The definitive way to determine if a Tire Pressure Monitoring System (TPMS) sensor requires full replacement, rather than just suffering from a depleted battery, is to perform a diagnostic procedure that checks for physical damage, internal electronic failure, and specific fault codes.

The core distinction lies in identifying symptoms that go beyond simple power loss.
The B0083 fault code is a manufacturer-specific OBD-II diagnostic trouble code. In General Motors (GM) vehicles, it is most commonly defined as the “Right Front/Passenger Seat Position Sensor (SPS) Circuit”.
