Code C2143 Toyota Description

The Tire Pressure Warning Valve and Transmitters that are installed in the tire and wheel assemblies measure the tire pressures. The measured values are transmitted to the Tire Pressure Warning ECU and Receiver in the vehicle as radio waves. The ECU compares the measured air pressure values with the air pressure threshold. When the measured air pressure value is less than this threshold, the warning light in the combination meter assembly illuminates.
When the internal circuit of a Tire Pressure Warning Valve and Transmitter is malfunctioning, this Diagnostic Trouble Code (DTC) is output.
