Q: What does code P247F mean?

Exhaust Gas Temperature Out of Range Bank 2 Sensor 4. P247F indicates that the engine control module has detected an exhaust gas temperature reading from bank 2 sensor 4 that falls outside the expected range for the current operating conditions. The computer compares the sensor signal against modeled exhaust temperatures and flags the code when the voltage or calculated temperature is implausibly high, low, or erratic for a sustained period.
