Abstract
An apparatus and method is provided that includes measuring a tire pressure for at least one tire with at least one tire pressure sensor. The tire pressure sensor has at least a first resolution for transmitting pressure information and a second resolution for transmitting pressure information that is higher than the first resolution. If a measured tire pressure is determined to be above a predetermined pressure threshold, the apparatus and method identify whether the tire pressure sensor has experienced at least one predetermined vehicle operating characteristic, and/or identify whether the tire pressure sensor has been activated by a command. The tire pressure sensor is only locked into the second resolution if the tire pressure sensor has experienced the at least one predetermined vehicle operating characteristic or if the tire pressure sensor has been activated by the command.
