Code C1723 Description

The C1723 diagnostic trouble code (DTC) indicates that there is a malfunction in the function code data from the rear left transmitter. In modern vehicles equipped with tire pressure monitoring systems (TPMS), each wheel is equipped with a sensor that transmits data to the vehicle's computer system. This data includes tire pressure, temperature, and other relevant information. The transmitter on the rear left wheel is not sending accurate or consistent data to the system, which can lead to inaccurate readings and potentially compromise the safety and performance of the vehicle.
