Frequently asked questions about C003B
What does C003B mean?
Right Rear Wheel Speed Sensor Supply. The control module detected a fault associated with the Right Rear Wheel Speed Sensor Supply circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is C003B generic or manufacturer-specific?
C003B is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C003B 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 C003B is removable in your case.
