To reset the tire pressure monitoring system on a 2019 Porsche Cayenne, follow these steps that can be completed in 3 to 5 minutes. Begin by sitting in the driver's seat with the ignition turned on, but do not start the engine. Find the tpms button located to the right of the steering wheel and press and hold it until the light flashes three times. Release the button and start the engine. Allow the engine to run for 8 to 10 minutes to complete the TPMS reset process.

To recalibrate the tire pressure monitoring system (TPMS) on the 2019 Porsche Cayenne, first ensure that the tire pressure is accurate. Start the vehicle and press the reset button located to the right of the steering wheel. Wait for ten minutes. In certain situations, you might have to hold down the button until the light blinks. If the sensor malfunctions, it could be due to incorrect tire pressure, resulting in poor performance of the vehicle.
Randy D.'s advice is for older Cayennes and may not be relevant to newer models like my 2012 one, or likely even 2011 models. However, it's useful for the earlier versions. For the newer models, you can access the TPMS reset by using the correct toggle on the steering wheel and the instrument panel. In my case, this method didn't work. However, Porsche has sent letters about defective wheel speed sensors that can be replaced for free, which I think is what I need to do. Keep cruising, fellow Porsche enthusiasts!
