Q: What does code P247D mean?

Exhaust Gas Temperature Out of Range Bank 2 Sensor 2. P247D indicates that the engine control module (ECM) has detected an exhaust gas temperature (EGT) reading from bank 2 sensor 2 that falls outside the expected range for the current operating conditions. The ECM compares the sensor signal against modeled exhaust temperature and flags the code when the voltage or calculated temperature remains too high or too low for a calibrated period.
