Frequently asked questions about C009E
What does C009E mean?
4WD/AWD Rear Differential Unit Actuator B Position Sensor B. The control module detected a fault associated with the 4WD/AWD Rear Differential Unit Actuator B Position Sensor B circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is C009E generic or manufacturer-specific?
C009E is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C009E 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 C009E is removable in your case.
