Code C2143 Lexus Description

The C2143 code for Lexus vehicles indicates a Transmitter ID 3 Error, which typically refers to an issue with the tire pressure monitoring system (TPMS). The TPMS is responsible for monitoring the air pressure in the tires and alerting the driver if there is a significant drop in pressure. When the Transmitter ID 3 Error code is triggered, it means that there is a communication problem with the TPMS sensor located in the third wheel position. This can lead to inaccurate tire pressure readings, potentially putting the vehicle at risk of tire blowouts, decreased fuel efficiency, and overall compromised driving safety.
