Code C2122 2014 Toyota RAV4 Description
The diagnostic trouble code C2122 for a 2014 Toyota RAV4 indicates that there is no signal being received from Transmitter ID 2 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. The TPMS is a crucial system that monitors the air pressure in each tire and alerts the driver if there is a significant deviation from the recommended pressure. When the system is unable to receive a signal from one of the sensors, it can lead to inaccurate tire pressure readings, potentially compromising the vehicle's safety and performance.
Common Causes of C2122 2014 Toyota RAV4
- Malfunctioning tire pressure sensor
- Faulty wiring or connections in the TPMS system
- TPMS control module failure
- Low battery in the tire pressure sensor
