Frequently asked questions about C003A
What does C003A mean?
Right Rear Wheel Speed Sensor. The control module detected a fault associated with the Right Rear Wheel Speed Sensor circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is C003A generic or manufacturer-specific?
C003A is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C003A 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 C003A is removable in your case.
