C0091 4WD/AWD Power Transfer Unit Position Sensor A

4WD/AWD Power Transfer Unit Position Sensor A. The control module detected a fault associated with the 4WD/AWD Power Transfer Unit Position Sensor A circuit or function; the stored code identifies the affected component rather than a single failure mode.

C0091 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

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.
