Code C2122 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.
The Tire Pressure Warning Valve and Transmitters constantly send radio waves to the Tire Pressure Warning ECU and Receiver.
Under the conditions below, the Tire Pressure Warning ECU and Receiver is unable to receive the signals from the Tire Pressure Warning Valve and Transmitters, and a Diagnostic Trouble Code (DTC) is stored.
- Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.
- Devices using similar radio frequencies are used in the vehicle.
- The ID of the tire pressure warning valve and transmitter is mistyped during registration.
- A tire, wheel, and/or transmitter from a different vehicle is installed.
