Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 1

Where it lives

For P0549, the circuit described runs through the sensor. The description of P0549 puts it on bank 2.

Check these first

• An open EGT sensor on bank 2 sensor 1
• A signal wire open or shorted to voltage
• An exhaust restriction on bank 2
• An exhaust leak on bank 2
• A sensor installed the wrong way

What to do next

1. Read bank 2 EGT data on a scan tool
2. Test the circuit for an open or short to voltage
3. Check for an exhaust restriction on bank 2
4. Verify the sensor orientation
5. Replace the EGT sensor if the high reading persists
6. Clear the code and retest
