O2 Sensor Signals Swapped Bank 2 Sensor 2/Bank 2 Sensor 3

Where it lives

For P2417, the part to look at first is the sensor named here. The description of P2417 puts it on bank 2.

Check these first

• Bank 2 sensor 2 and sensor 3 connectors swapped
• Crossed wiring between the two bank 2 oxygen sensors
• A failed bank 2 sensor 2 or sensor 3
• A harness repair that misrouted the bank 2 sensor leads

What to do next

1. Compare bank 2 sensor 2 and sensor 3 signals on a scan tool
2. Verify each connector sits on the correct bank 2 location
3. Trace the bank 2 sensor wiring for crossed leads
4. Test each sensor for correct output
5. Reconnect or replace the affected sensor if the wiring is correct
6. Clear the code and retest
