What does code P2482 mean?

Q: What does code P2482 mean?

Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 5. P2482 means the powertrain control module (PCM) has detected an abnormally high voltage on the exhaust gas temperature (EGT) sensor circuit for bank 1 sensor 5, which is typically a post-catalyst or downstream sensor on that bank. The PCM interprets this high voltage as an excessively hot or open circuit condition and sets the code to protect the engine and emissions system.
