OBD-II DTC Trouble Code Description
O2 Sensor Signals Swapped Bank 1 Sensor 2 / Bank 2 Sensor 2
What does that mean?
This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the make and model. Owners of these these brands may include but are not limited to BMW, Dodge, Ford, Chrylser, Audi, VW, Mazda, Jeep, etc.
In a nutshell, a P0041 code means that the vehicle’s computer (the PCM or powertrain control module) has detected that the O2 oxygen sensors downstream from the catalytic converter have swapped wiring.
