Exhaust Gas Temperature Sensor Circuit/Open Bank 2 Sensor 5

Where it lives

For P2485, the sensor sits on the circuit this code reports. The description of P2485 puts it on bank 2.

Check these first

• An open in the sensor 5 harness on bank 2
• A failed exhaust gas temperature sensor
• Corrosion at the sensor 5 connector
• A bad sensor 5 ground connection

What to do next

1. Read exhaust gas temperature sensor bank 2 sensor 5 on a scan tool
2. Test the sensor 5 harness for an open circuit
3. Check the sensor 5 connector for corrosion
4. Verify the sensor 5 ground is clean and tight
5. Replace the exhaust gas temperature sensor if the harness tests good
6. Clear the code and retest
