Frequently asked questions about C0587

What does C0587 mean?

Brake Booster Motor A Position Sensor Circuit/Open. The control module detected an interruption (open circuit) in the Brake Booster Motor A Position circuit, so the expected electrical continuity was not present.

Is C0587 generic or manufacturer-specific?

C0587 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove C0587 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 C0587 is removable in your case.
