P0041
Downstream Oxygen Sensors Swapped From Bank To Bank
DTC P0041, sometimes indicated as P004100 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing downstream oxygen sensors swapped from bank to bank.
The P0041 code means that the downstream oxygen sensors are swapped from bank to bank. This could be caused by a wiring problem, a bad oxygen sensor, or a problem with the engine control module.
Possible solutions include checking the wiring, checking the oxygen sensors, and checking the engine control module.
