Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 5

Where it lives

For P2486, the circuit described runs through the sensor. The description of P2486 puts it on bank 2.

Check these first

• A sensor 5 element shorted to ground on bank 2
• A signal wire shorted to ground
• A poor sensor 5 connector connection
• An intake or exhaust leak skewing the reading

What to do next

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