Tire pressure sensor fault

That signal is from your tire monitoring sensors, telling you that there is air pressure difference between tires. The tire pressure should be same in all tires.

{: ) The 2002 Oldsmobile uses the TIM system. Here is an overview of how it works:
The tire inflation monitoring (TIM) system detects the differences in tire rotation speeds that are caused by changes in tire pressure. The TIM may not alert the driver if the pressure in more than one tire is high or low. The TIM also may not operate properly if the spare tire is in use.
The TIM system can alert the driver when a large change in the pressure of one tire exists. The system only detects a low pressure condition while the vehicle is being driven.
The LOW TIRE PRESSURE indicator turns ON in the instrument cluster if the tire pressure in one tire becomes 12 psi (55 kPa) lower or higher than the other 3 tires and the ignition switch is in the ON position. The message does not appear if more than one tire is low or high, or if the system is not calibrated properly. The system does not inform the driver which tire is low. In order to clear this message, equalize the tire pressures in all 4 tires and perform the Tire Inflation Monitor Resetting. In addition, the indicator may come ON if a low voltage condition is present.

In other words, this is not like the TPM (Tire Pressure Monitoring) system that is being used in later model vehicles, wherein the TPM sensors are inside the wheel, integrated to the tire valve. The TPM sensors detect changes in tire pressure and temperature, and sends out radio signals to the RCDLR, to be decoded by the BCM and the instrument cluster.

Sounds like you will need the transmitting unit replaced - it is located behind the stem inside the tire...

Touaregs have a learn mode that you access through the instrument cluster. You use the buttons on the steering wheel to navigate to it. Once you turn on the learn mode, you have to drive it quite a while for the light to go off, approx 20 minutes. The light will either go off, or the cluster will give you a fault message.

You have to use a scan tool. just check all tire pressures and set then to the proper pressure. the right pressure is on the door sticker. if the light does not go out after that. then you will have to use a scan tool to tell what tire sensor is not correct. F.Y.I. If you used fix a flat or a simular product in a tire, it will destroy a tire sensor.

tahoe 2007 tire press problem

It is on the same button as the Trip Odometer. Cycle through until you see Tire Reset and hold the button down.

The system has to be reset from the MMI under tire pressure monitoring using th changewheel option

local tire dealers can get the sensor from car dealer, install & calibrate

Wow another great problem by a dodge product i would check for a recall on the sensor switch
