Frequently asked questions about C0579

What does C0579 mean?

Brake Booster Temperature Sensor B Circuit Low. The control module detected that the signal in the Brake Booster Temperature Sensor B circuit stayed below the expected operating range.

Is C0579 generic or manufacturer-specific?

C0579 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove C0579 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 C0579 is removable in your case.
