Frequently asked questions about C0634
What does C0634 mean?
Brake Pressure Sensor A/B Correlation. The control module detected a fault associated with the Brake Pressure Sensor A/B Correlation circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is C0634 generic or manufacturer-specific?
C0634 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C0634 at file level?
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether C0634 is removable in your case.
