Frequently asked questions about C056D
What does C056D mean?
Brake Pedal Position Sensor Supply Voltage Circuit Low. The control module detected that the signal in the Brake Pedal Position Sensor Supply Voltage circuit stayed below the expected operating range.
Is C056D generic or manufacturer-specific?
C056D is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C056D 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 C056D is removable in your case.
