1. A tire pressure sensor for a motor vehicle having a tire pressure monitor, the tire pressure sensor comprising:
- a non-Bluetooth wireless receiver located inside a vehicle tire, the non-Bluetooth wireless receiver being configured to;
receive from the vehicle tire pressure monitor, a first, non-Bluetooth low-frequency (LF) wireless message when the non-Bluetooth wireless receiver is inside the vehicle tire, the received first non-Bluetooth message being formed using one of a plurality of different types of first wireless message protocols;
while the non-Bluetooth wireless receiver is inside the tire, identify a particular type of wireless message protocol that was used to form the received first non-Bluetooth wireless message; and
generate a non-Bluetooth output message to a non-Bluetooth wireless transmitter co-located with the non-Bluetooth wireless receiver while the non-Bluetooth wireless receiver is inside the vehicle tire, the non-Bluetooth output message from the non-Bluetooth wireless receiver comprising an identifier, which identifies the non-Bluetooth wireless message protocol by which the received non-Bluetooth first wireless message was formed by the vehicle tire pressure monitor; and
a non-Bluetooth wireless transmitter co-located with the non-Bluetooth wireless receiver inside the vehicle tire, the non-Bluetooth wireless transmitter being coupled to the non-Bluetooth wireless receiver, and configured to transmit to the tire pressure monitor from inside the tire, a second, non-Bluetooth, high-frequency message containing tire information using a second non-Bluetooth wireless message protocol, which is selected in response the identifier for the tire pressure sensor;
wherein the reception of the first non-Bluetooth message by the non-Bluetooth wireless receiver, the identification of the first non-Bluetooth wireless message protocol by the non-Bluetooth wireless receiver and selection of the second non-Bluetooth wireless message protocol by the non-Bluetooth wireless receiver takes place inside the tire.

Abstract
In a vehicle tire pressure sensor, a wireless, low frequency (LF) receiver identifies a particular type of signal protocol that was used to form a first message that is sent to the sensor by the vehicle. Using the identification of the protocol used to form the first message, the sensor determines a type of signal protocol to be used to transmit information to the vehicle, such as an identifier for the tire pressure sensor in a second message.
