Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 4

Where it lives

For P2475, the circuit described runs through the sensor. The description of P2475 puts it on bank 2.

Check these first

• A sensor 4 element shorted to ground on bank 2
• A signal wire shorted to ground
• A water soaked sensor 4 connector
• A failed exhaust gas temperature sensor

What to do next

1. Read exhaust gas temperature sensor bank 2 sensor 4 on a scan tool
2. Test the sensor 4 signal wire for a short to ground
3. Inspect the sensor 4 connector for water intrusion
4. Check the sensor 4 reference voltage
5. Replace the exhaust gas temperature sensor if the circuit tests good
6. Clear the code and retest
