P0041 Cadillac Code - Oxygen Sensor Signal Swapped Bank 1 Sensor 2 / Bank 2 Sensor 2
Quick Answer
The heated oxygen sensor (HO2S) monitor determines if the HO2S signal response for a fuel shift corresponds to the correct engine bank. Common causes include Crossed HO2S harness connectors, Crossed HO2S wiring at the harness connectors, Crossed HO2S wiring at the PCM connectors. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
