What does code P2475 mean?

Q: What does code P2475 mean?

Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 4. P2475 means the powertrain control module (PCM) has detected an abnormally low voltage signal from the exhaust gas temperature (EGT) sensor located after the bank 2 catalytic converter, which is sensor 4. The PCM expects a voltage within a calibrated range that corresponds to a specific exhaust temperature, and a low reading tells it the sensor circuit is grounded, shorted, or the sensor itself has failed.
