Code C1723 Description

A sensor-transmitter integrated with a valve is installed in each wheel. It transmits a detected air pressure signal in the form of a radio wave when the vehicle is moving. The radio signal is received by the tire pressure receiver and send to the Body Control Module (BCM). The BCM monitors the sensor-transmitter. The BCM sets the OBDII code when the sensor-transmitter signal is not to factory specifications.
