Frequently asked questions about C057C

What does C057C mean?

Brake Booster Temperature Sensor B CircuitRange/Performance. The control module judged the Brake Booster Temperature Sensor B behaviour implausible for the current operating conditions.

Is C057C generic or manufacturer-specific?

C057C is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove C057C 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 C057C is removable in your case.
