Oxygen sensor signals swapped, bank 1 sensor 2/bank 2 sensor 2
Generic · emissions
Data confidence90%
The control module detected a fault associated with the Oxygen sensor signals swapped, bank 1 sensor 2/bank 2 sensor 2 circuit or function; the stored code identifies the affected component rather than a single failure mode.

Oxygen sensor signals swapped, bank 1 sensor 2/bank 2 sensor 2. The control module detected a fault associated with the Oxygen sensor signals swapped, bank 1 sensor 2/bank 2 sensor 2 circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is P0041 generic or manufacturer-specific?
P0041 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove P0041 at file level?
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
