Tire pressure monitoring system

No you cannot disable the Tire Pressure Monitoring System (TPMS) yourself (because it requires you to mess with the onboard computer system) but the dealer service center can. They probably will not do it though as the system is mandatory on cars sold in the US and they don't want to take any liability risks(nor will any other professional).

If the TPMS warning light is displaying and your tire pressures are at or above the recommended settings then normally one of the TPMS sensors(which are a combined sensor and tire valve fitting) fitted to one or more of the wheels has failed and needs to be replaced. The sensors will never last the life of the car and will need replacing more than once over the life span of the car.

Until the problem with the TPMS is fixed the warning light will remain. Frankly I would not worry about it unless the warning light is annoying you when driving. Just make sure you check your tire pressures regularly( to keep them at or above the recommended pressures ) which you should be doing anyway .

Using the Driver Information Center (DIC)
Important: After resetting, the tire pressure monitoring (TPM) system requires up to 8 km/h (5 miles) of flat, smooth road straight line driving in each of the 4 speed ranges to complete the calibration process. For further information, refer to Tire Pressure Monitor Description and Operation . If the TPM system does not reset, refer to Driver Information Center (DIC) Switch Inoperative .

1. Set all tire pressures to the recommended kPa/psi. Refer to Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label .
2. Turn ON the ignition, with the engine OFF.
3. Press the vehicle information button until TIRE INFLATION MONITOR SYSTEM PRESS (down/left arrow) SWITCH TO RESET is displayed.
4. If the system is being reset due to a low tire pressure condition, press and hold the down/left arrow button until TIRE INFLATION MONITOR SYSTEM HAS BEEN RESET is displayed. If the system is being reset due to a tire rotation, press and hold the down/left arrow button for 5 seconds.
5. Release the down/left arrow button and TIRE PRESSURE NORMAL is displayed.

It means you have a malfunction in the TPMS system. First you can try to do a reset as follows: 1. key on, engine off, parking brake on. 2. turn park lights on and off 4 times you will hear a horn chirp twice, you are in program mode. Start at L/F tire release air for 10 seconds, wait 15 seconds until horn chirp, after chirp go to R/F tire do the same until horn chirp then R/R let air out til the chirp then L/R do the same after the L/R chirp, turn key off and you are done, note you have only 5 min. to complete. If you do not hear horn chirp at each tire, you will have to start from beginning. When complete, remember to add air to each tire, 35 psi is recommended.
If that does not work you probably have a bad TPMS sensor, which will have to be replaced. Some auto parts stores will test your sensors for free, so check around.

You are right, the pressure sensors can be affected by temperature. If its below 10 Degrees there is a chance they will malfunction, I had a similar problem on my Jeep Wrangler and it required a heated garage for an immediate rectification. Alternatively, some tire shops have a computer which can communicate with the tire pressure sensors and reset the sensors once they determine that the correct air pressure has been applied to the tire.

If all tires are properly inflated you have 1 or more bad tire pressure monitors in your wheels. Will need to hook up to a tire pressure monitor scanner & it will tell you which one is bad. They are connected to the bottom of your valve stem in every wheel.

the TPMS light is the low tire warning light (Tire Pressure Monitoring System). Inside the drivers front door there will be a sticker that tells you what the tires should be inflated to. Check all the tires and make sure they are properly inflated. This should be done when the tires are cold.

TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. If your vehicle has this feature, sensors are mounted on each tire and wheel assembly, except the spare tire. The TPMS sensors monitor the air pressure in your vehicle's tires and transmit tire pressure readings to a receiver located in the vehicle.

The TPMS is designed to alert the driver, if a low tire pressure condition exists. This system also allows the driver to check tire pressure levels using the Driver Information Center (DIC).

When a low tire pressure condition is detected, the TPMS displays the "CHECK TIRE PRESSURE" warning message on the DIC, and at the same time illuminates the low tire pressure warning symbol.

You may notice, during cooler weather conditions, that the tire pressure monitor light, located on the instrument panel cluster, and the "CHECK TIRE PRESSURE" message will appear when the vehicle is first started and then turn off as you start to drive the vehicle. This could be an early indicator that the tire pressures are getting low and need to be inflated to the proper pressure.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

The "CHECK TIRE PRESSURE" warning message and low tire pressure light (telltale) will appear at each ignition cycle until the tires are inflated to the correct inflation pressure.

The Tire and Loading Information label (tire information placard) shows the size of your vehicle's original tires and the correct inflation pressure for your vehicle's tires when they are cold.

Your vehicle's TPMS can alert you about a low tire pressure condition but it does not replace normal tire maintenance.

NOTICE: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors.

RESETTING THE TPMS IDENTIFICATION CODES
Each TPMS sensor has a unique identification code. Any time you rotate your vehicle's tires or replace one or more of the TPMS 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: LF TIRE (left front tire on the driver's side of the vehicle), RF TIRE (right front tire on the passengers side of the vehicle), RR TIRE (right rear tire on the passengers side of the vehicle), and LR TIRE (left rear tire on the driver's side of the vehicle).

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 process is outlined below:

1. Set the parking brake.
2. Turn the ignition switch to "RUN" with the engine off.
3. Turn the headlamp switch from "OFF" to the parking lamps setting 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 indicate that the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The "SERVICE TIRE MONITOR" message will be displayed on the Driver Information Center (DIC).
4. Start with the driver's side front tire.
5. 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 1. 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.
6. Proceed to the passenger's side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger's side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver's side rear tire, and repeat the procedure in Step 5.
9. 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 to exit the sensor matching process. 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.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.
11. Put the valve caps back on the valve stems. The spare tire does not have a TPMS sensor. If you replace one of the road tires with the spare, the "CHECK TIRE PRESSURE" message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPMS sensor. The "SERVICE TIRE MONITOR" message is displayed when the TPMS is malfunctioning. One or more missing or inoperable TPMS sensors will cause the service tire monitor message to be displayed.

The TPM System is the Tire Pressure Monitor. Each wheel will have a tire pressure sensor that monitors the tire pressure of each wheel and send that information to a computer. If the computer is not receiving the proper information it will let you know. If the low tire light is on and not flashing than it may be something as simple as a low tire. The proper tire inflation will be inside the drivers front door on the build sticker.

If all the tire pressures are o.k. than you will need to get the TPMS scanned to see why it is not working. Chryslers are pretty common for pressure sensors to fail.

Your tire pressure is monitored by a device known as a TPMS sensor.

Tire Pressure Monitoring System is an integral part of your tire that tends to wear with age.

You need to take your vehicle to a reliable shop (I recommend Discount Tire) to have the TPMS sensor in the defective tire replaced. It's simple, and inexpensive.

I have used Discount Tire's services for almost 20 years, and have never been disappointed with their service.

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....
