Q: What does code P2468 mean?

Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 3. P2468 means the powertrain control module (PCM) has detected an abnormally low voltage signal from the exhaust gas temperature (EGT) sensor located after the diesel particulate filter (DPF) on bank 2 of the engine. The sensor circuit is reporting a value below the expected range, which the PCM interprets as a short to ground, an open circuit, or a failed sensor.
