- Faulty TPMS sensor in the tire
- TPMS module malfunction
- Wiring issues or corrosion in the TPMS system
- Interference from electronic devices or radio frequency signals
- Low battery in the TPMS sensor
Symptoms of C2121 2013 Toyota RAV4
- TPMS warning light illuminated on the dashboard
- Inaccurate or inconsistent tire pressure readings displayed on the instrument cluster
- Loss of communication with one or more TPMS sensors
- Increased risk of driving with underinflated tires
