Frequently asked questions about C0645

What does C0645 mean?

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

Is C0645 generic or manufacturer-specific?

C0645 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove C0645 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 C0645 is removable in your case.
