Exhaust Gas Temperature Out of Range Bank 1 Sensor 3

Where it lives

For P247A, start at the sensor the description names. The description of P247A puts it on bank 1.

Check these first

• A failed EGT sensor on bank 1 sensor 3
• A sensor 3 circuit with an open or short
• A bank 1 exhaust restriction that raises temperature
• Engine misfire or overfueling on bank 1

What to do next

1. Read EGT sensor bank 1 sensor 3 on a scan tool
2. Compare sensor 3 to the other bank 1 EGT readings
3. Test the sensor 3 circuit for open and short faults
4. Check bank 1 for misfire or a rich fuel condition
5. Replace the EGT sensor if it reads out of range against the others
6. Clear the code and retest
