2002 olds aroura comp. readout says low tire presser.

Hi Patricia I google your question and the link below says 215/60-16
CHEERS..

Often times driving the car will reset the TPMS system. If it persists, it may need one or more tire pressure monitors replaced and reprogrammed.

Look in your owners manual

most likely culprit is the tps itself they go bad if air is good all around then usually the sensor goes most go when fix a flat is used it shorts them out when you go to change tire replace the bad one cost anywhere from $ 5 to $ 25 online

{: ) 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.

16 INCH OR BIGGER TIRES TIRE PRESSURE IS AT LEAST 44 PSI. YOUR TIRES PRESSURE STILL LOW.

Does not reset it self must be reset on radio

The "Check Tire Pressure" message can come on due to tire wear, even though your tire pressure is fine. Bring up the message and then hold the reset button until the tire pressure restes to normal.

You have to "Teach" the tire sensors to the correct pressure. The 02 Sienna does not measure the actual PSI tire pressures, it measures the RPM of the tires. with the tires set to specs, the rotation RPM is "x". If a tire goes low, the rotation RPM would bt "y", and that will light the light.

The proceedure: Set the tires to specs with a known good pressure gauge. The ones that you can put in your pocket, that looks like a pen, are alway sincorrect. Get one with a needle reading. Set the tires correctly. Now, press the reset button, hold it until the light blinks 3 times. Drop it into gear, and DRIVE IT. 8-12 miles, above 19 MPH, and UNDER 61 MPH. This will re-teach the ABS computer the correct values.

All tire pressures have to be close to the same to turn of low tire waning. Th change oil is reset easily, and the directions should be in your owners manual.
