Code C2123 2014 Toyota RAV4 Description
The C2123 diagnostic trouble code (DTC) for a 2014 Toyota RAV4 indicates that there is no signal being received from Transmitter ID 3 in the main mode. In simpler terms, this means that the vehicle's tire pressure monitoring system (TPMS) is not able to communicate with one of the tire pressure sensors, specifically the sensor assigned to ID 3. This can lead to inaccurate tire pressure readings being displayed on the dashboard, potentially compromising the safety and performance of the vehicle.
Common Causes of C2123 2014 Toyota RAV4
- Faulty Transmitter ID 3 tire pressure sensor.
- Malfunctioning TPMS module.
- Wiring issues or poor connections in the TPMS system.
- Interference from external electronic devices affecting TPMS signals.
- Low battery voltage in the tire pressure sensor.
Symptoms of C2123 2014 Toyota RAV4
- TPMS warning light illuminated on the dashboard.
- Inaccurate tire pressure readings displayed on the instrument cluster.
- Fluctuating tire pressure readings while driving.
- Loss of communication with one or more tire pressure sensors.
- Potential impact on vehicle stability and handling due to incorrect tire pressure.
