Code C2143 Toyota Description

The C2143 Toyota diagnostic trouble code (DTC) specifically refers to a "Transmitter ID 3 Error." This code is typically associated with issues related to the tire pressure monitoring system (TPMS) on the vehicle. The TPMS is designed to monitor the air pressure in each tire and alert the driver if there is a significant deviation from the recommended pressure. When the vehicle's onboard computer detects a problem with the Transmitter ID 3, it triggers the C2143 code.
