P0041 - O2 Sensor Signals Swapped (Bank 1 Sensor 2/Bank 2 Sensor 2)
System InformationO2 sensors are used to monitor the Oxygen content in the exhaust system, there will normally be a sensor before the catalyst (sensor 1) and one after the catalyst (sensor 2)
Fault Code Explained
the PCM has detected that the signals for the two sensors are the wrong way round. This fault is most likely due to the multi plugs being connected incorrectly.
Check and swap multiplugs for the two affected sensors
