|P0041 – Oxygen Sensor Signals Swapped Bank 1 Sensor 2/Bank 2 Sensor 2|
|Description: The heated oxygen sensor (HO2S) monitor determines if the HO2S signal response for a fuel shift corresponds to the correct engine bank. The test fails when there is no response from the HO2S being tested.
Possible Causes: • Crossed HO2S harness connectors
• Crossed HO2S wiring at the harness connectors
• Crossed HO2S wiring at the PCM connectors
Diagnostic Aids: Connect the HO2S connector to the correct bank.
