Common fault codes for 4-sensor TPMS.

A 4-sensor Tire Pressure Monitoring System (TPMS) uses individual pressure sensors in each wheel to provide precise, real-time data. When the system detects an issue, it stores Diagnostic Trouble Codes (DTCs) that can be read with an OBD-II scanner. Understanding these codes is crucial for accurate diagnosis and repair. The most common codes relate to sensor communication failures, low battery warnings, and system malfunctions.
