu.

3 Release the "reset" button and press it again to scroll through various settings.

4 Keep pressing the "reset" button until you come to the TPMS setting.

5 Press and hold the "reset" button until the TPMS light on the dash resets.

2010 cobalt need 2 know how 2 reset low tire pressure monitor

The low tire pressure warning should go out if you set all of the tire pressures to the correct pressure, then drive the vehicle for about a mile. You should not have to "relearn" the Tire Pressure Monitoring System (TPMS) unless the tires are (A.) rotated into different positions or (B.) There is a bad sensor that needs to be replaced.

For more information, you can read the information in your Owner's Manual. Here is a link to a pdf version 2009 Cobalt owners manual. (The information and procedures are the same for 2008 - 2010 Cobalts) The TPMS section starts on page 5-64

You either have low tire pressure in a tire
A bad tire pressure sensor in a wheel
Or just need to reset the TPMS,if you rotated your tires.

Go to a shop with a TPMS tool or scanner with TPMS software, and have it reset.

This is my first cadillac, I just bought it... This is my first cadillac I just bought it yesterday and today it keeps saying " Service Tire Monitor" what does that ...

Service Tire Monitor means that one or more of your tires are underinflated, causing an out of balance condition that it can detect through the wheel speed sensors.

The code should be covered in your manual, to tell you how to reset it after the tires are inflated evenly to manufacturer's specifications.

I would check the sizes of all your tires to verify that they are the same type and size recommended by Cadillac. Also, check the tire inflation in all 4 tires to make sure they are even.

Then, follow the instructions in your manual on how to turn the 'Service Tire Monitor' light off.

If you don't have a manual, you might go to the website and look under 'owners' and you can sign on to Yahoo! and get a free manual downloaded to your computer for viewing or printing, I believe.

It will come back on if the tires are unevenly inflated as you go down the road several miles.

Ford Windstars, also, have this feature. A lot of newer cars past the year 2000 have this feature which helps you to monitor the pressures and avoid getting a flat tire on a long trip.

Good luck travelling in your first Cadillac.

I have 3 Cadillacs at my disposal, a 1976 Seville, a 1990 Deville, and a 1997 Deville Limo and I love all of them, although the 1976 and 1990 need paint jobs here in Pennsylvania's harsh weather.

2005 sts code states service suspension and service wheel sensors

So does my 2006 STS....!
On the Tire monitoring subject.... The next time it tells you to service it, scroll through and see if the system is reporting a tire pressure for each tire, if it is, and there is not all dashes for one of the tires, there is nothing to worry about.
Note.... aftermarket rims, tire sealants and tire rotations done without "relearning wheel sensor positions", (page 5-67 in your manual), can cause a "DTC" (Diagnostic Trouble Code) to display and tell you to service it.
On the stability system, I have to do some more digging....
